{"product_id":"amethyst-druzy-cupcake","title":"Amethyst druzy cupcake","description":"\u003cp\u003eThis is a carved amethyst druzy specimen shaped into a cupcake-like form, featuring a natural mix of soft purple tones. The surface displays fine to medium crystal points in pale lavender hues, with subtle variation into near-clear quartz. These crystals sit atop a visible agate\/quartz matrix, with earthy banding running around the base.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eKey Features\u003cbr\u003eMaterial: Natural amethyst (quartz variety)\u003cbr\u003eFormation: Druzy crystal growth over agate\/quartz matrix\u003cbr\u003eColor: Pale to medium lavender with areas of near-clear quartz\u003cbr\u003eCrystal Habit: Fine to medium druzy points with a sparkling, glassy lustre\u003cbr\u003eFinish: Polished outer edges with raw druzy crystal surface\u003cbr\u003eShape: Cupcake-style carving (lapidary-shaped)\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eDimensions\u003cbr\u003eApprox.

The softer, pastel colouring in this piece reflects lower concentrations of iron and varying exposure to natural irradiation during its formation.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe druzy surface is composed of tightly packed crystal points that formed inward from the cavity walls, creating a sparkling, textured finish. Compared to larger-point druzy, these finer crystals give a more delicate, sugar-like appearance.\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eThe base and outer edge display banded agate and quartz matrix, with natural inclusions and earthy mineral tones. This banding is characteristic of geode formations and provides insight into the layered mineral deposition over time.\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 surface\u003cbr\u003eNatural banding and mineral tones along the base\u003cbr\u003ePolished sides with a raw druzy crystal top\u003cbr\u003eNo visible dyeing or artificial enhancement\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003eCare Instructions\u003cbr\u003eHandle with care to avoid chipping the delicate crystal points\u003cbr\u003eClean gently using a soft brush or compressed air\u003cbr\u003eAvoid water exposure, 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":53659913093461,"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_9e3fc6f9-5924-44f4-b394-ebe64aacb065.jpg?v=1776347403","url":"https:\/\/crystalballerz.co.uk\/products\/amethyst-druzy-cupcake","provider":"Crystal Ballerz","version":"1.0","type":"link"}
