This is spectacular - a color changing Sapphire that changes from deep gray/blue/green to purple to pink, and is totally natural and unheated/untreated. This is a certified natural sapphire, mined in Tanga, Tanzania. In indoor lighting, this sapphire is a pinkish/grayish/purple; in the sunlight it is a bluish/grayish/teal - with the same beautiful color changing physical properties as Alexandrite. In incandescent lighting and candlelight, it is a beautiful pink color. Most color change sapphires change from blue to purple and are rare. The colors this gemstone exhibits are very rare. Unheated/untreated color change sapphires are very, very rare. This sapphire is truly unique and spectacular. So spectacular, in fact that we put it in a setting surrounded by 1.5 carats of colorless, VVS clarity full-cut diamonds in 18K yellow gold.

This is a rare and spectacular sphene. Its origin is Madagascar, and due to its chromium content, the color is a magnificent green with major rainbow sparkle. The color for sphene is rare, and usually sphenes are included, but this one is eye clean and has major light prismatic dispersion. Also known as sphene titanate, this is one of the world's most spectacular gemstones. This gemstone has a very high refractive index, and a dispersion (prismatic effect) that far exceeds diamonds. It is commonly referred to as a "Christmas tree flash". Bright sunlight gives you the 'rainbow' color flashes. This gemstone's rare clarity, color saturation and size (above 1 carat is rare), make it one of the rarest of the sphenes. We designed this setting that complements sphene's color and sparks with a 2-sided halo around the gemstone [one with large diamonds that face up, one with smaller diamonds that are at a 90 degrees]. We added a satin finish to draw the eye to the sparkling diamonds and magnificent sphene! Made by women for women. Gemstone Natural Chrome Sphene...
