Harmony Quartz Floating Cube

Commonly mis-named as “sphalerite”, it’s actually a brecciated combination of possible materials including limestone, calcite, jasper, chalcedony and sparkly drusy quartz. (That's a mouthful!) With help from other members of the crystal community, I coined the term "Harmony Quartz" to use instead of the incorrect label. 2.5"x2.5"x2.5". From China.
