Introducing the "Mixed Minerals" gallery which is part of our New Additions galleries. This gallery contains mineral specimens for sale including aurichalcite, fluorite, microlite group - pyrochlore supergroup, wulfenite, and zircon and more from places like Mina Ojuela, Mapimi, Durango, Mexico, Mont Saint-Hilaire, Rouville Co., Quebec, Canada, Tsumeb mine, Tsumeb, Namibia.

Aurichalcite

with Calcite - #AH54896

Cabinet specimen with large pockets of bluish green sheaf-like crystal bundles in radial sprays to 3mm. Within these pockets are 2-6mm Calcite crystals some of which are waterclear. Some of the Aurichalcite sprays are completely engulfed by clear Calcite to the point at which it terminates atop of the Aurichalcite termination - and it's really cool. One of the photos has a little tiny sprays no more than 0.75mm of I think Hemimorphite.

Yellowish brown excellent crystals of tabular Wulfenite with beveled edges. The crystals reach 11mm and are sharp and pristine. The backside of the specimen is covered with snow white Calcite or Dolomite and near the sides bow-ties of light yellow Mimetite are seen.
