Its combination of muted grey-green fluorite, honey-coloured crystal surfaces and naturally weathered textures makes it an attractive addition to a British mineral collection.\u003c\/p\u003e\n\n\u003ch3\u003eSpecimen Description\u003c\/h3\u003e\n\n\u003cp\u003eThis fascinating fluorite specimen displays a beautiful combination of \u003cstrong\u003esmoky grey-green, pale champagne, honey yellow, creamy white and warm golden-orange\u003c\/strong\u003e tones.\u003c\/p\u003e\n\n\u003cp\u003eIts irregular, roughly wedge-shaped formation reveals several overlapping crystalline sections, each displaying different levels of transparency and surface texture.\u003c\/p\u003e\n\n\u003cp\u003eOne of its most striking features is the broad area of translucent grey-green fluorite extending across the central portion of the specimen.\u003c\/p\u003e\n\n\u003cp\u003eThese smoky, glass-like surfaces contrast beautifully with the softer honey-yellow and creamy-white crystalline material surrounding them.\u003c\/p\u003e\n\n\u003cp\u003eThe grey-green sections display angular boundaries, internal fractures and overlapping cleavage surfaces that create depth within the mineral.\u003c\/p\u003e\n\n\u003cp\u003eViewed from different angles, light passes through the more translucent areas, revealing subtle variations in colour and internal structure.\u003c\/p\u003e\n\n\u003cp\u003eAlong the upper edge, pale cream and champagne-coloured crystal growth forms a naturally uneven surface, with small areas of golden-yellow staining.\u003c\/p\u003e\n\n\u003cp\u003eOne side of the specimen displays particularly attractive honey-yellow and amber-coloured mineralisation, creating a warm contrast against the cooler grey-green fluorite.\u003c\/p\u003e\n\n\u003cp\u003eThe reverse reveals additional crystalline detail, including larger translucent grey sections, pale yellow mineral growth and angular internal structures.\u003c\/p\u003e\n\n\u003cp\u003eNatural fractures and cleavage planes create reflective surfaces throughout the specimen, giving certain areas a delicate glass-like lustre.\u003c\/p\u003e\n\n\u003cp\u003eSmall patches of rusty-orange and brown staining are scattered across the crystal surfaces, visually consistent with the presence of iron-bearing mineral material.\u003c\/p\u003e\n\n\u003cp\u003eThese natural markings contribute to the specimen's distinctive appearance and highlight its geological character.\u003c\/p\u003e\n\n\u003cp\u003eSome areas appear smooth and translucent, while others exhibit a more granular, frosted or naturally weathered texture.\u003c\/p\u003e\n\n\u003cp\u003eThe combination of contrasting colours, complex crystalline formations and naturally irregular surfaces makes this an especially interesting specimen to examine from multiple angles.\u003c\/p\u003e\n\n\u003cp\u003eMeasuring \u003cstrong\u003e50.3mm × 45.8mm and weighing 110g\u003c\/strong\u003e, this individual specimen is attributed to the historic Wheal Mary Ann mineral locality in Cornwall.\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 particularly admired for its remarkable variety of natural colours, including purple, green, blue, yellow, pink and colourless varieties.\u003c\/p\u003e\n\n\u003cp\u003eIts colouration can be influenced by trace impurities, structural defects and geological conditions during mineral formation.\u003c\/p\u003e\n\n\u003cp\u003eGrey-green fluorite may display muted sage, smoky green or translucent grey tones, while yellow varieties can range from pale champagne to rich golden amber.\u003c\/p\u003e\n\n\u003cp\u003eColour variations within individual specimens can reflect differences in crystal growth, internal structure and the conditions under which mineralisation occurred.\u003c\/p\u003e\n\n\u003cp\u003eFluorite commonly forms within hydrothermal mineral veins, where heated, mineral-rich fluids circulate through fractures and cavities in surrounding rocks.\u003c\/p\u003e\n\n\u003cp\u003eAs these fluids cool or experience changes in pressure and chemical composition, dissolved minerals may crystallise.\u003c\/p\u003e\n\n\u003cp\u003eFluorite frequently occurs alongside quartz, calcite, baryte, galena, siderite and other minerals associated with hydrothermal 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 particular crystallographic planes, producing distinctive angular surfaces.\u003c\/p\u003e\n\n\u003cp\u003eIts vitreous lustre, variable transparency and intricate crystal formations make fluorite especially appealing to mineral collectors.\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 region 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\u003eThese mineral deposits formed through hydrothermal geological processes, as heated mineral-rich fluids circulated through fractures within the surrounding rocks.\u003c\/p\u003e\n\n\u003cp\u003eOver time, these fluids deposited a varied assemblage of minerals, including quartz, fluorite, galena, siderite and other associated species.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003eBritish Geological Survey's geological memoir covering Plymouth and South-East Cornwall\u003c\/strong\u003e documents 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 extracted.\u003c\/p\u003e\n\n\u003cp\u003eThe memoir describes quartz as a significant vein-filling mineral, with crystalline quartz, galena and siderite 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 mineral deposition under changing geological conditions.\u003c\/p\u003e\n\n\u003cp\u003eSuch processes can produce complex mineral associations, overlapping crystal formations and variations in mineral growth.\u003c\/p\u003e\n\n\u003cp\u003eFluorite from historic Cornish mining 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, combining smoky grey-green translucency, warm honey-yellow colouration and naturally contrasting mineral textures.\u003c\/p\u003e\n\n\u003ch3\u003eIntention

sections.\u003c\/p\u003e\n\n\u003cp\u003eThe translucent grey-green areas create a striking contrast against the warmer honey-yellow and creamy-white mineral growth.\u003c\/p\u003e\n\n\u003cp\u003eAngular crystal boundaries and natural cleavage planes reveal the mineral's distinctive internal structure.\u003c\/p\u003e\n\n\u003cp\u003eSmall areas of rusty-orange staining add further visual interest, emphasising the specimen's natural geological character.\u003c\/p\u003e\n\n\u003cp\u003eSome crystal surfaces exhibit a smooth, glass-like lustre, while others display a more textured or naturally frosted appearance.\u003c\/p\u003e\n\n\u003cp\u003eWithin traditional crystal symbolism, green fluorite is associated with emotional harmony and renewal, while yellow fluorite represents confidence and personal empowerment.\u003c\/p\u003e\n\n\u003cp\u003eBeyond these symbolic associations, the specimen's principal appeal lies in its
