Calcite on Quartz

An exceptional calcite on quartz from a one-off pocket at the Borieva Mine, in the Madan ore field, within the Rhodope Mtns., of Bulgaria! This pocket was discovered in late July of 2017, and I acquired the bulk of the find. This specimen features several yellow to amber calcite crystals on a bed of quartz crystals, colored green by inclusions of chlorite. The contrast of color is outstanding! The calcite crystals are interesting, in that, they are scalenohedral crystals, comprised of hundreds of flattened and stacked rhombohedrons. The arrangement of the the calcite on the quartz crystals is very aesthetic to my eye. This is one of my favorites from the pocket. Some broken quartz crystals on the edge and one in the middle of the specimen, but it really doesn’t detract in my mind, from the overall appeal of the specimen.
