Its gentle colouring and historic mining locality make it a lovely addition to a British mineral collection.\u003c\/p\u003e\n\n\u003ch3\u003eSpecimen Description\u003c\/h3\u003e\n\n\u003cp\u003eThis charming specimen displays a delicate combination of \u003cstrong\u003epale mint-green, soft sea-glass green, icy white and translucent champagne\u003c\/strong\u003e, with scattered rusty-orange mineral staining.\u003c\/p\u003e\n\n\u003cp\u003eThe specimen has a naturally irregular, slightly elongated formation, with a broad crystalline centre surrounded by overlapping angular mineral growth.\u003c\/p\u003e\n\n\u003cp\u003eIts most distinctive feature is the pale green fluorite visible across the central and lower sections, where translucent crystal faces reveal subtle internal cloudiness and changes in colour intensity.\u003c\/p\u003e\n\n\u003cp\u003eSeveral broad, angular surfaces intersect across the specimen, producing a naturally geometric appearance.\u003c\/p\u003e\n\n\u003cp\u003eSome crystalline areas possess a glass-like lustre, while others have a softer, frosted texture that catches and diffuses the light.\u003c\/p\u003e\n\n\u003cp\u003eAlong the upper surface, smaller pale and almost colourless crystalline sections create a delicate, layered appearance.\u003c\/p\u003e\n\n\u003cp\u003eThese lighter areas contrast beautifully with the slightly deeper sea-green fluorite beneath them.\u003c\/p\u003e\n\n\u003cp\u003eFine natural surface markings, stepped crystalline boundaries and irregular edges add further detail to the specimen.\u003c\/p\u003e\n\n\u003cp\u003eOne side reveals a particularly attractive arrangement of overlapping crystal faces, with pale green sections transitioning into creamy-white and champagne-coloured mineralisation.\u003c\/p\u003e\n\n\u003cp\u003eSmall patches of golden-orange and rusty-brown staining are visible along several crystal boundaries and outer edges.\u003c\/p\u003e\n\n\u003cp\u003eThese markings are consistent in appearance with iron-bearing mineral staining, although their precise composition has not been independently confirmed.\u003c\/p\u003e\n\n\u003cp\u003eFrom another angle, the specimen displays a more compact arrangement of pale green crystalline faces, with slightly clearer areas visible beneath the frosted outer growth.\u003c\/p\u003e\n\n\u003cp\u003eThe natural contrast between the translucent central fluorite and the more textured surrounding crystal growth gives this piece considerable visual interest.\u003c\/p\u003e\n\n\u003cp\u003eIts irregular edges, internal fractures, intersecting crystal boundaries and subtle mineral staining are characteristic features of an unpolished mineral specimen.\u003c\/p\u003e\n\n\u003cp\u003eMeasuring \u003cstrong\u003e34.6mm × 56.3mm and weighing 105g\u003c\/strong\u003e, this is a lovely example of pale sea-green fluorite attributed to the historic Wheal Mary Ann locality.\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 admired for its remarkable range of natural colours, including purple, blue, green, yellow, pink, brown and colourless varieties.\u003c\/p\u003e\n\n\u003cp\u003eThese colours can develop through structural defects, trace impurities and geological conditions during crystal formation.\u003c\/p\u003e\n\n\u003cp\u003eGreen fluorite may range from the palest mint and sea-glass shades to deeper emerald, olive and forest-green tones.\u003c\/p\u003e\n\n\u003cp\u003eVariations in colour and transparency can occur within a single specimen, creating subtle differences in appearance as light passes through individual crystalline sections.\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 undergo changes in temperature, pressure or chemical composition, dissolved minerals may crystallise within the available spaces.\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 means the mineral can separate along particular crystallographic planes, producing distinctive angular surfaces.\u003c\/p\u003e\n\n\u003cp\u003eAlthough fluorite commonly forms cubic crystals, natural cleavage and breakage can create triangular, stepped and irregular geometric formations.\u003c\/p\u003e\n\n\u003cp\u003eFluorite typically possesses a vitreous, or glass-like, lustre, although natural weathering, fine surface textures and mineral coatings can produce a softer, frosted appearance.\u003c\/p\u003e\n\n\u003cp\u003eSome fluorite specimens exhibit fluorescence under ultraviolet light, although this property varies between individual specimens and localities.\u003c\/p\u003e\n\n\u003cp\u003eUltraviolet fluorescence has not been confirmed for this specimen.\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 deposits developed through hydrothermal geological processes, with heated mineral-rich fluids circulating through fractures in the surrounding rocks.\u003c\/p\u003e\n\n\u003cp\u003eOver time, these 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 particularly interesting because historical geological investigations 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 identifies 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 geological memoir describes quartz as a significant vein-filling mineral, with chalcedonic material occurring along portions 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 complex mineral associations, overlapping crystalline formations and variations in crystal development.\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, combining delicate sea-green colouration, translucent angular crystal faces and naturally occurring mineral 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, personal growth and maintaining a peaceful perspective.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003ePale green fluorite\u003c\/strong\u003e is commonly connected with calmness, harmony and clear thinking.\u003c\/p\u003e\n\n\u003cp\u003eIts gentle green colouration is traditionally associated with the Heart Chakra, symbolically representing emotional balance, compassion and peaceful connection.\u003c\/p\u003e\n\n\u003cp\u003eFluorite as a mineral is also frequently associated with organisation, concentration and supporting a calm, balanced mindset.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePeace \u0026amp; Calm:\u003c\/strong\u003e Traditionally associated with

overlapping angular surfaces, subtle internal fractures and contrasting translucent and frosted areas.\u003c\/p\u003e\n\n\u003cp\u003eIts slightly elongated, irregular formation creates an attractive silhouette, while the broad central crystalline faces give the specimen a distinctive geometric appearance.\u003c\/p\u003e\n\n\u003cp\u003eThe pale sea-green colouration creates a soft, almost aquatic appearance, contrasting with the icy-white and champagne-coloured crystalline sections.\u003c\/p\u003e\n\n\u003cp\u003eSeveral crystal faces display fine natural surface markings, while smaller intergrown sections create additional texture along the specimen's outer edges.\u003c\/p\u003e\n\n\u003cp\u003eScattered golden-orange mineral staining highlights selected crystal boundaries and fractures, adding warmth to the otherwise cool colour palette.\u003c\/p\u003e\n\n\u003cp\u003eWithin traditional crystal symbolism, green fluorite is associated with emotional harmony, mental clarity and personal growth.\u003c\/p\u003e\n\n\u003cp\u003eBeyond these symbolic associations, this specimen's principal appeal lies in its delicate natural colouration, intricate crystalline structure and
