Kyanite mineral specimens collected from Ogilby, California. Kyanite is an aluminosillicate mineral; it has a bladed, fibrous or columnar crystal habit and typically has an eye catching blue colour. We supply a rarer black variety of kyanite but other green, orange & pink varieties are known. These kyanite minerals stand proudly, mounted (attached with glue) on a polystyrene base within a 1.5" x 1.5" card tray, information label attached. These specimens would be suited for geologists, collectors or simply those interested in mineralogy looking for an attractive display piece.
