Cornwall","description":"\u003cp\u003eA beautiful and substantial \u003cstrong\u003ehoney yellow fluorite specimen from Wheal Mary Ann, Menheniot, Cornwall\u003c\/strong\u003e, featuring an intricate arrangement of translucent cubic crystals, delicate cream-coloured secondary mineral growth and remarkable violet-blue fluorescence under ultraviolet light.\u003c\/p\u003e\n\n\u003cp\u003eWeighing an impressive \u003cstrong\u003e590g\u003c\/strong\u003e, this specimen combines pale champagne and golden-yellow fluorite with contrasting peach-cream crystalline deposits, naturally occurring iron staining and complex geometric crystal formations.\u003c\/p\u003e\n\n\u003ch3\u003eSpecimen Description\u003c\/h3\u003e\n\n\u003cp\u003eThis striking Cornish fluorite specimen displays an intricate landscape of \u003cstrong\u003etranslucent honey-yellow and champagne-coloured cubic crystals\u003c\/strong\u003e, partially covered by delicate pale peach and creamy-white secondary mineral growth.\u003c\/p\u003e\n\n\u003cp\u003eThe principal display face features numerous interlocking fluorite crystals, forming a beautiful arrangement of stepped cubic surfaces, angular edges and reflective crystal faces.\u003c\/p\u003e\n\n\u003cp\u003eMany of these crystals retain a glass-like translucency, allowing light to penetrate the mineral and reveal subtle variations in colour, from pale yellow and warm champagne to soft grey-green.\u003c\/p\u003e\n\n\u003cp\u003eOne of the specimen's most distinctive features is the contrasting \u003cstrong\u003ecream to pale peach secondary mineral coating\u003c\/strong\u003e scattered across the central crystalline surface.\u003c\/p\u003e\n\n\u003cp\u003eThese textured deposits form small, irregular clusters and delicate crust-like formations between and over the fluorite crystals, creating an attractive contrast between the smooth geometric surfaces and the softer secondary growth.\u003c\/p\u003e\n\n\u003cp\u003eThe precise identity of this associated mineral has not been independently confirmed.\u003c\/p\u003e\n\n\u003cp\u003eAcross the reverse and sides, larger translucent fluorite sections display broad natural cleavage surfaces and angular crystalline structures.\u003c\/p\u003e\n\n\u003cp\u003eThese areas show a slightly cooler grey-green colouration, contrasting beautifully with the warmer golden-yellow tones visible across the principal display face.\u003c\/p\u003e\n\n\u003cp\u003eRusty-orange and dark brown mineral staining occurs along several crystal boundaries and fractures, adding further geological character.\u003c\/p\u003e\n\n\u003cp\u003eUnder ultraviolet illumination, the specimen displays a particularly attractive \u003cstrong\u003eviolet-blue fluorescent response\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThe UV photograph reveals glowing purple-blue crystalline areas, with the cubic structures remaining clearly visible beneath the fluorescence.\u003c\/p\u003e\n\n\u003cp\u003eThis contrast between its warm natural colouring and vivid ultraviolet appearance makes the specimen especially interesting for collectors who appreciate fluorescent minerals.\u003c\/p\u003e\n\n\u003cp\u003eMeasuring \u003cstrong\u003e71.6mm × 74.4mm and weighing 590g\u003c\/strong\u003e, this substantial specimen offers an impressive combination of crystalline detail, natural colour variation and historic Cornish mineral provenance.\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 extraordinary range of colours, including purple, blue, green, yellow, pink, grey and colourless varieties.\u003c\/p\u003e\n\n\u003cp\u003eIts colouration can be influenced by trace impurities, structural defects and the geological conditions present during mineral formation.\u003c\/p\u003e\n\n\u003cp\u003eHoney-yellow fluorite is especially attractive for its warm golden colouring and varying degrees of translucency.\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 and chemistry, 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 hydrothermal minerals.\u003c\/p\u003e\n\n\u003cp\u003eIts distinctive cubic crystal habit is one of its most recognisable characteristics, although fluorite also possesses perfect octahedral cleavage.\u003c\/p\u003e\n\n\u003cp\u003eThese cleavage planes can produce angular surfaces and complex internal structures when crystals naturally fracture.\u003c\/p\u003e\n\n\u003cp\u003eAnother notable characteristic of fluorite is its potential to exhibit \u003cstrong\u003efluorescence under ultraviolet light\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eFluorescence occurs when certain impurities or structural features within the mineral absorb ultraviolet radiation and re-emit some of that energy as visible light.\u003c\/p\u003e\n\n\u003cp\u003eThe resulting colours vary depending on the mineral's composition and the wavelength of ultraviolet light used.\u003c\/p\u003e\n\n\u003cp\u003eThis specimen displays a visible violet-blue fluorescent response in the supplied UV photograph.\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 surrounding 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 significant 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 contain economically valuable silver.\u003c\/p\u003e\n\n\u003cp\u003eThese mineral deposits developed 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 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\u003eHistorical geological observations indicate that multiple episodes of fluorite mineralisation occurred at Wheal Mary Ann.\u003c\/p\u003e\n\n\u003cp\u003eThis suggests that the mineral veins experienced changing geological conditions and successive periods of mineral deposition.\u003c\/p\u003e\n\n\u003cp\u003eSuch processes can create complex crystalline associations, overlapping mineral growth and variations in crystal development.\u003c\/p\u003e\n\n\u003cp\u003eThe combination of translucent fluorite and contrasting secondary mineral deposits makes this specimen particularly interesting from a geological perspective.\u003c\/p\u003e\n\n\u003cp\u003eFluorite specimens attributed to historic Cornish mining localities are especially appealing to collectors interested in British mineralogy, geological history and Cornwall's mining heritage.\u003c\/p\u003e\n\n\u003cp\u003eThis substantial specimen offers a beautiful example of honey-yellow fluorite attributed to Wheal Mary Ann, combining intricate cubic formations, delicate secondary mineral growth and a striking ultraviolet fluorescent response.\u003c\/p\u003e\n\n\u003ch3\u003eIntention \u0026amp; Associated Chakras\u003c\/h3\u003e\n\n\u003cp\u003eWithin traditional crystal healing practices, yellow fluorite is associated with mental clarity, confidence, creativity and personal empowerment.\u003c\/p\u003e\n\n\u003cp\u003eIts warm golden colouring is traditionally connected with the \u003cstrong\u003eSolar Plexus

crystalline formation, displaying a substantial irregular structure with numerous interlocking cubic fluorite crystals.\u003c\/p\u003e\n\n\u003cp\u003eThe principal display face features intricate stepped crystal formations, delicate geometric surfaces and contrasting pale secondary mineral deposits.\u003c\/p\u003e\n\n\u003cp\u003eThese creamy and peach-coloured deposits create an attractive textured appearance against the translucent honey-yellow fluorite.\u003c\/p\u003e\n\n\u003cp\u003eBroad crystal faces and natural cleavage planes are visible across the reverse, revealing further details of the mineral's internal structure.\u003c\/p\u003e\n\n\u003cp\u003eRusty-orange and brown mineral staining highlights several crystal boundaries, adding depth and geological
