Sapphirine hibonite with some graphite in aWe are selling off our stock: Sapphirines of this quality have not been found for several months. The matrix is very hard and often adheres strongly to the crystals, so damage from exposing the crystals or formatting the steps is common. Only rarely do the crystals break away from the matrix undamaged. This very small sapphire has very beautiful surfaces. It's missing an edge on the back.
