Item Description
The Japan-Law twin Quartz specimens from this mine are well known in the mineral world, and this piece is a nice example of said material. The specimen hosts a pair of beautiful, very gemmy, colorless Japan-Law twin Quartz crystals mixed in with dozens of prismatic Quartz crystals on matrix. The largest Japan-Law twin measures 2.6 cm across. The overall quality is very good, and the assocaited white Wavellite and metallic pale golden Marcasite makes for a beautiful color contrast. Siglo XX is one of the most impressive Bolivian localities hands down for the diversity of minerals and the quantity of specimens produced for over a century. It is the type locality for many "best in the world" species, and it even produces some amazing specimens of common species like Quartz. Valued at $1500. Enjoy!
