This large piece is a great representative specimen from the famous Rogerley Mine, UK locality. The crystals are transparent, lustrous and gemmy green, covering the majority of the matrix, and many are twinned. There are a couple of unnoticeable contacts, but overall the crystals are in superb condition.

Location: Rogerley Mine, Frosterley County, Durham, England
