Australian Mintabie Opal & Diamond 18K Ring

  • Rare Chrome Sphene & Diamond 18K Ring
    Located in Mill Valley, CA
    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...

  • Rare Unheated Color-Change Sapphire & Diamond 18K Ring
    Located in Mill Valley, CA
    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.

  • Australian Natural Untreated 17.53ct Pipe Opal Diamond Cocktail Ring 18K Gold
    By Renata Bernard
    Located in Sydney, AU
    Mysterious and magical, “Deep Love” opal ring is evocative of an ocean dive on a lazy summer day. A superb 17.53 carat pipe opal from our own mines in Jundah-Opalville is the star of this bold and impressive cocktail ring. The unusual 18K yellow gold setting with its flash of twinkling diamonds make this piece is something special. Designed by Renata Bernard. The gemstone at the centre of this opal ring is an Australian pipe boulder opal from Opal Minded's own opal mines in Jundah-Opalville in Queensland. This gem is particularly exciting for its size and brightness. Jundah-Opalville opal fields are known in the opal industry for the outstanding quality of pipe opal they (occasionally) reveal. Pipe boulder opal is an organic-matter-replacement opal that forms in iron-ore bearing rocks. Its distinctive quality is the "play of colour" present in mostly translucent gem material, a phenomenon which manifests in opal's colours shifting and changing as the gem moves. Australian opals, in general, are the quality benchmark for the world family of opals owing to their durability and beauty. This particular opal is transparent and attached naturally to the host rock in which it was found. Outstanding in size and quality, its play of colour is suspended in the otherwise transparent opal...
