Csarite a part of the National Gem Collection

In 2014 two large, rare color-changing csarite gemstones were donated to the Smithsonian Institution’s National Gem Collection, thanks to Milenyum Mining Ltd.

The Dubai-based miner donated the stones, a 44.48-carat faceted oval-shaped csarite and a 159.33-carat cat’s eye cabochon csarite, at the American Gem Trade Association’s GemFair.
Csarite, a naturally color-changing diaspore, is mined at its one global source, the Anatolia Mountains of Turkey. Milenyum is the only company that mines the gemstone.

Typical loss cutting rough Csarite is 98 percent. This makes large gemstones extremely rare and valuable.
“To our knowledge, currently there are fewer than 20 faceted csarite gemstones in the world that have a weight of 40 carats and above. Given the rarity of this unusual gem, we feel the Smithsonian’s National Gem Collection is a fitting home for two of the few examples available in this size and quality,” said Milenyum Mining President Murat Akgun.
The National Gem Collection is housed at the National Museum of Natural History in Washington. It consists of over 350,000 mineral specimens and 10,000 gemstones, including the Hope Diamond, making it one of the largest of its kind in the word.

A 121.65-carat pear-shaped rarity was cut from a recovered rough stone of approximately 430 grams.
