Description

A wonderful combination, full of contrast. The matrix with dark green spheres of malachite is very tridimensional, it nearly forms a geode. In the center you can see a group of free-standing baryte crystals. These crystals show good transparecny (more clear as seen on images), sharp stepped termination and good luster. The assemble is really very aesthetic and this combination is rare, this material is from old discoveries and hard to obtain. No significant damages to report.
