Argyle tender breaks records during pandemic following pink diamond mine closure
The collection consisted of 62 rare pink, red, blue and violet diamonds from its Argyle mine in West Australia. The mine ceased production last month following 37 years of production. It’s said that the Argle Mine was responsible for more than 90% per cent of the world’s annual natural pink diamond supply.
“It is an extraordinary opportunity and a privilege to be part of the history-making Argyle diamond mine. We are humbled to be the custodians of these iconic rare jewels and are delighted to be part of their enduring legacy.”HARSH MAHESHWARI
The 2020 tender, which had to be conducted under COVID ‘conditions’, allowed participants to view the stones using live streaming and a virtual portal at locations in Antwerp, Singapore and Perth, Australia, due to travel restrictions. Technology that enabled exacting colour calibration and magnification of the diamonds was also used during the event.
Hong Kong-based Kunming Diamonds was the successful bidder for 35 lots, including the coveted Argyle Eternity. The 2.24-carat fancy-vivid-purplish-pink, which Rio Tinto representatives say, is “the most valuable diamond in the collection and the most valuable Fancy Vivid diamond in the Tender’s 37-year history.”
Harsh Maheshwari, director of Kunming Diamonds said, “It is an extraordinary opportunity and a privilege to be part of the history-making Argyle diamond mine. We are humbled to be the custodians of these iconic rare jewels and are delighted to be part of their enduring legacy.”
He told Jeweller that he doesn’t have plans for the Argyle Eternity as yet:  “We will see in 2021, but it could be part of a museum or at an art gallery exhibit. It’s meant for a connoisseur, collector, someone who appreciates and respects such a rare diamond.”
Other record-breaking diamonds from the tender included the Argyle Infinite, a 0.70-carat oval fancy dark violet-grey diamond which now becomes the most valuable diamond in this colour category ever produced at the mine.
“I am thrilled with my success at this year’s Tender and the exciting design possibilities unleashed by these colourful and uniquely Australian jewels.”JOHN CALLEIJA
Patrick Coppens, Rio Tinto’s general manager sales and marketing said, “We are delighted with the results of the 2020 Argyle Pink Diamonds Tender, a testament to the unique Argyle ore body and its place in the history of the world’s most famous diamonds.”
Also included in the 2020 offering were 12 additional lots of “carefully curated and never to be repeated sets of miniature rare Argyle pink, red, blue and violet diamonds”, named The Petite Suites.
They weighed 13.90 carats in total and were collected over a five-year period, with each parcel designed to strike a balance between size, shape, colour and clarity.
The Petite Suites were of particular interest to high-end designers. Local Sydney jeweller, John Calleija, successfully bid on several lots. He has a long tradition in securing and working with Argyle pinks.
“I am thrilled with my success at this year’s Tender and the exciting design possibilities unleashed by these colourful and uniquely Australian jewels,” Calleija said.
“As next year will be the last Argyle tender, we will bid on all stones, since the goods will become super rare, in high demand, and expensive.”Shmulik Polnauer, Leibish & Co
In October 2018 he unveiled the ‘Argyle Dreaming’ jewellery set, and which debuted in New York City. The necklace and ring featured 673 pink, white, yellow, blue and champagne diamonds from the Argyle Mine in Western Australia, set in gold mined from the Rio Tinto’s Kennecott site in Utah, USA. The pieces are valued at $US1.1 million ($AU1.63 million).
Rio Tinto will hold its final Argyle Pink Diamonds Tender from the last remaining ore production next year.
According to Shmulik Polnauer from Leibish & Co, an Israel-based trader specialising in colored diamonds, the 2020 tender asking prices were 15 per cent higher than last year and that Leibish added “20 per cent and more” to its bids to ensure the company secured lots.
He told Rapaport, “As next year will be the last Argyle tender, we will bid on all stones, since the goods will become super rare, in high demand, and expensive.”

Era Of Pink Diamonds Comes To An End As Argyle Diamond Mine Set To Close End Of Next Year
For 30 years, jeweller John Calleija has been purchasing rare gems from Rio Tinto Group’s Argyle mine in remote Western Australia, home to 90 per cent of the world’s prized pink diamonds. On a recent rainy afternoon in New York’s Peninsula Hotel, Australia-based Mr Calleija studied some of the rarest pink and red stones through a magnifying glass as part of Rio Tinto’s annual pink diamonds…

Diamonds By ELOQ
A diamond (from the Historical Greek : ἀδάμας adámas, that means "unbreakable", "correct", or "unalterable") is one of the finest-recognized and most sought-after gemstones Diamonds have been recognized to mankind and used as ornamental items since historic times; some of the earliest references may be traced to India. Sizzling Diamonds Group USA is a wholesaler of Jewelry. The company provides merchandise akin to marriage ceremony rings, bangles, necklaces and extra. Independent teams such because the Gemological Institute of America grade diamonds for quality. That business commonplace means that a licensed, one-carat, princess diamond of a selected minimize, readability and colour should be almost identical in look no matter where you purchase it. Whiteflash gives an exceptional amount of knowledge for all their in-home diamonds. Together with an precise photo, you also get a Idealsope image and ASET picture (each of which present light performance) and hearts and arrows patterning (which reveals symmetry). It's also possible to view an HD video showing the fire and scintillation (i.e. how sparky it's). All this knowledge takes the guesswork out of your buy, so you'll be able to store with confidence.
In the event you were alive in 1957, and sufficiently old to enjoy Rock and Roll, you will in all probability remember the group, "The Diamonds" who had just launched their tremendous hit "Little Darlin'". For you which can be too young to remember - it was a time when the performers were blissful, enjoying themselves, respecting their fans, dressed appropriately and their lyrics could be understood. They did not really feel obligated to scream, eat the microphone, mumble inaudible lyrics or trash the set. Primarily based on analysis conducted, analysis of case research collected by the project workforce and after session with the non-public sector, the report concludes that the diamonds trade is subject to considerable vulnerabilities and dangers. The closed and opaque nature of the diamonds markets and the high worth of diamonds combined with a lack of information on this space on the a part of the authorities have left this business inclined to abuse by criminals. In London, the true De Beers, unable to stifle all the bogus entrepreneurs utilizing its name, decided to discover the potential market for funding gems. It announced in March of 1978 a highly unusual sort of "diamond fellowship" for selected retail jewelers. Each jeweler who participated would pay a $2,000 fellowship fee. In return, he would obtain a set of certificates for funding-grade diamonds, contractual kinds for "purchase-back" guarantees, promotional materials, and coaching in easy methods to sell these unmounted diamonds to an entirely new class of shoppers. The selected retailers would then promote loose stones rather than superb jewels, with certificates guaranteeing their worth at $4,000 to $6,000. The magma finally cooled inside these kimberlite pipes, leaving behind conical veins of kimberlite rock that include diamonds. Kimberlite is a bluish rock that diamond miners search for when in search of out new diamond deposits. The surface space of diamond-bearing kimberlite pipes ranges from 2 to 146 hectares (5 to 361 acres). Sure! That is practically the only option to inform the distinction between a mined and lab-created diamond. They are essentially the same factor, but pure diamonds have a higher resale value. Learn on for an additional quiz question. One criticism that has been levelled at Blue Nile previously is that customers of the positioning can't view prime quality photos for each of the diamonds that they offer on their web site. That is significantly necessary for shapes other than round, or for diamonds which are borderline clarity, where it's essential to have a look at every diamond to be able to decide whether or not it's ‘eye clear' or not. Thursday, October 12, 2017: New York. - Scott West by L.J. West Diamonds declares the Australian Pink Diamond Tour for the month of October to debut the largest assortment of beautiful fancy colored diamonds and diamond jewelry ever publicly exhibited in the Southern Hemisphere and can make its international debut at luxury jewellers Linneys Perth & Calleija Marina Mirage, Major Seashore, Gold Coast, Australia. The primary cease shall be in Western Australia at Linneys Crown Metropol showroom, the gathering can be unveiled for the very first time from 13 - 15 October, earlier than traveling to Sydney for personal viewings and to Calleija's Gold Coast location. These attributes include: the quality of their polishing, fluorescence, location of inclusion and its colour, and symmetry—more than 400 irregularities that each weighs on the worth of a polished pure diamond. Feedback on grading certificates can contribute to important variations in prices between diamonds with the same 4C characteristics. Diamonds can only truly grow to be a commodity if consumers understand the significance of these traits and their function in remaining value.
When it comes to loose diamonds, you won't find a better choice, better quality or higher worth wherever. If inside 15 days of your purchase, you discover a free diamond wherever in the United States with the identical specs, graded by the same gemological laboratory and at a cheaper price. MJ Christensen Diamonds will beat the price by 10% of the difference. If unable to beat the value, we are going to refund your money. First to sell diamonds online in 1999, Blue Nile provides high-quality certified Diamonds, Weddings and Engagements jewellery at Assured Finest Prices. Diamonds, Engagement Rings, Wedding Bands, High-quality Jewellery, Diamond Jewelry, Pearl Jewelry, Platinum Jewellery, Gold Jewellery, Silver Jewelry, intensive accumulation of the world's most interesting minimize diamonds and Vogue Jewelry are the appraisable and implausible assortment included at Blue Nile retailer. Since its institution the dominant mission of Blue Nile is to supply a better and enthusiastic on-line purchasing experience in addition to unprecedented high quality jewelry at exceptionally good value. Diamonds that reach the floor are sometimes blasted there in a short time, at speeds of 30 to 50 miles per hour by volcanic elevators referred to as kimberlites, Dr. Harlow said. If these elevators are too sluggish, however, that leaves diamonds susceptible to being dissolved in the fluid they are introduced up in. The sharp edges go first. Your Diamond Wallet is what permits you to transact with other users. It provides you complete and whole ownership of your Diamond stability and lets you send and obtain Diamonds. The pockets is installed in your laptop. Clearly my suggestion is to remain far-off from diamonds with this kind of treatment. Regardless of manufacturer claims that such a treatment is a everlasting answer, this method has been judged to be non-everlasting (as a result of the glass will change color) by a lot of gemological institutes. Lab-created synthetic diamonds have no resale worth. No jeweler will buy them again and if you attempt to promote them on eBay, you may get pennies on the greenback for it. So, from a price perspective, you would need to purchase the lab-created diamond at an enormous low cost to justify giving up the worth retention of pure diamonds. The one diamond cutter who I feel rivals the production quality supplied by Brian Gavin Diamonds is Paul Slegers of Crafted by Infinity, who markets their manufacturing by High Performance Diamonds and a small handful of different dealers… I appeared by means of their inventory and found one choice that's close to your most popular range of standards, however exceeds your price by just a bit, it's this 1.143 carat, F-color, VS-2 readability, Crafted by Infinity diamond with negligible fluorescence. There's been much buzz lately about conflict diamonds—diamonds which might be illegally sold or traded to fund violence in conflict-torn areas. Blue Nile maintains a zero-tolerance policy toward conflict diamonds, and works solely with established, reputable suppliers that track diamonds from mine to market. Choose a Blue Nile coupon code to save on a glowing stone that's each visually beautiful and socially responsible. To make a profit, buyers should at some time discover patrons who're keen to pay extra for his or her diamonds than they did. Here, nevertheless, buyers face the same problem as those making an attempt to sell their jewellery: there isn't any unified market during which to sell diamonds. Though sellers will quote the costs at which they are prepared to sell funding-grade diamonds, they seldom give a set price at which they're willing to purchase diamonds of the same grade. We are engaged in manufacturing, exporting and supplying supreme quality Natural Diamonds that's cut and polished by utilizing newest expertise. Our supplied diamonds are available in a number of engaging colors, shapes & sizes for our shoppers to select from. The diamonds offered by us are tested by our quality examiners for making certain their flawlessness. Apart from this, clients can avail your complete range at all-time low costs within stipulated period of time. Winsome Diamonds and Jewelry COMPLIANCE CERTIFICATES FOR THE 12 MONTHS ENDED THIRTY FIRST MARCH, 2017. At Ok Rosengart, we worth the belief you place in us. Our promise to you is to ship the finest pure loose and melee diamonds within the trade. Each time. With out worry, and with out compromise. Lab-grown diamonds are chemically, bodily and optically similar to mined diamonds. Scio Diamond's know-how affords the flexibility to produce lab-grown diamonds in size, colour and high quality mixtures which are rare in mined diamonds. The Kimberley Course of was developed to monitor the trade in tough diamonds and stop their being used to fund violence. Earlier than exporting, rough diamonds are certificated by the government of the country of origin. Some international locations, corresponding to Venezuela, aren't occasion to the agreement. The Kimberley Course of does not apply to local sales of rough diamonds within a rustic. Presently lab created diamonds account for roughly 2% of total diamond gross sales in addition they value up to 35% lower than natural diamonds. More than a whopping ninety% of diamond engagement rings use pure diamonds. Artificial diamonds have discovered a subject within the industrial marketplace and have been used for many different industrial applications as they're made to final. They will face up to huge ranges of radiation they're used in engineering, drugs and in a variety of reducing instruments. Lab grown diamonds might someday find a area of interest in nice jewellry however it might probably never replace or evaluate to licensed GIA diamonds and all of the emotion, years of history, romance and love that's related to pure diamonds.

Solely the best high quality diamonds enter the jewelry industry, with the remaining diamonds getting used industrially in equipment. I don't really know learn how to reply this to be sincere as purchasing nightmare may be extra applicable. I can solely hope that the diamonds they promote have extra readability than their web site however contemplating you solely see a tiny image of them I will not maintain my breathe. I am used to dealing with prime corporations who supply outstanding buying experiences proper throughout the board. I'm not knocking Blue Nile's products per se however the person experience their e-commerce web site delivers is abysmal at finest. My engagement ring was purchased by means of Blue Nile. It is absolutely beautiful and the diamonds are so good. We plan on going by them for my wedding ceremony band as properly. Type 1-A diamonds are excessive in hydrogen content material.

Throughout the recession of the mid-970s, it had to make use of a big portion of its money reserve to purchase diamonds from Russia and from newly impartial international locations in Africa, so as to protect the cartel arrangement. Because it added diamonds to its stockpile, De Beers depleted its cash reserves. Moreover, in 1980, De Beers discovered it mandatory to purchase again diamonds on the wholesale markets in Antwerp to prevent a complete collapse in diamond costs. When the Israeli banks approached De Beers about the opportunity of buying back the diamonds, De Beers, probably for the primary time for the reason that depression of the 1930s, discovered itself severely strapped for cash.

Many of the important industrialized nations are actually capable of produce synthetic diamonds for industrial use in factories.

A diamond with a perfect crystal lattice made totally of carbon could be completely colourless. In reality, however, all diamond crystals comprise atomic impurities and structural imperfections. We name these 'colour centres' as a result of they're chargeable for the color of a diamond. The commonest atomic impurity in a diamond is nitrogen. Based mostly on the presence of this atom within the diamond lattice, one can classify diamonds into two primary teams. Type I diamonds contain a better level of nitrogen, whereas kind II diamonds include virtually no nitrogen. The spherical brilliant is the preferred diamond form and reduce, with many sources citing that three-fourths of the diamonds bought are of this sort. This may very well be for several causes. Most rough diamonds are shaped such that two round brilliant diamonds might be reduce with the least amount of crystal lost. Additionally, the round good and the princess shape (which is the next hottest) are common as a result of they replicate gentle greatest and are thus the most sensible for his or her size. Crystals that aren't symmetrically formed or have awkwardly situated inclusions are often minimize into what known as a "fancy minimize" or a lower apart from a spherical sensible. Gems will be grown with the HPHT method, using much less nitrogen, but are nonetheless typically a yellow, inexperienced, or brown hue resulting from small amounts of the chemical. Alternative development recipes make use of boron, which produces blueish stones, nearer to colorless. Even the clearest gems however are straightforward to differentiate from pure diamonds utilizing only a black light. After UV illumination, they will phosphoresce, or glow with an intense greenish hue. Generally a easy magnet will do: these stones can be magnetic attributable to trapped impurities, something by no means seen in clear natural diamonds.
