This variation is caused by a combination of natural irradiation (responsible for smoky quartz) and iron impurities within the crystal structure.\u003c\/p\u003e\n\u003cp\u003eThe specimen features several well-defined terminations emerging from a shared base, forming a clustered growth habit. Each point displays classic hexagonal geometry with sharp edges and natural faces, some of which show horizontal growth lines that mark pauses in crystal formation.\u003c\/p\u003e\n\u003cp\u003e🔍 Key Features\u003c\/p\u003e\n\u003cp\u003eMaterial: Natural Quartz (Smoky Citrine)\u003c\/p\u003e\n\u003cp\u003eFormula: SiO₂\u003c\/p\u003e\n\u003cp\u003eColour: Golden yellow → smoky brown\u003c\/p\u003e\n\u003cp\u003eCause of Colour: Iron impurities + natural irradiation\u003c\/p\u003e\n\u003cp\u003eTransparency: Transparent to translucent\u003c\/p\u003e\n\u003cp\u003eLustre: Vitreous (glassy)\u003c\/p\u003e\n\u003cp\u003eCrystal System: Trigonal\u003c\/p\u003e\n\u003cp\u003eFormation: Natural multi-point cluster\u003c\/p\u003e\n\u003cp\u003e📏 Dimensions\u003c\/p\u003e\n\u003cp\u003eSize: 8.7 cm x 6.7 cm\u003c\/p\u003e\n\u003cp\u003eWeight: 155 grams\u003c\/p\u003e\n\u003cp\u003e🧪 Geological \u0026amp; Scientific Notes\u003c\/p\u003e\n\u003cp\u003eQuartz forms from silica-rich fluids within cavities in rock, often under hydrothermal conditions. Over time, crystals grow layer by layer, creating the hexagonal forms seen in this specimen.\u003c\/p\u003e\n\u003cp\u003eThe smoky tones are produced when natural radiation interacts with aluminium impurities in the quartz lattice, forming colour centres. The yellow to golden tones are linked to iron content within the crystal.\u003c\/p\u003e\n\u003cp\u003eThis piece shows both processes, resulting in a natural “smoky citrine” appearance rather than a single uniform colour. The visible zoning and phantoms reflect changes in growth conditions during formation.\u003c\/p\u003e\n\u003cp\u003eSurface textures, minor contact points, and natural etching are typical of unpolished quartz clusters and add to the authenticity of the specimen.\u003c\/p\u003e\n\u003cp\u003e🧼 Care Information\u003c\/p\u003e\n\u003cp\u003eClean gently with lukewarm water\u003c\/p\u003e\n\u003cp\u003eAvoid harsh chemicals\u003c\/p\u003e\n\u003cp\u003eStore carefully to protect crystal points\u003c\/p\u003e\n\u003cp\u003eHandle with care – natural terminations can be delicate\u003c\/p\u003e","brand":"Crystal Ballerz","offers":[{"title":"Default Title","offer_id":53756072296789,"sku":null,"price":38.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1039\/9295\/1125\/files\/rn-image_picker_lib_temp_5b788840-f935-41d7-b320-403b24961d60.jpg?v=1776966900","url":"https:\/\/crystalballerz.co.uk\/products\/natural-smoky-citrine-cluster","provider":"Crystal Ballerz","version":"1.0","type":"link"}
