Libethenite (classic material)

Item Description

The well-known Miguel Vacas Mine in Portugal is famous for producing excellent specimens of various phosphate species, including some of the finest specimens of Libethenite in the world. While the crystals are often small, they are still some of the finest examples of Libethenite, showing superb textbook crystal form. This piece is filled with dozens of small (about 2 mm), very sharp, highly lustrous, deep black-green colored bi-pyramidal crystals of Libethenite on matrix. The vast majority of the crystals are undamaged. A wonderful example of these beloved and fine quality Libethenite specimens. From the collection of Vasco Trancoso, a medical doctor and prominent mineral collector from near Lisbon, Portugal (https://www.mindat.org/user-11954.html). He assembled his mineral collection over the course of 60 years, and built a fine worldwide display collection that we recently purchased.
