The pieces carry natural surface texture across irregular crystal faces, and the characteristic color of Madagascar corundum shifts between pink and a deeper berry-rose depending on the light direction. Each crystal has its own shape and internal pattern, reflecting the natural growth conditions of the mineral deposit.\u003c\/p\u003e\n\n\u003cp\u003eMadagascar accounts for the majority of the world's commercial ruby supply, and these crystals come directly from the island's ruby-bearing regions as raw, untreated rough. No heat or other enhancement has been applied, preserving the stones exactly as extracted from the deposit. Semi-transparent rough rubies in this size range are popular for wire-wrap jewellery, raw gemstone collections, mineral specimen display, and crystal-form jewellery design. Strong natural fluorescence under UV light is also characteristic of Malagasy ruby corundum.\u003c\/p\u003e\n\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone type:\u003c\/strong\u003e Natural ruby (corundum)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTreatment:\u003c\/strong\u003e Untreated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut\/Form:\u003c\/strong\u003e Rough crystal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 5-6mm per piece\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 4.61ct (5 pieces)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eClarity:\u003c\/strong\u003e Semi-transparent\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrigin:\u003c\/strong\u003e Madagascar\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eNatural ruby rough crystals, July birthstone - sold loose, 5 pieces.\u003c\/p\u003e","brand":"Lapis Magica","offers":[{"title":"Default Title","offer_id":58097543905605,"sku":"ru319-3","price":6.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/8576\/8517\/files\/5pcs-natural-ruby-4.61ct-untreated-rough-crystals.jpg?v=1780783870","url":"https:\/\/lapismagica.com\/products\/5-pieces-natural-ruby-4-61ct-untreated-rough-crystals","provider":"Lapis Magica","version":"1.0","type":"link"}
