Description
British Fluorite Mineral Specimen
This genuine British fluorite specimen is identified with the Boltsburn Mine, Rookhope, County Durham, England. It is a collectible mineral from the United Kingdom, suitable for mineral collectors, British geology enthusiasts, display cabinets, educational collections and distinctive natural-history gifts. The locality name makes this specimen especially relevant to collectors who focus on minerals from County Durham and the historic mining districts of northern England.
Mineral Information
Fluorite is the mineral form of calcium fluoride, with the chemical formula CaF₂. It belongs to the halide mineral group and crystallises in the cubic crystal system. Fluorite is widely recognised by mineral collectors for its varied colour range, which can include purple, green, blue, yellow, colourless and combinations of these shades. Colour can vary between individual specimens, and the appearance of a natural specimen is part of its geological character.
Fluorite has a Mohs hardness of 4 and is known for its distinctive perfect octahedral cleavage. These characteristics are important in mineral identification and explain why fluorite is valued both as a study specimen and as a display mineral. Some fluorite specimens can show fluorescence under ultraviolet light, although this property varies and should not be assumed for every individual specimen.
Boltsburn Mine and Rookhope
Boltsburn Mine is associated with Rookhope in County Durham, an area recognised for its long history of mineral extraction and geological interest. Northern England has produced many noteworthy mineral specimens, and locality-labelled material is collected for the connection it provides between the mineral and its natural geological setting. A named mine and regional locality add useful context to a specimen display, collection label or geology study.
Collecting and Display
This British fluorite is well suited to a dedicated mineral cabinet, geological teaching collection, office display, shelf arrangement or gift for someone interested in rocks and minerals. It can be displayed alongside other English or United Kingdom specimens to create a regional collection, or used as an accessible example when discussing mineral classification, crystal systems, hardness and cleavage. Fluorite is also a popular choice for collectors because its scientific characteristics and broad natural colour range make it easy to compare with other mineral species.
