Green Calcite Crystal Natural UK Mineral Specimen
£ 7.50
GENUINE GREEN CALCITE – NATURAL UK MINERAL SPECIMENThis Green Calcite crystal is a genuine natural mineral specimen sourced from
the UK. Carefully selected for its colour and crystal character, this piece displays the soft green tones and classic cleavage structure that define calcite. The photograph provided shows the exact specimen you will receive. Please refer to the images for full sizing and scale details.This crystal includes a Certificate of Authenticity lifetime guarantee generic card confirming its authenticity and mineral classification. MINERAL SPECIES & SCIENTIFIC CLASSIFICATIONMineral Name: CalciteChemical Formula: CaCO₃ (Calcium Carbonate)Mineral Class: CarbonateCrystal System: TrigonalHardness: 3 on the Mohs scaleCleavage: Perfect rhombohedral cleavage in three directionsLustre: Vitreous to pearlyTransparency: Transparent to translucentCalcite is one of the most common and widely distributed minerals in the Earth’s crust. It is the principal component of limestone and marble and plays a significant role in sedimentary rock formation.Green calcite owes its colour to trace elements or microscopic inclusions within the calcium carbonate structure. The green tones may range from pale mint to deeper apple-green hues depending on mineral impurities and geological conditions during formation. GEOLOGICAL FORMATION & UK OCCURRENCECalcite forms in a variety of geological environments. It commonly develops in sedimentary settings through precipitation from calcium-rich waters, as well as in hydrothermal veins where mineral-rich fluids deposit carbonate minerals in fractures and cavities.In the UK, calcite is frequently associated with limestone formations and mineral veins. It may occur alongside minerals such as fluorite, galena, baryte and quartz in hydrothermal systems, particularly within historic mining regions.During crystallisation, calcite develops its distinctive rhombohedral cleavage, meaning it breaks along three planes that are not at right angles. This structural characteristic is one of its defining identification features. COLOUR CHARACTERISTICS & CRYSTAL FEATURESThis specimen showcases the natural beauty and structural properties of green calcite.Notable characteristics may include:
• Soft green to apple-green colouration
• Translucent crystal zones
• Visible cleavage faces
• Smooth natural surfaces or minor growth textures
• Subtle internal inclusionsCalcite is known for its strong birefringence, meaning light passing through transparent pieces can appear doubled. While not always visible in every specimen, this optical property is a hallmark of the mineral.No artificial colouring is implied; the green hue is a natural feature of the crystal. COLLECTIBILITY, DISPLAY & TRADITIONAL ASSOCIATIONSGreen calcite is popular among mineral collectors due to its colour and classic carbonate crystal structure. This specimen is suitable for:
• Mineral and crystal collections
• Educational geological displays
• Decorative shelf or cabinet presentation
• Symbolic or spiritual practicesIn various traditions, green calcite has been traditionally associated with growth and renewal in a spiritual sense. This listing focuses strictly on geological origin and mineralogical characteristics.Its soft green tone makes it an attractive addition to both modern and natural-themed displays. AUTHENTICITY & PRESENTATIONThis Green Calcite specimen has been carefully selected for colour quality and overall visual appeal. The image shown is of the exact specimen you will receive.Included with your purchase is a Certificate of Authenticity lifetime guarantee generic card confirming this is a genuine calcite mineral from the UK.A classic example of calcium carbonate formed through sedimentary or hydrothermal processes, this authentic Green Calcite crystal combines geological interest, natural colour and structural elegance in one distinctive collector’s piece.
