A fine and large size (for the location, or anywhere for that matter) electric blue cobalt spinel crystal, from Loc Yen, Vietnam. Cobalt spinel is the rarest form of spinel, found less than five locations world wide. In reality the color is just a tinge lighter than pics indicate. This wonderful specimen we were able to obtain on our trip to the mine in Vietnam last year, believe me, (or check the net) these are not easy to come by, particularly in any size above very small!!
LOC YEN, VIETNAM.
