 | "This is a whopper floater Galena crystal, showing complex hoppered growth on both the front and the back, decorated with golden chalcopyrite! It was so strange to turn this crystal over expecting the find the usual contact on the back, and instead to see wonderfully complex stepped, hoppered growth patterns! I suspect this crystal came loose in the pocket at at some point, but pretty early on, giving it plenty of time to continue growth to form the new faces. At any rate, the preferred display face is still the side with the pretty chalcopyrite crystals. Galena is a popular mineral for rock hounds. Its characteristic cubes, distinctive cleavage and high density make it easy to identify and a favorite in high school geology labs. The structure of Galena is identical to that of halite, NaCl. The two minerals have the same crystal shapes, symmetry and cleavage. Some Galena may contain up to 1% silver in place of lead. The large volume of Galena that is processed for lead produces enough Silver as a by product to make Galena the leading ore of Silver." Location: 19th September Mine, Madan Rhodope Mtns, Bulgaria
