Rare from Morocco, this is a gemmy, brilliant, lustrous yellow single crystal. When backlit, it glows a lemon yellow color! As a sphalerite single crystal, it has shape, color, and location value going for it. It is complete all around. A very rare find in such quality. Interestingly as a bonus, the surface looks smooth but on extreme magnification has a patterned, triangular like pattern within the seemingly smooth faces.
