MM Quartz Coral Formation Natural Mineral Specimen # B 6472Features The specimen is made up of milky Quartz that has pseudomorphed following scalenohedral Calcite crystals. The item is crystallized nearly all the way around, with no matrix and only a few small points of attachment, and is thus on the verge of becoming a complete "floater." This type of specimen is quite rare on the market, and this one is extremely striking, three dimensional, and eye catching. Primary Mineral(s): MM Quartz Secondary
