Grandidierite: The Rare Gem from Madagascar
Introduction
Grandidierite is a gemstone considered one of the rarest in the world. Its extraordinary scarcity, rating among the top ten rare stones globally, makes it a gem collector's dream. With a hardness of 7.5 on the Mohs scale, it's not only exceptionally rare but also durable enough to be a centerpiece in jewelry. It was first discovered in Madagascar in 1902, named after the French explorer Alfred Grandidier, and is found in various colors, displaying trichroic pleochroism, ranging from dark blue-green to pale yellow or colorless. It's highly regarded for its potential to predict the future, purify negative energy, and enhance willpower, self-confidence, passion, and execution power.
Origins of Grandidierite
Grandidierite was first discovered in southern Madagascar in 1902. This gemstone is named after the French explorer Alfred Grandidier, who was an expert in the geography and natural history of Madagascar. It's a borosilicate mineral with an orthorhombic crystal structure and is found in colors ranging from light to dark green, light blue, or dark blue-green. One of its most unique features is trichroic pleochroism, allowing it to display different colors depending on the viewing angle.
Rare and Beautiful
Grandidierite is one of the world's rarest gemstones, often listed among the top ten rarest varieties. Its rarity, combined with its intense, vivid colors, makes it highly sought after by gem collectors. This gem's hardness, rating at 7.5 on the Mohs scale, ensures it can withstand the rigors of being set in high-quality jewelry. Whether in rings, earrings, pendants, or bracelets, Grandidierite adds a touch of refinement and beauty to any piece of jewelry, making it a perfect choice for a range of occasions.
Caring for Grandidierite
Grandidierite is generally self-treated because of its durability, but some stones may have inclusions or imperfections. Due to its cleavage and brittle tenacity, it is recommended to avoid mechanical cleaning systems. Instead, use a soft brush, mild detergent, and warm water to clean Grandidierite. Be cautious with ultrasonic and steam cleaners, as they can damage the stone. Additionally, avoid exposing the gem to heat and harsh chemicals, as this can affect its appearance and quality.
Metaphysical Properties
Grandidierite is associated with the heart and throat chakras, which are believed to contribute to physical and emotional well-being. It is said to help eliminate negative emotions such as anger, jealousy, and resentment. This gemstone can also aid in promoting clarity in life, making choices, and enhancing energy levels. It is believed to have the power to heal strained relationships and offer a sense of inner peace and purpose.
In conclusion, Grandidierite is a truly exceptional gemstone, both for its rarity and its metaphysical properties. Its beauty, rarity, and durability make it highly prized among gem collectors, and its potential to cleanse negative energies and promote personal well-being only add to its allure. Whether as a collector's item or a personal talisman, Grandidierite truly shines in the world of gemstones.

# Dcu x Dp 142
In the center of Gotham there stood two unique and strange statues.
One of the statues was of a humanoid man that stood up straight at 5 feet 8 inches both of his hands resting on the top of a sword that was in front of him. He wears a cape that was sculpted to look like there is fur on the edges a chain holds the cape in place, where the chain meets the cape there is a human-looking skull on both sides. His head is slightly tilted down so if you stood a couple of feet away he would be looking at you, he has a soft open smile on his face if you look closely enough you can see he has fangs. His hair looked as though it was floating, on top of his head sat a crown, he had pointy ears the hands that rested on top of the sword had nails that looked like claws. He wears a bodysuit baggy pants and what looks like combat boots, on the center of his bodysuit there is a D with a P inside symbol.
At his feet lays the other statue, a big Rottweiler. The dog came up to his hip while lying down and was at least 7 feet long, his head was by the man's hip and his body was curled behind the man's legs. The dog had his mouth open partially with his tongue hanging out you could see his teeth when looking at him the dog's head was looking at the same spot that the man's head was looking at. The dog wore a collar with spikes at the front there was a tag that had the name Cujo and on the back of the tag the same symbol that was on the man's bodysuit. One of the dog's paws was resting on top of an actual dog toy made of rubber.
They both are on a stone pedestal that is about 3 feet tall and 6 feet wide the pedestal is decorated with symbols of death and protection. You can find other humanoids sculpted into the pedestal and over time people have noticed that you can also find the Bats and Birds symbols on the front of the pedestal and in the corners you can find symbols that represent the rogues.
The statue had both precious gemstones and metals decorating it. The statue of the dog had the least, the dog's eyes are made of rubies the claws are made of obsidian. The spikes on the collar seemed to be an actual metal, in between each spike a star sapphire sits. Under each spike, a small chain is attached and connects to the next spike.
The man had much more, his eyes were made of Alexandrite stones but changed from Emerald to Sapphire and they changed at random. His freckles are a combination of Opal stone and Moonstone that are spread across his cheeks and nose, and his claws and sword are made of obsidian. The cape outside of the cape has small silver spots, and on the inside, there are many different gemstones that are decorated to look like stars in the sky. Crown is made of a combination of Amazonite and Malachite and is decorated with Ammolite, papagoite, shattuckite, and star sapphire. Bracelets are made of Azurite with grandidierite, he has Paraiba tourmaline earrings with one star sapphire earrings hanging from his right ear. He has three rings one made of Garnet, the second one is made of Grandidierite, and the last one is made of Jeremejevite. On his left hand, there are some cracks that disappear underneath the sleeves of his bodysuit and appear again on his left cheek the cracks seem to be filled with emerald ( the bats know it's not emerald it's crystallized LaArus water ) it is like a kintsugi.
Several things make these two statues very unique
1. No known history there is nothing about who made the status or why they were placed there
2. Destroy or steal no matter how many times people try to blow up the statues or smash them no damage can be done, and no one can remove any of the gemstones that are on them. The person would also become sick or be injured after trying
3. Can't be Recorded or take pictures it's difficult to get clear pictures and videos unless they're from an older model
4. No one can buy or take them many wealthy people have tried to buy the statues and take them but every time that's happened the machines and cars that were there to move them were shut down and the person who tried to buy them would get extremely sick and be haunted by nightmares, night terrors and paralysis.
5. Crused and blessed as mentioned before people would get sick be injured get nightmares, night terrors, and/or paralysis. People that stand in a 15 feet radius of the status can't get infected by any of the gass that are release and people that are already infected by them are inside the radius will get cured, and has also protected people from getting attacked inside the circle .

I don’t know when I’m going to have the time to finish this, so here, the start of another Mist side story because I can’t help myself apparently. About 10 years into her time with e1!Peridot. The sunstone here is the same one e1!Peridot helped back when they both received their pearls, and she’ll probably be back for her own thing eventually.
As she had done countless times before, Pearl dusted while her mistress was out. Peridot never told her to, but it was such a small task in such a small space that Pearl did it just to have something to do. She was done exploring the top tray of data crystals in Peridot's storage bin and wanted to be at least a little active before settling back onto the couch and continuing with the next. She had no idea what Peridot was doing, but in the tenth year of their time together, she no longer worried about being caught doing something other than work or waiting in a corner. The tune she hummed as she dusted was from one of those data crystals--something she'd never heard before in court while trailing after Trapiche Emerald, and certainly nothing Zircon or Grandidierite would ever listen to. It was a love song, one of many out of a performance by a larimar and addressed to some unknown gem. Love seemed like such a pretty idea. It was probably nothing she would ever experience herself, but it was nice to dream of being cared for like that. There was a buzz at the door. Pearl froze; the sunstone who visited periodically knocked one way, the bismuth who did building maintenance knocked another way, and peridots hammered the door until she answered. Peridot didn't usually get visitors who used the buzzer. She set her dustcloth aside and glanced at the screen that showed whomever was at the door--it was the sunstone, but there was something unusual about how rigid she looked. Pearl's good mood dropped. Sunstone was here on official business. She had to be. Sunstone strode through as soon as Pearl opened the door for her. Her red and orange freckles glittered in the light as she moved. Sunstone stopped and looked at the viewscreen, her back deliberately turned to the storage bin in which Peridot kept her data crystals. "Peridot Facet-1F Cut-2AA was taken in for interrogation over her past activities. I am here to do inspection. Complete your task before I finish." Dread shot through Pearl as the reality of Sunstone's words sank in. She had time to herself here. It was safe. No one hurt her. What would happen to her if Peridot disappeared? Would she return to the harvest pool or be sold again? Her breath caught in her throat as her thoughts spiralled through increasingly dark paths. She had such a good life here that anything else would surely be torture-- Sunstone didn't bother to turn around. "Complete your task, pearl." It took a moment for her to finally understand the intent behind Sunstone's words. She was being given a chance to hide anything that might be used against Peridot. She pulled the storage bin into her gem, taking care not to rush the process and jostle the data crystals out of their trays. The tools could stay, she supposed. There was nothing special about them. Nothing else seemed like it would incriminate Peridot. "I'm done," she said quietly, her head bowed and hands folded in front of her as if she was talking to a superior gem and not the sunstone who grinned easily and talked fondly about her pearl. Sunstone turned and looked behind her at the place where the storage bin once stood. She nodded approvingly and moved on to examine the rest chamber. When she returned, she spoke into the recording chip on her chest. "Let the record show that the examination of Peridot Facet-1F Cut-2AA's quarters has turned up nothing of value to Sphalerite Facet-4D Cut-7GN's investigation. It is the considered opinion of this sunstone that this investigation is a waste of time and resources. The pearl will be delivered to Star Sapphire Facet-3 Cut-6SN's keeping until this investigation is completed. Off." The chip blinked once and went dormant. When it did, Sunstone relaxed. "Sorry about this mess. Sphalerite is annoyed that she was passed over for the gifting candidate list again and has some gravel up her form about some old history that no one actually cares about. She's going after anyone who might have a less-than-stellar record." Pearl was silent as she thought over Sunstone's words, unsure of what Peridot could have possibly done to incur anyone's wrath. She was so polite to everyone, even Pearl. There was nothing of any real value in the data crystals, but those hollows in Peridot's larger tools were there for a reason. Dare she ask what any of it meant? Sunstone shifted on her feet, as if uncomfortable with the silence. "Well. Er. Sphalerite will probably have someone else go over these quarters again soon, so we should probably get you to Star Sapphire before then. Ready?" With a nod, she followed Sunstone out of the apartment. Save for the bismuth patching up the floor tiles several feet away, the corridor was empty. Sunstone, who had always been gregarious, seemed like she was uncomfortable with talking to her without Peridot around. "So! Um. Pearl says hi."
She doubted it, largely because she couldn't imagine another used pearl acting so familiar with her owner, but it was nice of Sunstone to try.
(tbc sometime hopefully before the 24th)

5 Things to Know About … Grandidierite
Tumblr media
When I was in Tucson, the team at Omi Gems’ booth treated me to something special: a viewing of not one but six grandidierite gems. I had heard of the gemstone before but had never seen one in person. As it turns out, not many people have. They’re rare, and let me tell you, they’re gorgeous. Grandidierite is bluish-green to greenish-blue, with the blue component increasing with the iron content, according to the GIA. It’s a 7.5 on the Mohs scale, making it suitable for use in jewelry (when available), but according to the International Gem Society, it is difficult to cut because it has good cleavage in two directions. It also displays trichroic pleochroism, meaning it can show three different colors depending on the angle at which it’s viewed: dark blue-green, pale yellow or colorless, or dark green. In honor of the stone I was excited to see and learn about in Tucson, here are five things to know about grandidierite. 
1. It was first discovered in Madagascar. French mineralogist Alfred Lacroix found the first reported samples of grandidierite in 1902. He discovered the gemstone at the cliffs of Andrahomana in southern Madagascar, according to the GIA. 2. It was named for someone. As is the case with a few other minerals ending in “ite,” grandidierite was named after a person. Lacroix christened the mineral “grandidierite” in honor of another Alfred: French explorer and naturalist Alfred Grandidier (1836-1912), who was the first explorer to describe Madagascar in detail, according to the Cambridge History of Africa. He devoted his life to gathering information for his massive “Histoire physique, naturelle et politique de Madagascar,” which was 38 volumes long.
Tumblr media
3. It has since been found elsewhere. In addition to Madagascar, GIA said other reported sources of the mineral include New Zealand, Norway, Suriname, Algeria, Italy, Malawi, India, the United States, Canada, Antarctica and the Czech Republic. Since its discovery more than a century ago, very little gem-quality grandidierite has surfaced and most of what has been found is translucent. However, a 2014 discovery of more transparent material outside of Tarnomaro, Madagascar, near the site where the first pieces of grandidierite were found, has resulted in several fine quality faceted stones, according to the Gemmological Association of Great Britain’s Gems & Jewellery spring issue.
4. It is extremely rare. Despite the number of sources, grandidierite is still extremely rare; pockets tend to be small and quickly become depleted. Much of the material that comes out of the ground is opaque, IGS said. As mentioned before, even when gem-quality material is produced, it’s often translucent (semi-transparent), and is thereby cut into cabochons ranging in size from about 1 carat to 10 carats and up. According to GIA’s Gems & Gemology, gem-quality grandidierite of “facetable size” was “almost unheard of” in the market before the summer of 2015. Bangkok-based gemstone dealer MultiColour Gems said on its website that the ratio of gem-quality crystals to rough is about 1 in 10,000. The company noted that the Tranomaro deposit, where the 2014 discovery occurred, has produced only about 60 grams (300 carats) of eye-clean crystals. Given its rarity, fine grandidierite gems can demand significant prices. For example, gem dealer and Mineral Art manager Brice Gobin is quoted in the Gems & Jewellery article as saying that a buyer paid $50,000 in 2003 for the first known transparent faceted grandidierite, which weighed only 0.29 carats, a fact confirmed by GIA.
Tumblr media
Even so, minimal supply goes hand-in-hand with low demand and a lack of knowledge about the stone among many jewelers, according to Gobin. “Grandidierite is too rare to be able to provide the jewelry market,” he is quoted as saying. “No supply, no demand; it’s as simple as that.” 5. You can see grandidierite gems in New York right now. For those who haven’t seen grandidierite in person or are looking for the perfect collector gemstone, one Manhattan gallery provides the perfect opportunity. Gobin sourced a collection of grandidierite gems from the Tranomaro region of Madagascar over an 18-month period, Gems & Jewellery reported. The selection included some 20 gems weighing between 1 and 9-plus carats. Three of Gobin’s grandidierite gemstones will be on display at the Wilensky Gallery in New York City through at least June, representing the gallery’s foray into faceted gemstones. They weigh 2.86, 3.14 and 4.96 carats and are priced at $69,000, $78,000 and $129,500, respectively. I was lucky enough to get to see those, too, during a recent WJA event at the gallery, and I’m telling you: Run, don’t walk, to see these gems before they’re gone.

10 Gemstones that are Rarer than Diamonds
Diamonds are by far the most coveted gemstones in the world. But what makes diamonds so revered is not their scarcity, but rather tactful advertising on behalf of diamond mining corporations like DeBeers. There are actually a number of colorful gemstones that are considered to be much rarer than diamonds. Because of their rarity, these gemstones are not frequently found in jewelry. For this reason, they’re less well-known than gems like sapphires and emeralds, but certainly not any less beautiful.
Here are the top ten rarest gemstones (in no particular order):
1. Taaffeite
Image source
This extremely unusual gemstone was discovered accidentally in 1945 by Austrian geologist, Count Edward Charles Richard Taaffe. While combing through a box of spinel gems, Taaffe noticed there was one that was different from the rest. Because Taaffe was the first to discover taaffeite, the stone was named after him. Taaffeite can occur in colors ranging from deep purple to red, though red is the most uncommon. Surprisingly, this stone scores an 8 to 8.5 on Moh’s Scale of Hardness, making it unusually durable. Very few taaffeite gemstones have been found since their initial discovery. In fact, the only known deposits are in Sri Lanka, Tanzania, and China.  If you’re lucky enough to find one of these dazzling gems, expect to pay about $1,500 to $2,500 per carat.
2. Tanzanite
Image source
Though tanzanite can be purchased rather easily, it is still considered rare because of its scarcity. This gemstone is found exclusively in Tanzania, specifically the foothills of Mount Kilimanjaro. Because this is the only known location where tanzanite can be mined, it is predicted that the world’s supply will be depleted within 20-30 years. Iconic jeweler, Tiffany & Co. famously used tanzanite in their designs, further driving up the demand for these beautiful gems. Tanzanite’s deep violet and blue hues make them comparable to sapphires, and they’re often used as an affordable alternative. Though as supply decreases, tanzanite’s value will likely skyrocket. Presently, you can anticipate one of these stones to cost you roughly $600 to $1,000 per carat.
3. Black Opal
Image source
Opals are a rather common gemstone, and can be found in many jewelry stores. However, black opals are a unique exception. Black opals mesmerize with their celestial colors swirled against an ink black backdrop. It’s no wonder they’re considered to be so exquisite! Similar to tanzanite, black opals are found solely in one location—along the Lightning Ridge in New South Wales, Australia. To own one of these captivating gemstones will cost you around $2,300 per carat.
4. Jadeite
Image source
Jadeite is highly regarded by Chinese, Mayan, and Maori cultures, inspiring a rich history of mythology. The stone was said to have been used in ancient Mesoamerica for fashioning tools and other weaponry. Though recognized for its varying shades of green, jadeite naturally occurs in lavender, yellow, blue, and a variety of other colors. Jadeite’s translucent appearance and smooth texture are what make it most valuable. The largest jadeite deposit is in Myanmar, though stones have been unearthed right here in California! Jadeite currently costs approximately $30,000 per carat.
5. Red Beryl
Image source
Red beryl derives its bright red pigment from the trace element manganese. This gemstone is a relative of emerald, aquamarine, and morganite. Red beryl is primarily mined in the Wah Wah Mountains of Utah, though small deposits have been located in Mexico and New Mexico. Most stones that are mined are not large enough for faceting, though if you’re fortunate enough to find one, it could cost you as much as $10,000 per carat.
6. Benitoite
Image source
Benitoite is found primarily in San Benito County, California, which is why California adopted the stone as their state gem. Other specimens have been located in Arkansas, Montana, Australia, and Japan, as well as other regions within California. Though, the only gem quality stones have been produced exclusively by the San Benito mine. Benitoite is sometimes referred to as the ‘blue diamond’ for its mesmerizing translucent blue color. Because of its rarity, most gem quality benitoite is a carat or less, though the largest ever found was nearly 16 carats. To get your hands on one of these gems will cost you about $3,000-$4,000 per carat.
7. Alexandrite
Image source
Deemed the “emerald by day, ruby by night”, alexandrite has unique color-changing properties that make it highly desirable. In lighter environments, alexandrite sparkles a rich blueish green color, while darker settings cause the stone to transition to a vivid magenta or purple tone. This one-of-a-kind gemstone was first discovered in the mountains of Russia in the 1830s. It was highly coveted by the Russian aristocracy, deriving its name from Czar Alexander. New deposits have recently been unearthed in Brazil, East Africa, and Sri Lanka. Perhaps these new locations will yield enough to help ease prices, but in the meantime alexandrite can cost as much as $12,000 per carat.
8. Musgravite
Image source
Musgravite was first discovered in the Musgrave Range of Southern Australia. It is from this range that it derives its name, though traces have now been found in Sri Lanka, Madagascar, and more. Musgravite is found in colors ranging from a greenish gray to purple, and scores an 8-8.5 on the Moh’s Scale of Hardness. This score makes musgravite ideal for use in jewelry, but unfortunately quantities are too limited. Despite the discovery of new deposits, availability of musgravite is still scarce, in turn making them quite pricey. The cost for one of these rare beauties? Specimens have sold for as much as $35,000 per carat!
9. Painite
Image source
In 2005, painite took the crown as the world’s rarest gemstone according to the Guinness Book of World Records. At the time, there were only 25 known specimens in existence. Today, that number hasn’t increased by much, with the only known source of painite being in Myanmar. This gem can occur in colors ranging from brown to red, and even pink. Painite is pleochroic, meaning that it can appear to change colors when viewed from different angles. So what does the world’s rarest gemstone cost? If you’re able to locate painite on the market, it may cost you as much as $50,000-$60,000 a carat.
10. Grandidierite
Image source
Grandidierite was discovered in Madagascar in 1902 by a French mineralogist, Alfred Lacroix. He named his treasure after French explorer and naturalist, Alfred Grandidier. Since his initial finding, small samples of grandidierite have been found in Namibia and Sri Lanka, though very few have been gem quality. Grandidierite commonly occurs in a teal blue color, and can transmit light due to it being pleochroic. Specimens that are fully transparent are considered the rarest. Forbes ranked this gemstone the third rarest on earth, with prices as high as $20,000 per carat.

Grandidierite commonly occurs in a teal blue color, and can transmit light due to it being pleochroic. Specimens that are fully transparent are considered the rarest. Forbes ranked this gemstone the third rarest on earth, with prices as high as $20,000 per carat.

History About Grandidierite Gemstone
"Grandidierite: The Rarest Gemstone on Earth"
Introduction:
Grandidierite is an extremely rare and precious gemstone known for its exceptional beauty and scarcity. It ranks among the top ten rarest stones in the world and has been isolated for an astonishing nineteen million years. With a hardness of 7.5 on the Mohs scale, it is a durable gemstone composed of magnesium, aluminum, and traces of iron. Grandidierite displays trichroic pleochroism, exhibiting dark blue-green, pale yellow or colorless, and dark green hues. Its journey began with its discovery in Madagascar and it has since captivated gem collectors and enthusiasts worldwide.
Historical Significance and Rarity:
Grandidierite was first discovered in 1902 in southern Madagascar, an area rich in geological wonders. It was named after Alfred Grandidier, a French explorer and expert on the geography and natural history of Madagascar. Since its discovery, Grandidierite has been highly sought after due to its rarity and stunning color. In 2003, a transparent Grandidierite gemstone was found in Sri Lanka, expanding its known sources. While other localities have reported Grandidierite finds, South Madagascar remains the primary source of high-quality stones.
Physical Properties and Aesthetic Appeal:
Grandidierite is treasured for its unique physical properties and alluring appearance. Its trichroic pleochroism sets it apart as the only gemstone capable of displaying three different colors simultaneously. Depending on the viewing angle, it can appear as dark green, colorless, light yellow, or dark blue-green. The gemstone forms elongated crystals with a bluish-green or greenish-blue hue. Its transparency adds to its luminous appeal, making it a desirable choice for jewelry.
Astrological and Spiritual Significance:
While Grandidierite does not belong to a specific zodiac sign or serve as a traditional birthstone, some individuals may consider it as a substitute for other blue or green birthstones like aquamarine or turquoise. Specialists associate Grandidierite with the throat chakra, primarily influenced by the stone's color. It is believed to have metaphysical properties that purify unintentionally stored negative energy and enhance willpower, self-confidence, passion, and execution power.
Care and Handling:
Grandidierite requires minimal additional treatment due to its durability. However, it is essential to handle this precious gemstone with care. Mechanical cleaning methods should be avoided, as the stone has cleavage and can be brittle. Instead, use a soft brush, mild detergent, and warm water to clean it. Steer clear of ultrasonic and steam cleaners, as they can cause damage and scratches. Protect Grandidierite from exposure to heat and harsh chemicals to maintain its appearance and quality. Store Grandidierite jewelry in a clean, dry place, preferably in a fabric-lined jewelry case to prevent scratches.
Conclusion:
Grandidierite stands as one of the rarest gemstones on Earth, captivating gem collectors and enthusiasts alike. Its scarcity, combined with its extraordinary beauty, places it among the most coveted stones in the world. With its mesmerizing trichroic pleochroism, high hardness, and diverse color variations, Grandidierite is an excellent choice for center stones in jewelry. Its metaphysical properties and connection to the heart and throat chakras make it a symbol of purity and empowerment. Whether treasured for its rarity or appreciated for its stunning aesthetics, Grandidierite truly stands out in the world of gemstones.
