Descripción: Quartz Locality: Siglo Veinte Mine (Siglo XX Mine; Llallagua Mine; Catavi), Llallagua, Rafael Bustillo Province, Potosí Department, Bolivia (Locality at mindat.org) Size: 12.9 x 8.8 x 7.3 cm. The Siglo Veinte mine is one of the most impressive Bolivian localities. It is the type locality for many "best in the world" species, and it even produces some amazing specimens of common species like Quartz. The Japan-Law twin Quartz specimens are well known in the mineral world and this piece is a great example of that material. The specimen it self hosts dozens if not hundreds of absolutely water-clear, razor sharp, highly lustrous, prismatic color Quartz crystals, plus three Japan-Law twins. Unfortunately, two of the twins are not complete, but one of them is (close-up).
