Smokey Quartz Crystal Restowerick Quarry UK Genuine Mineral Specimen with Certificate of Authenticity
£ 24.00
GENUINE SMOKEY QUARTZ – RESTOWERICK QUARRY, UKThis Smokey Quartz crystal from Restowerick Quarry, UK, is a genuine and
carefully selected specimen displaying classic British quartz formation. The photograph provided shows the exact crystal you will receive. Please refer to the images for full sizing details and accurate scale.This crystal includes a Certificate of Authenticity lifetime guarantee generic card confirming its genuine origin and mineral identification. MINERAL & GEOLOGICAL CLASSIFICATION – SMOKEY QUARTZSmokey Quartz is a colour variety of Quartz composed of silicon dioxide with the chemical formula SiO₂. It belongs to the tectosilicate mineral group and crystallises in the trigonal division of the hexagonal crystal system.Mineral Name: Quartz (Smokey Quartz variety)Chemical Formula: SiO₂Mineral Group: TectosilicateCrystal System: TrigonalHardness: 7 on the Mohs scaleLustre: VitreousTransparency: Transparent to translucentThe distinctive brown to deep smoky colouration develops naturally through exposure to natural background radiation acting on trace aluminium within the crystal lattice. This process creates colour centres that give Smokey Quartz its characteristic appearance.Crystals typically form six-sided prismatic shapes with pyramidal terminations. Natural striations may be visible along prism faces, reflecting steady crystal growth within open cavities. GEOLOGICAL SETTING – RESTOWERICK QUARRYRestowerick Quarry is situated within a region influenced by granite intrusions associated with the Cornubian Batholith. These granitic bodies were emplaced during the late Carboniferous to early Permian periods and generated extensive hydrothermal systems.Smokey Quartz forms when silica-rich hydrothermal fluids circulate through fractures and voids in the host rock. As these fluids cool and pressure conditions change, quartz precipitates and grows into open spaces, often forming well-developed crystals.The smoky colour may intensify in areas where crystals remained within the host granite for extended geological periods, exposed to low levels of natural radiation.Associated minerals in similar granite-related environments may include feldspar, mica, tourmaline and occasionally cassiterite or other vein minerals, depending on local geochemistry. CRYSTAL CHARACTERISTICS & NOTABLE TRAITSThis Smokey Quartz specimen may display:
• Well-defined hexagonal prism structure
• Sharp, natural pyramidal termination
• Brown to grey smoky colour zoning
• Transparent to translucent clarityInternal inclusions, growth phantoms or slight colour variations may be visible and are part of the crystal’s natural formation history. These features add individuality and geological interest to each specimen.The vitreous lustre and relatively high hardness make quartz durable and suitable for long-term display. GEOLOGICAL IMPORTANCE & COLLECTIBILITYQuartz is one of the most abundant minerals on Earth, yet locality-specific specimens remain desirable for collectors. Smokey Quartz from documented UK quarries such as Restowerick carries regional geological significance.The natural radiation-induced colouration makes Smokey Quartz a particularly interesting variety within the quartz family. Its formation reflects the interaction between granite emplacement, hydrothermal activity and long-term geological processes.This specimen is suitable for mineral cabinets, educational geological collections or collectors of British locality minerals. Because it is a genuine natural crystal, it displays unique structural and surface characteristics shaped by its formation environment. The photograph shows the exact specimen you will receive. AUTHENTICITY & PRESENTATIONThis Smokey Quartz crystal from Restowerick Quarry has been carefully chosen for clarity, crystal form and locality significance. Included with your purchase is a Certificate of Authenticity lifetime guarantee generic card confirming its genuine UK origin.Combining classic granite-related hydrothermal formation with natural smoky colouration, this specimen offers mineral authenticity, geological interest and strong collector appeal in one carefully selected piece.
