Prehnite finger cast after Anhydrite with CalciteA beautiful, undamaged, isolated finger shaped cast of Prehnite after Anhydrite with lovely soft luster, gemminess and light green color sits among several spherical aggregates of Prehnite which are associated with a ridge of off white color scalenohedra of Calcite sitting along the edge of the specimen. The piece is in great shape for the material and truly looks better in person as it was somewhat difficult to photograph. The Prospect Park Quarry is

The Alice Mine is one of the most classic of all the Colorado localities for Chalcopyrite

rich blue color prism of Aquamarine from one of the more obscure localities for the material

Ludlamite associated with Quartz is also incredibly rare

This piece hosts several white/cream-colored botryoidal aggregates of Anhydrite which are sitting on white Quartz matrix with accenting pink Rhodochrosite and minor sulfides

so collecting and obtaining specimens will become very difficult in the future

and those specimens don't hold a candle to the stunning specimens from the Sunnyside

glowing yellow color hexagonal prisms of Mimetite with a fine resinous luster are covering the underlying oxidized matrix

Only a tiny bit of damage on the back

which is very good for the material

you can really see the color and gemminess come through
