Cabochon véritable en lapis-lazuli, coussin bombé de 12 mm x 10 mm, de haute qualité

Lapis Lazuli has been mined in the mountains of Afghanistan for more than 6,000 years — these mountains are the world's oldest known commercial gemstone mines. Prized throughout antiquity as much as sapphire, Lapis Lazuli's vivid blue was historically ground to produce pigment before synthetic dyes existed. Technically a rock rather than a single mineral, Lapis Lazuli is composed of varying amounts of lazurite, pyrite, and calcite. Lazurite delivers the signature blue color, calcite produces white veining, and pyrite appears as gold flecks. The finest quality Lapis Lazuli displays a pure, vivid royal blue with no calcite and little to no pyrite present — exactly what this cabochon offers.

This calibrated 12mm x 10mm cushion buff top cabochon is a high-quality stone with deep, rich blue color and no treatments applied. It makes an excellent alternative for a December birthstone setting. Clean with warm, soapy water only; avoid ultrasonic and steam cleaners.
