Three individual octahedral crystals of deep cobalt blue Spinel. These were first discovered in 2001 and are found mostly of industrial quality.
Though they don't get very large, the color is spectacular. Translucent to transparent. Sizes range from 9mm wide to 5mm wide. Studies ahve shown these
to be very high in Zinc and could be labelled as Gahnite.
