Item Description

This is one of the most rare and beautiful species in the entire mineral world, and arguably, the most amazing 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 specimen features several small (3 mm), exceptionally rare, lustrous, gem/gemmy, beautiful blue green color, "classic", twinned, crystals of the great phosphate Phosphophyllite associated with tan Siderite sitting on massive, deep reddish-black Sphalerite matrix. Please note that specimens of Phosphophyllite simply are NOT seen in today's market, in ANY format, and to find MATRIX specimens is almost impossible. I've photographed the little "butterfly" twins under the microscope to better illustrate their great form.
