Microcline (var: Amazonite)Here we have a well formed, sharp, good blue green color prismatic crystal of Amazonite with a slight "white cap" termination. The left edge of the crystal has a contact, but overall, the piece is in good shape. From the collection of Willard W. Wulff (1904 1998) of Colorado Springs, Colorado, a prominent figure and collector of Colorado minerals. Wulff was one of the founding members of the Colorado Springs Mineralogical Society in 1936.

and when it arrived

These are true Alpine classics

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

It is very difficult to obtain any specimens of this incredibly beautiful and rare phosphate

or a suite of Bolivian specimens

A very impressive and certainly hard to find GEM quality Cassiterite specimen from the famous Viloco Mine

Superb condition overall

This specimen is not only an impressive

Specimen # BOL711B146

NOTE: Even though Calcite is widespread in the world

I obtained this piece directly from the miners at Porco a few months ago
