Quartz (Japan-Law Twin) with Wavellite

Item Description

Siglo XX is one of the most impressive Bolivian localities hands down. It is the type locality for many "best in the world" species, and it even produces some amazing specimens of common species like Quartz. Japan-Law twin Quartz specimens are well known in the mineral world, and this piece is a great example of said material. The specimen hosts several absolutely water-clear, razor sharp, lustrous, prismatic, colorless Quartz crystals, which are associated with white botryoidal Wavellite, but the most important apsect of the piece is an attractive Japan-Law twin measuring 4.2 cm across on the side of the specimen. I've drawn a few red lines on the photos to actually show the defnition of some of twins the better, as the piece is very three-dmiensional and it's hard to see among the other crystals in a two-dimensional photo. Now the twin itself is contacted, and not 100% complete, but is certainly one of the few pieces I have had to offer in the auctions for a while. Small cabinet display specimens of Japan-Law twin Quartzes from Siglo XX are simply not seen on the market anymore.
