Calcite with Hematite on Matrix | 62.2 grams | Fluorescent Crystal | Lane's Quarry, Westfield MA NWA 250 bivalves have no head andThis is a natural cluster formation of large calcite crystals with hematite inclusions. This piece has some white color to translucent crystals with areas of orange red coloring from hematite inclusions, with sharp tabular crystal formations. There are some nicks and imperfections on a few crystals but would still shine in the proper setup. They don't take away from how interesting this piece is. Would be a nice addition to any new or existing
