About Gahnospinel
Gahnospinel is an intermediate spinel composition between gahnite (zinc spinel) and spinel (magnesium aluminum oxide), typically displaying dark blue to greenish-blue colors with a vitreous luster. It occurs in metamorphic and igneous environments, often associated with zinc ore deposits, and is found in localities including Sri Lanka, Burma, and Australia. Gem-quality transparent material is faceted into attractive blue stones prized by spinel and collector enthusiasts.
