{"product_id":"amethyst-quartz-variety-crystal-cluster-6-5-4-cm-130g","title":"Amethyst Quartz Variety Crystal Cluster  | 6×5×4 cm | 130g","description":"\u003cp dir=\"auto\" class=\"PDq2pG_selectionAnchorContainer\"\u003eThis particular specimen is a natural cluster of \u003cstrong\u003eAmethyst, the violet-to-purple variety of Quartz\u003c\/strong\u003e, showing numerous closely intergrown crystals with pale lilac to soft purple coloration and a glassy luster. Amethyst develops when silica-rich fluids deposit Quartz within open cavities, while small amounts of iron incorporated during crystal growth contribute to the color; natural irradiation activates the iron-related color centers that produce the characteristic violet appearance. The cluster displays repeated crystal growth with individual faces, natural contacts, inclusions, and variations in transparency across the formation, giving the specimen its distinctive three-dimensional character. Amethyst commonly occurs as crystal clusters rather than isolated crystals, making formations such as this particularly suitable for mineral collections. \u003cspan class=\"contents\"\u003e\u003cspan class=\"\"\u003e\u003c\/span\u003e\u003c\/span\u003e\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp dir=\"auto\"\u003e\u003cstrong\u003eSize:\u003c\/strong\u003e 6 × 5 × 4 cm\u003cbr\u003e\u003cstrong\u003eWeight:\u003c\/strong\u003e 130 g\u003cbr\u003e\u003cstrong\u003eSKU:\u003c\/strong\u003e MTX-B148-N742\u003c\/p\u003e","brand":"Matrix India Minerals","offers":[{"title":"Default Title","offer_id":50442204938496,"sku":"MTX-B148-N742","price":60.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0854\/9967\/4880\/files\/2_bf92799c-e6a3-4243-b921-38a2690d24e7.png?v=1790141846","url":"https:\/\/crystalshoponline.com\/products\/amethyst-quartz-variety-crystal-cluster-6-5-4-cm-130g","provider":"Matrix India Minerals","version":"1.0","type":"link"}
