A large size cobalt spinel from a relatively small find in the Mahenge Tanzania. This spinel weighs 1.50 Carats and is cut in an oval that measures 7.35 x 5.97 x 4.45mm. The color shifts between blue and slightly purplish blue in some lighting. Eye clean clarity only adds to the rarity of this spinel. A true collectors gem that can also be mounted into a piece of beautiful jewelry! Comes with a GIA report that verifies it is cobalt spinel.
