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. Lettered A-G matches from front to row left to right, and then back row left to right. From China.
