This beautiful blue. This hard shine has a Mohs hardness of 8. "Blue spinel" does not necessarily mean "cobalt spinel"; anything with a confirmed cobalt band is called "cobalt spinel". This is a Vietnamese cobalt spinel with a distinctive neon color.
Color-shifted cobalt spinel from Vietnam that was purchased directly overseas and cut by skilled craftsmen in Bangkok. Among the Vietnamese cobalt spinels, it is loose and of high quality with particular attention to color and cut.
