The variation in colour seen in this piece is due to differences in iron content and exposure to natural irradiation during formation.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe druzy surface consists of well-developed crystal points (euhedral terminations), giving the piece a more textured and dimensional appearance compared to finer druzy specimens. These crystals formed inward from the cavity walls, creating the sparkling surface.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe outer edge shows banded agate and quartz matrix, with natural mineral inclusions and subtle earthy tones. This banding is a typical feature of geode formations and highlights the natural growth environment of the specimen.\u003c\/p\u003e\n\u003cp\u003eMineral: Quartz\u003cbr\u003eFormula: SiO₂\u003cbr\u003eColour: Pale lilac → deep purple\u003cbr\u003eCause of Colour: Iron + natural irradiation\u003cbr\u003eLustre: Vitreous (glassy)\u003cbr\u003eTransparency: Transparent → translucent\u003cbr\u003eStreak: White\u003cbr\u003eHardness: 7 (Mohs)\u003cbr\u003eFracture: Conchoidal\u003cbr\u003eCleavage: None\u003cbr\u003eDensity: ~2.65\u003cbr\u003eCrystal System: Trigonal\u003cbr\u003eHabit: Hexagonal prisms\u003cbr\u003eFormation: Volcanic cavities (geodes)\u003cbr\u003eCommon Locations: Brazil, Uruguay, Zambia\u003cbr\u003eOptical:\u003cbr\u003eRefractive Index: ~1.54–1.55\u003cbr\u003eWeak pleochroism\u003cbr\u003eExtras:\u003cbr\u003eMay fade or turn yellow when heated\u003cbr\u003eOften shows colour zoning or banding\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eCondition\u003cbr\u003eNatural crystal surface with visible inclusions and matrix\u003cbr\u003eVariation in crystal size, clarity, and colour across the face\u003cbr\u003eNatural banding and mineral staining along the edges\u003cbr\u003ePolished sides with a raw crystal interior\u003cbr\u003eNo visible dyeing or artificial enhancement\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eCare Instructions\u003cbr\u003eHandle with care to avoid chipping the crystal points\u003cbr\u003eClean gently using a soft brush or compressed air\u003cbr\u003eAvoid water exposure where possible, as moisture can settle between crystals\u003cbr\u003eKeep out of prolonged direct sunlight to help preserve colour\u003cbr\u003eStore separately to prevent scratching or damage from harder materials\u003c\/p\u003e","brand":"Crystal Ballerz","offers":[{"title":"Default Title","offer_id":53657893470549,"sku":null,"price":18.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1039\/9295\/1125\/files\/rn-image_picker_lib_temp_02625004-cefb-46d6-a613-c2b1e0e3e1ef.jpg?v=1776439662","url":"https:\/\/crystalballerz.co.uk\/products\/amethyst-druzy-heart-carving","provider":"Crystal Ballerz","version":"1.0","type":"link"}
