The lead-zinc mines of the Madan district in Bulgaria’s Rhodope Mountains produce some of the most beautiful sulphide specimens in the world: brilliant galena cubes, sphalerite, and quartz combinations that fill museum cases everywhere. Working mines, so specimens come out through the miners and the trade rather than casual collecting. Buy through the mineral trade.
