3.7" Quartz With Pyrite Cubes & Calcite - Bulgaria

This is an aesthetic plate of clear quartz crystals with pyrite cubes and balls of calcite from the Madan ore fields of Bulgaria. The entire piece is 3.7" wide and the longest crystals measure about 0.6"

The Madan Ore Fields have been known since the middle ages, being a big source of lead and zinc in the Middle Ages, and mined extensively in the past 50 years. There are more than 40 underground mines, and in addition to the ore, sometimes spectacular pockets of sphalerite, galena, chalcopyrite and pyrite crystals are discovered.
