MELCHIORITES EMERICI Iridescent Fossil Ammonite Mother of Pearl Shell Albian Cretaceous Madagascar Genuine

Discover a stunning, genuine piece of ancient history with this MELCHIORITES EMERICI iridescent fossil ammonite, preserved with beautiful Mother of Pearl shell. This exceptional specimen dates from the Albian Stage of the Early Cretaceous Period (approximately 113 to 100 million years ago) and was found in the fossil-rich layers of Mitsinjo, Madagascar.

Geology & Origin:

Mitsinjo, located on the western coast of Madagascar, is renowned for its Cretaceous marine fossil beds. During the Albian stage, this region was submerged under a shallow sea, providing perfect conditions for marine life such as ammonites to thrive and fossilize. Over millions of years, mineralization preserved the shell's intricate structures, with the original aragonite layer transforming into breathtaking iridescent "Mother of Pearl" (nacre), creating shimmering hues across the fossil's surface.

Fossil Type & Species:

Type: Fossil Ammonite (Extinct marine cephalopod)

Species: Melchiorites emerici

Preservation: Original shell with iridescent mother of pearl layer

Behold the dazzling colors of an iridescent ammonite (Placenticeras intercalare)! A relative of today’s squids, this ammonite lived some 80 million years ago near what is now Alberta, Canada. This fossil’s spectacular coloration is the result of millions of years of high temperatures and pressures. As these forces acted on nacre in this ammonite’s shell, it was transformed into a gemstone known as an ammolite. Along with amber and pearl, ammolite is one of only a handful of gems made by living organisms.

You can spot this rare specimen in the Louis V. Gerstner, Jr. Collections Core in the Museum’s Richard Gilder Center for Science, Education, and Innovation! Plan your visit.

Fossil Friday: Ammonite

Ammonite is a preserved shell belonging to an Ammolite or other creature belonging to the subclass Ammonoidea. These fossils are the remains of an extinct marine cephalopod (mollusc) from the Jurassic period (about 200 million years ago) to the late Cretaceous period (about 66 million years ago). Ammonites died off at roughly the same time as flightless dinosaurs. Ammonites were a unique group of creatures, likely having eight separate arms, resembling a coleoid (squids, octopuses, and cuttlefish), while the shell and it's shape closer resembling a nautilus. An estimated 10-20 thousand species of ammonite have been discovered, so no two fossils will be the same. The largest ammonite specimen found was over 1.8 metres (approx. 5.9 feet) in length, while being an incomplete fossil. Ammonite can be found at any location where prehistoric oceans once were. Ammonite is often used as an index fossil, being used to date the approximate age of the rocks it is embedded in. Ammonite is considered to be one of the world's rarest gemstones when the shell appears iridescent.

It is crucial to be aware of laws and regulations governing fossil collection in your area. Many places require all fossils found to be sent to a palaeontologist, and have strict regulations on the selling of locally found specimens.

Here's a rainbow iridescent ammonite shell

Sadly my camera cannot capture how beautifully the light bounces off its many hues

pretty!!

[jovianaquarium]

ok so my lovely mutual @icarrymany dared me to post proof of my rock/min collection so this is his fault >:)

im not gonna go into depth on all of the samples bc 1. i dont remember the details on all of them lol and 2. it would take. forever

so instead ill talk a little abt one or two of them per section :3

first up: tumbled minerals!

i have a bunch more of these but after becoming a geology student they kind of piss me off bc raw minerals often look way cooler and tumbling removes the crystal habit (and also makes them harder for me to identify hgjhfd)

first image, from left clockwise: (possibly) blue lace agate, chrysocolla. labradorite, snowflake obsidian, moss agate, brown agate, and two samples of tigers eye

2nd image: up close picture of one of the tigers eye crystals, showing its lighter banding

3rd image: up close picture of the labradorite from a different angle, showing its pale green luster

my absolute favorite mineral ever is labradorite also!! i think its luster is gorgeous and ive heard it represents transformation and change, and i first got this sample back when i had just come out as trans :)

i dont really have a lot to say abt these unfortunately lol

anyway. next is fossils!!

1st image, clockwise from bottom left: trilobite cast fossil, tumbled stromatolite, dinosaur bone (? got this one at a mineral stall and the dude said it was a dino bone, didnt think to ask details lol), plant fossil, coral fossil, assorted fossil molds (mold as in taking the shape of something, not spores) in wackestone, mosasaurus tooth, crocodile (?) tooth, 2 ammonites, a turtle scute, a crinoid stem, and a (broken) orthoceras

2nd image: up close pic of the assorted fossil molds, which include horn corals (circular with ridges toward center, hole in middle), crinoid stems (cylindrical with ridges perpendicular to long sides), and shells

3rd image: up close pic of larger ammonite, with iridescent luster due to aragonite (a polymorph of calcite) replacing the calcite of the shell

4th image: up close pic of dubious tooth. i found this on a field trip about a year ago while looking for shark teeth. this is not a shark tooth. idk what it is. i think it might be from a crocodile but i havent been able to fully identify it lol

now.... raw minerals!!!!!

1st image, clockwise from left: moss agate, talc, serpentinite (this one is a metamorphic rock but i accidentally put it with the minerals and dont want to retake the pics. other geologists you may come kill me), two calcite samples, and a tiny topaz @ramones2 gave me

2nd pic: close up on the topaz crystal, which is light orange (if u leave these in the sun they get bleached and lose their color </3)

3rd pic: close up on one of the calcites. its crystals are a bit more squared and close-knit than the next calcite, and appear more white in color. there are also some small purple fluorite crystals mixed in. i traded with a classmate for this one lol

4th pic: close up on the other calcite. this ones crystals are more rounded and transparent.

5th pic: close up on the serpentinite. serpentinite is metamorphosed from peridotite, which makes up the earth's mantle (if youve ever heard that the mantle is actually green, that is true!! the green comes from olivine mostly, but also some pyroxenes). when peridotite is lifted up to the surface and comes into contact with water, olivine gets very unhappy and serpentinizes, or hydrothermally metamorphoses (water + some heat + olivine = cool as fuck snakeskin rock)

6th pic: another close up on the serpentinite, this time wet. you can see the serpent-like pattern a bit better.

finally: rocks :3

1st image, clockwise from bottom left: amphibolite, sedimentary rock with calcite vein (i dont remember what this one is lmao), malachite-bornite ore, iron-stained sandstone(?) with chalcedony/agate, phyllite, sandstone trace fossil of a burrow, and meteoric rock possibly with iron

2nd pic: close up on the ore, showing the malachite vein. it's almost powdery, with a gradient of light blue on the edges to teal in the center

3rd pic: another close up on the ore, showing the bornite vein. it's iridescent like an oil slick, with the main color being purple. this one is often called peacock ore for its colors :)

4th pic: . im gonna be honest i have no fucking clue bro. i think the mineral in it is agate/chalcedony (the lighter gray/white areas) and the red parts are an iron-stained sedimentary rock, but i forget if its siltstone or sandstone or smth else. idk. it looks cool.

bonus: extra pic of my rocks for further proof of collection

hope u enjoyed o7

The Rare Gemstone Ammolite.

This dazzling iridescent fossil of an 80 million year old ammonite measuring two feet in diameter was discovered near Alberta, Canada and is a particularly rare example of an ancient sea creature that went extinct at the same time as most dinosaurs. The spectacular coloration is the result of millions of years of high temperatures and pressures acting on the animal’s shell to create a gemstone known as ammolite.

How to Spot Authentic Ammolite: A Buyer’s Guide

Okay, let's begin at the basics: purchasing gemstones. First of all, gemstones need to be natural, especially those as rare and stunning as ammolite. This buyer's guide will give you a heads-up on the ammolite world by providing you with all the information that you should know to identify authentic ammolite gems, gemstones, and stones.

What Do You Understand by Ammolite?

Among the few gemstones offered with its own excitement spark, ammolite is extracted from the fossilized shell of ammonites, which are classified as being part of a cephalopod group. Its iridescence and bright colors are gorgeous, hence the need to include it in many jewelry. But with increased demand comes increased circulation of fakes and synthetics; some essential things to look for in establishing the authenticity of an ammolite gem are presented below.

Key Characteristics of Genuine Ammolite

Color Play and Luster

Real ammolite gemstones demonstrate an amazing display of colors, ranging from greens to reds, blues, and purples. This dancing play of color is called "iridescence," which is characteristic of natural ammolite. When looking at a piece of ammolite stone, you should see:

Intensity: Color should be strong and alive

Dimension: Ammolite is often characterized by multiple levels of color, giving the stone a three-dimensional effect.

Surface Luster: Authentic ammolite would have a natural luster and not a plastic appearance.

2. Texture and Surface Features

A real ammolite gemstone should have an even surface with smoothness; however, it may carry inclusions or other imperfections that give the stone character. Be looking for these features:

Natural Imperfections: Authentic ammolite would seem to have slight aberrations or have patterns, and this would be evidence that it was naturally formed.

Transparency: While ammolite is partially translucent, it cannot be transparent.

3. Weight and Density

Ammolite gemstones weigh relatively light compared to the weight of other comparable gemstones. If you are looking at a gem ammolite, be sure to pay attention to:

Weight: If the stone is too light, then it likely is synthetic or an imitation.

Density Test: Natural ammolite has a specific gravity of 1.2 to 1.5. Weigh the stone relative to size, if possible, too.

4. Documentation and Authenticity

Ask for any documentation when you purchase your ammolite gem. A dealer will guarantee that the stone is authentic with a document stating so. Here's what to watch for:

Gemological Reports: Certification reports from laboratories that are well known to verify that the stone is genuine ammolite.

Detailed Descriptions: The actual certification would be an ammolite gemstone with a clear description stating its origin and quality.

How to Buy the Stone

Ammolite purchase individuals have to get an idea of whom to acquire the gemstone. Following are the various ways through which a person could get the best vendor.

Reputation: Choose a reputable seller that has at least some kind of history in the world of gemstones, preferably with high scores in customer reviews.

Transparency: The reputed seller must provide information about the sourcing of the ammolite stones and proper descriptions of the particular stones on sale.

Return Policy: The return policy of the seller is an important one in case the gem fails to meet your expectations.

Conclusion

To collect real ammolite gems, keen eyes and a bit of information about its wonderful features are required. Compare colors, textures, weights, and official certificates, and then you can confidently choose the wonderful ammolite gem for your collection. Make sure you purchase from reputable distributors to guarantee it's a natural beauty.
