Welcome to our Black Kyanite crystal page.
|This is a new item we acquired from an estate. Kyanite crystals have a variety of unique features. The crystal itself has a dual hardness. Cut along the axis of the crystal, it is extremely soft, however when you turn it at a 45 degree angle from that axis, the crystal is almost as hard as a Diamond (7.5+ on the mohs scale). Many of these pieces have iron and garnets. Kyanite gemstones also have a perfect cleavage, meaning it breaks cleanly and easily. These attributes make the stone quite a challenge for faceting and cutting. Simply click any photo for expanded view and to be taken to a secure order page.|
