£ 64.80
CALCITE CRYSTAL SPECIMEN – TAFFS WELL QUARRY, CARDIFF, WALES, UKThis Calcite crystal specimen from Taffs Well Quarry, Cardiff, Wales, UK is a
genuine natural mineral specimen, carefully selected for its crystal structure, natural lustre, and classic British locality appeal. Featuring naturally formed calcite crystal growth on matrix, this specimen is an excellent addition to mineral collections, Welsh geological displays, and collector cabinets specialising in classic UK mineral localities.The exact specimen shown in the photographs is the one you will receive, ensuring complete individuality in crystal habit, colouration, matrix texture, and natural mineral formation. Full sizing information is available within the listing photographs for accurate scale reference.This crystal includes a Certificate of Authenticity lifetime guarantee generic card confirming the authenticity of the specimen. WHAT IS CALCITE? – MINERAL SPECIES AND COMPOSITIONCalcite is a calcium carbonate mineral with the chemical formula CaCO₃ and is one of the most widespread and important minerals found within the Earth’s crust. It crystallises within the trigonal crystal system and occurs in a remarkable variety of crystal habits, colours, and geological environments.As the principal mineral component of limestone and marble, calcite plays a major role in sedimentary geology and carbonate rock formation. It is also commonly found in hydrothermal veins, cave systems, metamorphic rocks, and mineralised fractures where crystal growth occurs through the precipitation of calcium-rich fluids.Calcite is especially prized among collectors for its diverse crystal forms, vitreous to pearly lustre, and optical characteristics. Depending on locality and formation conditions, calcite can occur as transparent, translucent, rhombohedral, scalenohedral, dogtooth, bladed, or massive crystal formations. TAFFS WELL QUARRY LOCALITY – CARDIFF, WALESTaffs Well Quarry near Cardiff, Wales is a recognised British geological locality known for producing attractive mineral specimens associated with carbonate rock formations and hydrothermal mineralisation. Welsh mineral localities are highly collectable among enthusiasts of classic UK minerals due to their geological history and limited availability.Calcite specimens from Welsh quarries often occur within limestone-hosted environments where mineral-rich fluids circulated through fractures and cavities, allowing crystals to develop over long geological timescales. The resulting specimens preserve the natural mineralogy and geological character associated with these historic British localities.This specimen represents an authentic piece of Welsh geological history and is especially appealing for collectors of UK mineral specimens and regional geology. CRYSTAL HABIT AND NATURAL FEATURESThis calcite specimen displays natural crystalline growth typical of authentic calcite mineralisation. Depending on the individual piece, the crystals may exhibit rhombohedral faces, scalenohedral formations often referred to as “dogtooth calcite,” or layered crystalline textures naturally developed within cavities of the host rock matrix.The specimen may feature transparent to translucent crystal sections, vitreous lustre, stepped crystal growth, or naturally reflective crystal faces that catch the light beautifully from different angles. Calcite often forms complex intergrown crystal structures, producing attractive natural geometry and dimensional depth.Natural inclusions, internal fractures, matrix attachment points, iron staining, or slight mineral zoning are common features of authentic calcite specimens and contribute to the uniqueness and geological authenticity of the piece. GEOLOGICAL FORMATION AND CARBONATE MINERALISATIONCalcite forms through a variety of geological processes, including sedimentary deposition, hydrothermal activity, and metamorphic recrystallisation. In quarry environments such as Taffs Well, calcite crystals commonly develop when calcium-rich groundwater or hydrothermal fluids precipitate minerals within open fractures and cavities in limestone formations.Over extended geological periods, these fluids gradually deposit layers of calcite crystals, sometimes producing well-formed crystal groups and sparkling cavity linings. Variations in temperature, pressure, and trace mineral chemistry during growth influence crystal habit, clarity, and colouration.Calcite’s widespread occurrence and highly variable crystal habits make it one of the most studied and collected minerals in mineralogy and geology. BRITISH MINERAL COLLECTOR SPECIMENThis Taffs Well Quarry calcite specimen combines attractive crystal growth with an important British locality, making it particularly desirable for collectors of UK minerals and geological specimens.Ideal for:
• British mineral collections
• Welsh geology collections
• Calcite crystal displays
• Geological specimen cabinets
• Collector showcase displays
• Natural history collections
• Educational geology collections
• Decorative mineral arrangementsIts reflective crystal surfaces and natural matrix presentation make it especially attractive under directional lighting where the crystal faces and lustre become more prominent. GENUINE CALCITE SPECIMEN GUARANTEEThis Calcite specimen from Taffs Well Quarry, Cardiff, Wales, UK is a genuine natural mineral specimen. The listing photographs show the exact specimen you will receive, carefully selected for quality, crystal formation, and presentation.Includes a Certificate of Authenticity lifetime guarantee generic card.
