Description

Spectacular specimen of falcondoite and willemseite, these are very rare specimens, and this is the type locality for falcondoite.
Only two places in the world has found falcondoite, this mineral is very rare on the market and the few pieces found are at the micro level.
This mine was closed over 10 years ago, eight years ago a rock that had a miner in his home as a souvenir found in his day job in the mine was found, it took several bottles of rum, so the mining agreed to sell, and this rock were achieved just a couple dozen items.
I think, due the size and quality of the specimens, this is the best Falcondoite you can find in the market today.
