This small hand specimen contains at least 15 Sphalerite crystals. They are generally in good condition, though 4 or 5 crystals are damaged or broken. The 2 or 3 largest crystals are heavily intergrown and warped, so that the viewer cannot discern one from another. It would appear that these crystals measure at least 0.5" (1.3 cm) in diameter, however. The other crystals show good tetrahedral or octahedral form, though they too are often intergrown with each other. Several are also twinned, further adding to the confusion. Most still have well-defined edges and lightly patterned but clean faces, however, and all have the dark brown color and adamantine luster that are standard for their species. They are so dark in color that they are essentially opaque. Most of the crystals rest on a bed of crystalline dolomite, but some rest on the pale gray limestone base rock.
