Ex. Steve Pullman
A real nice spherical aggregate of small, bladed crystals of Colemanite rest upon much smaller Colemanite crystals included with Clay which rest atop orange/tan colored, rounded Calcite crystals. The crystals of the rounded aggregate have a high, sparkly luster and are a light gray color with a slight hint of pale blue/green.
Condition: Fairly Good
Flaws: The Calcite is fairly heavily bruised. There is some minor bruising on the Colemanite.
