The main cubic crystal measures 3.7 cm on edge and is associated with siderite. The specimen displays better in person or video where the subtle color nuances are more apparent. A fine example showcasing an atypical coloration from England's classic fluorite-producing districts Ex coll. Bouzat Ex mineralauctions.com
