Description

This superb three dimensional floater is from an intermediate find that produced small numbers of the most aesthetic arrangements featuring isolated large prismatic crystals-here a twin psm stands elegantly exposed in the widest part of the vug surrounded by a mass of botryoidal plancheite casts. The casts exhibit well defined rhombohendral crystal forms of the calcite that were once there.

The significant increased weight of this material sets it apart from all previous and later finds telling of its less decayed nature, when tapped with your fingernail it makes a metallic ring to it.

The black exterior shell provides a great contrast boosting the turquoise color significantly.

Damage free.
