Its gentle greenish-grey tones contrast with warmer honey and cream-coloured sections, creating an interesting example of fluorite from Cornwall's historic mining landscape.\u003c\/p\u003e\n\n\u003ch3\u003eSpecimen Description\u003c\/h3\u003e\n\n\u003cp\u003eThis distinctive specimen features a broad, irregular crystalline formation with a softly textured surface and numerous overlapping fluorite crystals.\u003c\/p\u003e\n\n\u003cp\u003eThe principal face displays a mixture of \u003cstrong\u003epale sage-green, greenish-grey, translucent champagne and creamy-white tones\u003c\/strong\u003e, creating a subtle, naturally varied appearance.\u003c\/p\u003e\n\n\u003cp\u003eUnlike specimens dominated by large, clearly defined cubic crystals, this piece displays a more complex arrangement of smaller interlocking formations, fractured crystalline faces and areas of natural surface alteration.\u003c\/p\u003e\n\n\u003cp\u003eSeveral sections reveal translucent fluorite beneath the lighter mineral coatings, allowing subtle variations in colour and internal structure to become visible under changing lighting conditions.\u003c\/p\u003e\n\n\u003cp\u003eThe upper portion features a gently raised, uneven formation with pale greenish-grey crystalline sections and small patches of rusty-orange staining.\u003c\/p\u003e\n\n\u003cp\u003eAcross the central face, numerous angular crystal fragments and naturally fractured surfaces create a layered appearance, with individual sections catching and reflecting light differently.\u003c\/p\u003e\n\n\u003cp\u003eSome areas display a soft glass-like lustre, while others have a more frosted or matte finish due to natural surface textures and mineral coatings.\u003c\/p\u003e\n\n\u003cp\u003eThe specimen also contains scattered \u003cstrong\u003egolden-brown and rusty-orange staining\u003c\/strong\u003e, particularly visible around crystal boundaries, natural fractures and the upper edges.\u003c\/p\u003e\n\n\u003cp\u003eThese warm-toned areas contrast with the cooler greenish-grey fluorite and add further geological character.\u003c\/p\u003e\n\n\u003cp\u003eViewed from the side, the specimen reveals a more elongated, wedge-like profile, with pale translucent crystal sections interspersed with creamy deposits and more concentrated orange-brown staining.\u003c\/p\u003e\n\n\u003cp\u003eThe reverse presents a lighter appearance, dominated by pale cream, soft greenish-grey and translucent mineral formations.\u003c\/p\u003e\n\n\u003cp\u003eNumerous small crystalline surfaces are visible across this face, producing a delicate, uneven texture with subtle variations in transparency.\u003c\/p\u003e\n\n\u003cp\u003eAnother viewing angle reveals more pronounced angular crystal boundaries, with overlapping translucent sections forming a complex natural structure.\u003c\/p\u003e\n\n\u003cp\u003eUnder closer examination, the specimen displays individual crystal faces, internal fractures, small cavities and irregular mineral coatings.\u003c\/p\u003e\n\n\u003cp\u003eSeveral pale greenish-grey crystals show characteristic geometric surfaces and stepped-looking edges, while neighbouring areas are covered by smaller crystalline growths.\u003c\/p\u003e\n\n\u003cp\u003eFine rusty-orange deposits are scattered across the surface, with some staining appearing concentrated along fractures and between individual crystals.\u003c\/p\u003e\n\n\u003cp\u003eMeasuring \u003cstrong\u003e68.8mm × 61.3mm and weighing 185g\u003c\/strong\u003e, this specimen offers an attractive combination of soft colouration, natural crystalline detail and historical locality interest.\u003c\/p\u003e\n\n\u003cp\u003eIts gentle greenish tones and varied textures make it particularly appealing for collectors of British minerals and natural fluorite specimens.\u003c\/p\u003e\n\n\u003ch3\u003eAbout Fluorite\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eFluorite (CaF₂)\u003c\/strong\u003e is a naturally occurring calcium fluoride mineral belonging to the halide mineral group.\u003c\/p\u003e\n\n\u003cp\u003eIt crystallises in the cubic, or isometric, crystal system and has a Mohs hardness of 4.\u003c\/p\u003e\n\n\u003cp\u003eFluorite is recognised for its remarkable range of colours, including green, blue, purple, yellow, pink, brown and colourless varieties.\u003c\/p\u003e\n\n\u003cp\u003eThese colour variations may develop through trace impurities, structural defects and geological processes occurring during mineral formation.\u003c\/p\u003e\n\n\u003cp\u003eGreen fluorite can range from pale mint and delicate sage-green to deeper emerald and olive-green tones.\u003c\/p\u003e\n\n\u003cp\u003eSome specimens display subtle grey or champagne undertones, particularly where translucent crystal sections overlap or where natural mineral coatings are present.\u003c\/p\u003e\n\n\u003cp\u003eFluorite commonly forms in hydrothermal mineral veins, where heated mineral-rich fluids circulate through fractures and cavities within surrounding rocks.\u003c\/p\u003e\n\n\u003cp\u003eAs the fluids cool or their chemical conditions change, dissolved minerals may crystallise along the walls of these openings.\u003c\/p\u003e\n\n\u003cp\u003eFluorite frequently occurs alongside quartz, calcite, baryte, galena, siderite and other minerals associated with hydrothermal ore deposits.\u003c\/p\u003e\n\n\u003cp\u003eOne of fluorite's defining physical characteristics is its \u003cstrong\u003eperfect octahedral cleavage\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThis allows the mineral to separate along specific crystallographic planes, producing distinctive angular surfaces and naturally fractured formations.\u003c\/p\u003e\n\n\u003cp\u003eAlthough fluorite commonly develops cubic crystals, its cleavage surfaces can create triangular and other geometric shapes when crystals are fractured.\u003c\/p\u003e\n\n\u003cp\u003eFluorite typically has a vitreous, or glass-like, lustre, although natural weathering, mineral coatings and surface alteration can produce a softer, frosted appearance.\u003c\/p\u003e\n\n\u003cp\u003eSome fluorite specimens exhibit fluorescence under ultraviolet light, although this varies considerably between individual specimens and mineral localities.\u003c\/p\u003e\n\n\u003cp\u003eUltraviolet fluorescence has not been confirmed for this particular piece.\u003c\/p\u003e\n\n\u003ch3\u003eWheal Mary Ann \u0026amp; Cornish Mining Heritage\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eWheal Mary Ann\u003c\/strong\u003e is a historic mineral locality situated near Menheniot in south-east Cornwall, England.\u003c\/p\u003e\n\n\u003cp\u003eThe Menheniot district forms part of Cornwall's extensive mining landscape and is particularly associated with historic lead and silver mining.\u003c\/p\u003e\n\n\u003cp\u003eAlthough Cornwall is internationally recognised for its tin and copper deposits, the south-eastern part of the county also contains important lead-bearing mineral veins.\u003c\/p\u003e\n\n\u003cp\u003eDuring the nineteenth century, mining operations around Menheniot extracted lead ores, particularly galena, which could also contain economically valuable silver.\u003c\/p\u003e\n\n\u003cp\u003eThe mineral veins of the district formed through hydrothermal geological processes, with mineral-rich fluids circulating through fractures in the surrounding rocks.\u003c\/p\u003e\n\n\u003cp\u003eThese fluids deposited a varied assemblage of minerals, including quartz, fluorite, galena, siderite, calcite and other associated species.\u003c\/p\u003e\n\n\u003cp\u003eWheal Mary Ann is of particular geological interest because historical geological studies document complex relationships between successive generations of mineral deposition.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eBritish Geological Survey's geological memoir covering Plymouth and South-East Cornwall\u003c\/strong\u003e records fluorite as an important gangue mineral at Wheal Mary Ann.\u003c\/p\u003e\n\n\u003cp\u003eGangue minerals occur alongside economically valuable ores but are not necessarily the principal materials being mined.\u003c\/p\u003e\n\n\u003cp\u003eThe memoir describes quartz as a significant vein-filling mineral, with chalcedonic material occurring along parts of the vein walls.\u003c\/p\u003e\n\n\u003cp\u003eCrystalline quartz, galena and siderite are also documented within the mineral sequence.\u003c\/p\u003e\n\n\u003cp\u003eHistorical geological observations indicate that at least two generations of fluorite mineralisation occurred at Wheal Mary Ann.\u003c\/p\u003e\n\n\u003cp\u003eThis suggests that the mineral veins experienced multiple episodes of deposition under changing geological conditions.\u003c\/p\u003e\n\n\u003cp\u003eSuch processes can produce overlapping crystalline formations, variations in colour and complex mineral associations.\u003c\/p\u003e\n\n\u003cp\u003eFluorite from historic Cornish localities is particularly appealing to collectors interested in British mineralogy, geological history and the country's mining heritage.\u003c\/p\u003e\n\n\u003cp\u003eThis specimen offers an attractive example of fluorite attributed to Wheal Mary Ann, with its soft greenish-grey colouring, translucent crystalline sections and natural iron-coloured staining.\u003c\/p\u003e\n\n\u003ch3\u003eIntention \u0026amp; Associated Chakras\u003c\/h3\u003e\n\n\u003cp\u003eWithin traditional crystal healing practices, green fluorite is associated with emotional balance, mental clarity, calm and personal understanding.\u003c\/p\u003e\n\n\u003cp\u003eGreen fluorite is commonly connected with the \u003cstrong\u003eHeart Chakra\u003c\/strong\u003e, symbolically representing emotional harmony, compassion and balance.\u003c\/p\u003e\n\n\u003cp\u003eFluorite is also traditionally associated with the Third Eye Chakra, which represents intuition, awareness and clear thinking.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCalm:\u003c\/strong\u003e Traditionally associated with peaceful

Symbolism\u003c\/h3\u003e\n\n\u003cp\u003eThis specimen retains its natural crystalline structure, irregular edges, exposed cleavage surfaces and areas of pale mineral coating.\u003c\/p\u003e\n\n\u003cp\u003eIts softly translucent greenish-grey crystals create a gentle appearance, with overlapping formations producing subtle variations in colour and depth.\u003c\/p\u003e\n\n\u003cp\u003eThe numerous small crystal faces contrast with larger, more opaque sections, creating an interesting mixture of textures across the specimen.\u003c\/p\u003e\n\n\u003cp\u003eRusty-orange staining adds warmth to the otherwise cool-toned mineral, particularly around natural fractures and crystalline boundaries.\u003c\/p\u003e\n\n\u003cp\u003eWithin traditional crystal symbolism, green fluorite is associated with emotional harmony, calm reflection and mental clarity.\u003c\/p\u003e\n\n\u003cp\u003eThe softer green tones are often connected with the Heart Chakra, while fluorite's broader associations include concentration and intuitive understanding.\u003c\/p\u003e\n\n\u003cp\u003eBeyond these symbolic interpretations, the specimen's appeal lies in its natural formation, subtle colour variations and connection to Cornwall's historic mineral-producing landscape.\u003c\/p\u003e\n\n\u003ch3\u003eSpecimen Details\u003c\/h3\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral:\u003c\/strong\u003e
