Description

This is a little specimen that cought my attention from the first moment. The quartz is developed as smoky-quartz with very good quality: excellent luster and clearity. You can call it gemmy. The termination is perfect and some crystals are double-terminated. The specimens backside shows some fine crystallized byssolite. No damage, just a good specimen.
