Description

Description

A unique three dimensional calcite coated dolomite stalactite retaining its original sales label from a well known mineral dealer Prosper J. Williams. I have held this outstanding Tsumeb specimen back from a number of years since it was the most notable as well as attractive specimen in the collection that I acquired. 

Measuring 4.8cm in height this vertical dolomite stalactite structure is completely overgrown by literally hundreds of water clear calcite rhombs extending outwards evenly flush with one another creating an impressive sparkling highly lustrous skin.

Featuring prime aesthetics with a bulging spheroidal termination that lies high above the broad base.

A true work of natural art that you will not likely see again in a superb condition.

The specimen glows bright pink under shortwave UV.
