PYRITE, SPHALERITE, QUARTZ

On a group of sharp cubic pyrite crystals of good size and better brightness, several aggregates of octahedral sphalerite crystals are disposed very aesthetically; with defined edges and complex faces with inverse hopper growths. Intense black color and brightness. We can observe fissures in the pyrite crystals that have been recrystallized by quartz crystals, very interesting. Pure aesthetics. The main crystal is: 4,8 x 4,4 x 3,9 cm.
