I have had this cobalt spinel in my personal collection for many years. It weighs 1.16 Carats and is precision cut in a pear shape that measures 8.56 x 6.21 x 3.32mm. The blue color on this spinel is due to cobalt content which makes for one very rare, beautiful gem. What adds to the rarity is the clarity on this one, it's loupe clean! This comes accompanied with an origin report from the GRS stating cobalt content and an origin of Vietnam.
