Phosphophyllite twin (Bancroft & Larson Coll.)

Item Description

This is one of the most rare and beautiful species in the mineral world, and arguably, the most highly sought after phosphate species extant. It is not only highly sought after, but in recent years has been dubbed the "Holy Grail" of mineral species for collectors. Many collectors and dealers alike treasure this species for its immense scarcity and immeasurable combination of form and color. This TWINNED MATRIX crystal specimen features an exceptionally rare, GEMMY!, incredibly beautiful blue green color, crystal of the great phosphate associated from the most well known locality for the species. Please note that specimens of phosphophyllite from the late 1950s to early 1960s Cerro Rico finds simply are NOT seen in today's market, in ANY format, and even though this piece has both terminations contacted, it's not nearly as distracting as it would be for other species. This is a worthwhile specimen for somebody interested in owning a piece of this very desirable and rare phosphate, but please note it is not a top shelf collector specimen. It is, what it is. Ex Pete Bancroft to Bill Larson in the 1960s. Valued at $2000-2250.
