  • 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. A truly one-of-a-kind gemstone ring from California Girl Jewelry...
