Lady Annabella fluorite twins are interpenetrating fluorite crystals—two crystals growing through one another—not a separate mineral variety, from the Lady Annabella Mine at Eastgate Quarry, Weardale, County Durham, England. Fluorite specimens have been collected from the quarry since the early 1960s; UK Mining Ventures began dedicated specimen recovery in July 2020 and named the operation after Annabella Bruce, daughter of Ian and Diana Bruce. Specimens range from green and yellow to purple and multicolored, with notable twins from Helen’s Pocket and the Sherry Twins Pocket. Names such as Eastgate fluorite, Weardale fluorite, Harvest Pocket, and Purple Rain Pocket identify the locality or particular finds rather than separate minerals or interchangeable trade names.

Care and handling

Fluorite is soft, with a hardness of 4, and has perfect cleavage, so these cubes can split or chip if dropped or struck; keep them in a padded case. Strong sunlight, heat, and sudden temperature changes can fade or crack them. Clean with a soft, barely damp cloth and dry at once. Avoid soaking, steam, ultrasonic cleaners, and acids. Some matrix in this region contains galena (lead), so wash your hands after handling. Do not make a gem water or elixir with them.

Individual experiences with Lady Annabella Fluorite Twins vary, and their effects are personal and subjective. Approach them with a mindful and open heart, and enjoy them as a rare and beautiful find.
