Sparkling natural diaspore gemstone is set in solid sterling silver pendant, and is accented with a genuine white zircon. Diaspore is a natural gemstone, mined in Turkey. This incredible VVS clarity diaspore exhibits strong color change; it measures 7.25 x 6 mm, and weighs 1.3 carats. The natural zircon account is also a mined gemstone, not to be confused with man made cubic zirconia, which is an entirely different material. An OPTIONAL 18 inch solid sterling silver baby-box chain is available with purchase. Not for use on babies or children.
