{"product_id":"round-kyanite-cabochon-20mm","title":"Round Kyanite Cabochon","description":"\u003cp\u003eKyanite takes its name from the Greek word \u003cem\u003ekyanos\u003c\/em\u003e, meaning \"dark blue.\" This distinctive gemstone closely resembles sapphire and is widely used as an alternative, particularly in beads and cabochons. Kyanite generally ranges from blue to green, with traces of chromium and iron responsible for its characteristic color. Notably, kyanite possesses different hardness values depending on crystal direction—a property unique among gemstones. These round cabochons display a translucent medium blue with a soft, milky sheen and have received no treatments.\u003c\/p\u003e\n\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTranslucent medium blue color with a milky sheen\u003c\/li\u003e\n\u003cli\u003eNatural kyanite—no treatments applied\u003c\/li\u003e\n\u003cli\u003eRound cabochon cut\u003c\/li\u003e\n\u003cli\u003eUnique anisotropic hardness varies by crystal direction\u003c\/li\u003e\n\u003cli\u003eVisually similar to sapphire; popular for use in cabochon and bead settings\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003eStone Type\u003c\/th\u003e\n\u003ctd\u003eGenuine Kyanite\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCut\u003c\/th\u003e\n\u003ctd\u003eRound Cabochon\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eColor\u003c\/th\u003e\n\u003ctd\u003eTranslucent Medium Blue with Milky Sheen\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eTreatment\u003c\/th\u003e\n\u003ctd\u003eNone\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003cth\u003eCare\u003c\/th\u003e\n\u003ctd\u003eClean with warm, soapy water only; avoid ultrasonic and steam cleaners\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eAvailable Options\u003c\/h3\u003e\n\u003ctable\u003e\n\u003ctr\u003e\n\u003cth\u003ePart #\u003c\/th\u003e\n\u003cth\u003eStone Size\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e9CB-RO-001-BL-20MM\u003c\/td\u003e\n\u003ctd\u003e20mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eNotes\u003c\/h3\u003e\n\u003cp\u003eDue to kyanite's variable hardness across crystal directions, handle finished cabochons with care during setting.
