Calcite with Hemimorphite (ex Tom Campbell Collection)

Item Description

A hard to find display specimen of Calcite from the world famous Ojulea Mine. The piece features sharp, well-formed, stark white colored rhombohedra of Calcite measuring up to 2.8 cm which are associated with heavily iron-included groups of Hemimorphite which have a rich orange-red hue with good lighting. The crystals appear to be sitting on soft grey colored semi-botryoidal Goethite on gossan matrix. Very attractive and a great piece to add to any Calcite suite or a collection of Mexican minerals. No damage that I can see, save a small spot on the back where it was removed from the pocket wall. Valued at $1,250. From the worldwide collection of Tom Campbell.
