Water clear Calcite crystals with a high, glassy luster, smooth faces and beveled edges. Many of the Calcite crystals have included Marcasite and a few have Marcasite crystals on the surface. Several of the crystals exhibit attractive rainbow diffractions which are not well depicted in the photos (in fact, the specimen is in general more attractive than the photos). The crystals are colorless but lie atop another layer of massive Calcite which is a light yellow/beige color.

Condition: Good

Flaws: One of the larger crystals is bruised and a few others have internal cleaves.
