Calcite on Barite

Honey calcites up to 3.5cm scale a snow white barite matrix with some tiny black (sphalerite?) crystals adding contrast.  The GP has been worked recently and ongoing and has produced some exceptional sphalerites as well as quartz specimens. Some minor tipping on a few calcites. Ex Kenny Gay collection.
