{"product_id":"brecciated-amethyst-polished-tower","title":"Brecciated Indian Amethyst Polished Tower","description":"\u003cp\u003eThis brecciated amethyst tower is a visually complex quartz specimen formed through natural fracturing and re-cementation processes. It features angular fragments of amethyst set within a silica-rich matrix, creating a mosaic-like internal structure. The combination of purple amethyst, milky quartz, and iron-stained sections gives this piece strong contrast and depth from every angle.\u003c\/p\u003e\n\u003cp\u003ePolished into a tower shape, the surface enhances clarity while preserving the raw internal textures, fractures, and mineral boundaries that define brecciated material.\u003c\/p\u003e\n\u003cp\u003eKey Features\u003c\/p\u003e\n\u003cp\u003eMineral: Quartz (Amethyst variety)\u003c\/p\u003e\n\u003cp\u003eChemical Formula: SiO₂\u003c\/p\u003e\n\u003cp\u003eFormation: Brecciated quartz (fractured and naturally re-bonded)\u003c\/p\u003e\n\u003cp\u003eColour: Purple, white, translucent quartz with reddish-brown iron staining\u003c\/p\u003e\n\u003cp\u003eTransparency: Translucent to opaque\u003c\/p\u003e\n\u003cp\u003eLustre: Vitreous (glassy)\u003c\/p\u003e\n\u003cp\u003eCrystal System: Trigonal\u003c\/p\u003e\n\u003cp\u003eMohs Hardness: 7\u003c\/p\u003e\n\u003cp\u003eFinish: Polished freeform\u003c\/p\u003e\n\u003cp\u003eDimensions\u003c\/p\u003e\n\u003cp\u003eSize: 5 cm x 3.5 cm\u003c\/p\u003e\n\u003cp\u003eWeight: 72 grams\u003c\/p\u003e\n\u003cp\u003eGeological \u0026amp; Scientific Notes\u003c\/p\u003e\n\u003cp\u003eBrecciated amethyst forms when pre-existing quartz (including amethyst) undergoes fracturing, typically due to tectonic activity or pressure changes within the host rock. These broken fragments are later naturally cemented back together by silica-rich fluids, which solidify to form a new quartz matrix.\u003c\/p\u003e\n\u003cp\u003eThe reddish-brown areas seen throughout this piece are caused by iron oxide inclusions, which commonly occur during later stages of mineralisation. The variation between translucent quartz and opaque zones reflects differences in crystal growth conditions, impurity content, and fracture healing.\u003c\/p\u003e\n\u003cp\u003eAmethyst’s purple colour is the result of trace iron (Fe³⁺) within the quartz structure, altered by natural irradiation over time.\u003c\/p\u003e\n\u003cp\u003eWhy This Piece Stands Out\u003c\/p\u003e\n\u003cp\u003eStrong brecciated structure with clearly defined angular fragments\u003c\/p\u003e\n\u003cp\u003eNatural contrast between amethyst, quartz, and iron-rich matrix\u003c\/p\u003e\n\u003cp\u003eVisible fracture patterns and healed crystal boundaries\u003c\/p\u003e\n\u003cp\u003eA solid, weighty display piece with good structural definition\u003c\/p\u003e\n\u003cp\u003eCare\u003c\/p\u003e\n\u003cp\u003eClean with lukewarm water and mild soap\u003c\/p\u003e\n\u003cp\u003eAvoid prolonged exposure to strong sunlight (may reduce colour intensity over time)\u003c\/p\u003e\n\u003cp\u003eStore separately to prevent scratching softer minerals\u003c\/p\u003e","brand":"Crystal Ballerz","offers":[{"title":"Default Title","offer_id":53776891052373,"sku":null,"price":22.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1039\/9295\/1125\/files\/rn-image_picker_lib_temp_353c1735-5ded-456a-a5a1-3b03a8060c5e.jpg?v=1777294351","url":"https:\/\/crystalballerz.co.uk\/products\/brecciated-amethyst-polished-tower","provider":"Crystal Ballerz","version":"1.0","type":"link"}
