Size Range: 
Miniature (4.5-7 cm)
Size: 
4.5 × 4 × 3 cm
Description

Excellent crystal of spinel twinned galena on this fine miniature.

Crystals are razor sharp, lustrous and well exposed on the sphalerite matrix.

One of the twins is contacted. The specimen can be cleaned to remove the clay and leave only sphalerite with calcite on the matrix,but I leave this to the collector's judgment.

The quality is very high!
