Description
A deep purple octahedral Spinel crystal on Carbonate Marble matrix, which is very typical for the metamorphic geological environment of Mahenge in southern Tanzania. The main crystal, a Spinel with stair-like growth patterns measures 2.5 cm wide. It is gemmy with a great vitreous luster. It is associated with smaller brown Spinel with a more rounded habit. Very beautiful piece, almost in gemstone quality, and very characteristic for the locality.
