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 beautiful, very gemmy, colorless Japan-Law twin of Quartz measuring 5.3 cm across along with several prismatic Quartz crystals and minor black Cassiterite on massive Quartz matrix The overall quality is very good. 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. Enjoy!
