This is a very interesting specimen as it is the only piece from the lot that formed a complete crystallized vug that remained in tact after extraction. This is from a relatively new find at Machacamarca, which is better known for its Bournonite specimens. This piece features a sharp, lustrous, gemmy crystal measuring 1.3 cm in length. There are several smaller, but equal quality crystals in the vug as well. It looks much better in person than the pictures would indicate. It is a unique Bolivian specimen of this rare phosphate species. 6.1 x 5.2 x 3 cm
