|The worlds of jewellery and art are even more intertwined than those of art and fashion. From jewellers taking inspiration from artists to artists themselves turning their hands to goldsmithing, the two fields have a symbiotic relationship. Until now, no modern art museum has ever staged a significant jewellery exhibition. 'Medusa: Jewellery and Taboos' is featured at Paris’s Museum of Modern art.|

|In 2014 two large, rare color-changing diaspore 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 diaspore and a 159.33-carat cat’s eye cabochon diaspore, at the American Gem Trade Association’s GemFair.
|Diaspore is a naturally color-changing gem, and is mined at only one source, the Anatolia Mountains of Turkey. Milenyum is the only company that mines the gemstone.|
Zultanite and Csarite are trade names.
| Diaspore is a durable gemstone with a hardness of 6.5 – 7 on the MOHS scale. Since Diaspore has perfect cleavage in one direction it can be difficult to cut because parts of the stone will cleave off.|
Typical loss cutting rough diaspore 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.

|New York-based Paul Forrest Co. is bringing jewellery to life with a diamond-encrusted necklace that’s built with its very own beating heart. The action of the beating heart is controlled by a mechanical movement similar to that found in a watch. |
The mainspring, which is wound by a tiny key, powers a chain of trains, levers and wheels that drive the beating halves in the pendant, slowly moving back and forth to create the illusion of a beating heart.
|The movements are all made in Switzerland, with price points ranging from $19,000 to $45,000.|
Customers can personalize their pendants with a selection of diamonds or gemstones.

|Seven jewels and two watches were placed on auction on January 7 along with 120 other items. In terms of material they were unremarkable, low-karat gold set with diamonds and gems with seemingly little significance. The designs were unconventional. Yet they commanded significant sums. That’s because the jewels were either owned or gifted by Elvis Presley.|
Presley, who died in 1977, is regarded as one of the most significant cultural icons of the 20th century.

|Spinel is the magnesium aluminium member of the larger spinel group of minerals. It has the formula MgAl2O4. Balas ruby is an old name for a rose-tinted variety.|
After the 18th century the word ruby was only used for the red gem variety of the mineral corundum and the word spinel became used. "Balas" is derived from Balascia, the ancient name for Badakhshan. The Badakshan Province was for centuries the main source for red and pink spinels.

|Spinel is most famous for its deep red variety that closely resembles ruby. The two gemstones can be very difficult to distinguish. Until the late 19th century, there was no distinction made between ruby and red spinel, as they look identical and are found in the same localities. Many famous old "rubies" were discovered to be spinel.|
Mining in Afghanistan has a history over 2,000 years. Afghanistan's ruby/spinel mines were mentioned in the writings of many early travelers. The Badakhshan mines were of great importance during the period from 1000–1900 AD. They were the source of many of the finest early red spinels in gem collections around the world.
