This is a rare and really beautiful color-changing gemstone - the exotic diaspore, (a.k.a. Zultanite).
This ring has approximately 12 carats total weight of fancy scissor elongated cushion cuts with 4 matched gemstones. What makes these gemstones so beautiful is their sparkle - the 4 gemstones are highly dispersive, and have rainbow sparkle. Then, as a bonus, this gemstone will change color from a kiwi green to a salmon pink in incandescent and candle lighting - like an alexandrite.
We set the 4 matching gemstones vertically, in a color-complementing rose gold setting. Incredible one-of-a-kind beauty.

What exactly is a Spinel?
Spinels are 100 times rarer than Rubies and Sapphires, yet less expensive (because most of the world still doesn't know about these rare beauties!). The minerals that comprise Spinel are very similar to Rubies and Sapphires (Corundum), in fact, Spinels are always found in the mines growing right next to Rubies and Sapphires. Spinels are hard and sparkly and make fantastic gemstones in jewelry to be worn everyday - with a lot of Bling! They have been mistaken for Rubies and Sapphires for centuries - they are even in the Crown Jewels of England, i.e., The Black Prince's Ruby - which is actually a large red Spinel. They come in a wide range of beautiful colors, just like sapphires. They are also similar to Sapphires in hardness (8 on the Mohs' Scale) yet half the price. This is a real find! We bought this gemstone from a connoisseur collector who purchased it from the mines in Ceylon - for your collection!
Spinel is a good candidate for the title of “History’s Most Underappreciated Gem.” Some ancient mines that supplied gems for royal courts from Rome to China produced spinel, but it was usually confused with better-known stones like ruby and sapphire.
In ancient times, the mines of central and southeast Asia yielded exceptionally large spinel crystals. These fine stones became known as Balas rubies, and some of them were the treasured property of kings and emperors, often passing through many hands as spoils of war. As a result, some of the world’s most illustrious “rubies” are actually spinel.
One of the most famous examples is the so-called “Black Prince’s ruby.” This historic crimson-red gem is set in England’s Imperial State Crown and displayed in the Tower of London. Smoothly polished and roughly octagonal in shape, it was probably mined in the mountains of Afghanistan. It first appeared in the historical records of fourteenth-century Spain, and was owned by a succession of Moorish and Spanish Kings before Edward, Prince of Wales—the “Black Prince”— received the stone in 1367 as payment for a battle victory.
Since then, many other English monarchs—including Henry VIII—have cherished the gem. It’s outlasted them all, surviving fires, attempted theft, and World War II bombing raids, to become—with the Koh-i-Noor diamond—one of the centerpieces of England’s Crown Jewels.
Another large spinel in the Crown Jewels, the “Timur ruby,” weighs over 350 carats. It, too, has a checkered history. Several Persian inscriptions carved into the gem testify to its age.
Modern technology hasn’t helped spinel’s confused identity as far as the general public is concerned. This is due largely to the widespread use of synthetic spinel as an imitation for many other gems. Most customers aren’t even aware that there’s a natural version of the stone. (Source: GIA)
