Description

Superb perfectly floating specimen of elongated gray quartz crystals (wolframite inclusions) covered with a large black wolframite (tungsten) crystal and golden cubic pyrite crystals.

Very nice association in perfect conditions.

Minerals from the San Cristobal mine in Bolivia.

The San Cristobal Mine is an open pit silver, lead, and zinc mine located in the department of Potosi, Bolivia.

Here is a video of these crystals of quartz, wolframite and pyrite from Bolivia:
