9.83 ct Diaspore & Diamond 18K Ring

Diaspore is a color-changing gemstone.  We chose rose gold because it makes this gemstone 'pop'.  When it's green it is a complementary color and when the gemstone changes to peach the rose gold accentuates it. We took this beautiful gemstone cut perfectly in a large oval shape and designed an 8-prong rose gold setting with (approximately) .66 carat of round diamonds under the gemstone in swirls and on the band. Of the photos listed four are in direct sunlight (gemstone is green) while one photo is in incandescent light (gemstone is reddish peach).

What exactly is a "Diaspore”?

If you are familiar with Alexandrite, you know that there are color changing gemstones.  These gemstones, depending upon whether the light source is incandescent, fluorescent, halogen, direct sunlight, etc. changes the color of the gemstone. In the gem trade, color change is a rarity in and of itself. Alexandrite, East African Color Change Garnet and some rare Sapphires are all color change gemstones and we rarely see them. All of these gemstones are rare - they are true color changing - not color shifting. Diaspore, which is mined in only one place (the Anatolia region of Turkey) is truly an exotic gemstone that you will treasure forever. In some of the photos you will see the gemstone trying to change color you'll see portions of the gemstone peach, while other parts are green. The color change is more dramatic in person.
