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 1.3 cm Japan-Law twin Quartz along with a additional prismatic Quartz crystals on matrix. The overall aesthetics are good, and one side of the twin is just slightly contacted. Siglo XX is one of the most impressive Bolivian localities hands down for the plethora of species and unique assemblages. It is the type locality for many "best in the world" species as well, and it even produces some amazing specimens of common species like Quartz. Valued at $600. Enjoy!
