Calcite with Chalcopyrite
Out of stock
A rather large piece with several pieces of loose breccia cemented by calcites and on which have formed crystals on the front and back, many doubly terminated. The prismatic central crystal is 8.5cm and nearly 2.5cm thick. Above it is a 7.2cm doubly terminated crystal! Remarkably, very few crystals have any damage and there are at least a hundred. One thick crystal is broken near the base at the top central-left. This could fairly easily be removed. Ex Kenny Gay collection.
Locality: Milliken Mine, Viburnum Trend, Reynolds County, Missouri
