Third-grade specimens are selected for their natural formation and display appeal rather than depth of colour; expect nearly clear to pale lavender hues with the same distinctive crystal structure that makes amethyst a perennial favourite. The cut base allows each piece to stand freely without a mount or stand.\u003c\/p\u003e\n\u003ch4\u003ePhysical Properties\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMineral:\u003c\/strong\u003e Amethyst (SiO₂ — Silicon Dioxide, variety of Quartz)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHardness:\u003c\/strong\u003e 7 Mohs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCrystal System:\u003c\/strong\u003e Trigonal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLustre:\u003c\/strong\u003e Vitreous\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTransparency:\u003c\/strong\u003e Transparent to translucent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColour:\u003c\/strong\u003e Pale lavender to light violet (third grade)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eGeology \u0026amp; Formation\u003c\/h4\u003e\n\u003cp\u003eUruguayan amethyst forms within ancient basaltic geodes, shaped over millions of years by silica-rich hydrothermal fluids. The violet colouration results from trace iron impurities and natural irradiation within the crystal lattice. Uruguay is globally recognised as a premier amethyst source; third-grade material from this origin still carries the hallmark dense crystal formation and structural integrity the region is known for — the colour is simply lighter than premium grades.\u003c\/p\u003e\n\u003ch4\u003eCrystal Properties\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eProtection\u003c\/strong\u003e — said to create a shield of spiritual light around the body and environment\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePurification\u003c\/strong\u003e — traditionally used to cleanse the energy of a space and promote calm clarity\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntuition\u003c\/strong\u003e — associated with the third eye chakra; believed to strengthen inner wisdom and higher guidance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSleep \u0026amp; Stress\u003c\/strong\u003e — widely regarded as one of the most supportive crystals for restful sleep and anxiety relief\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eSpecimen Details\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Cluster, cut base for freestanding display\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Uruguay\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGrade:\u003c\/strong\u003e Third grade — lighter colour, natural character\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eWeight \u0026amp; Dimensions:\u003c\/strong\u003e\u003cstrong\u003e\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003e1. 360g, 85 x 65 x 53mm\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e2. 990g, 111 x 112 x 110mm\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e3. 970g, 130 x 80 x 75mm\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e4. 990g, 102 x 102 x 96mm\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e5. 635g, 111 x 84 x 80g\u003c\/strong\u003e\u003cbr\u003e\u003cstrong\u003e6. 975g, 120 x 80 x 73mm\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"The Rock \u0026 Fossil Shop","offers":[{"title":"1","offer_id":54702773731661,"sku":"GYZIJ","price":10.0,"currency_code":"GBP","in_stock":true},{"title":"2","offer_id":54702773764429,"sku":"BUCTQ","price":25.0,"currency_code":"GBP","in_stock":true},{"title":"3","offer_id":54702773797197,"sku":"DEQVB","price":28.0,"currency_code":"GBP","in_stock":true},{"title":"4","offer_id":54702773829965,"sku":"TARNV","price":25.0,"currency_code":"GBP","in_stock":true},{"title":"5","offer_id":54702773862733,"sku":"LBXCH","price":18.0,"currency_code":"GBP","in_stock":true},{"title":"6","offer_id":54702773895501,"sku":"RKQYC","price":25.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0982\/0120\/7117\/files\/Amethyst_Cut_Base_3rd_Grade_All_GYZIJ.jpg?v=1788974171","url":"https:\/\/www.rockandfossilshop.co.uk\/products\/amethyst-cluster-with-cut-base-free-standing-3rd-grade","provider":"The Rock \u0026 Fossil Shop","version":"1.0","type":"link"}
