Orange kyanite from Tanzania

Abstract

Kyanite derives its name from the Greek word for blue, due to its typical color. Gem-quality green kyanite has also been seen (e.g., Winter 2001 GNI, pp. 337-338), and colorless or yellow varieties have occasionally been faceted. Recently, however, orange kyanite has appeared in the gem market. The material was mined at Loliondo, Tanzania, near the area that recently produced fine crystals of spessartine (see, e.g., Spring 2008 GNI, pp. 76-78).
