This one is unheated — uncommon for sapphire, and the reason untreated material carries a premium. Sapphire is corundum, 9 on the Mohs scale and second only to diamond for hardness — which is why it holds up to daily wear better than almost any coloured stone. A practical size for a solitaire, or set in a group where a run of matched pinks is wanted.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\"Small stone, serious mineral.\"\u003c\/em\u003e\u003c\/p\u003e","brand":"NNJ Designs","offers":[{"title":"Default Title","offer_id":46483902398662,"sku":"14041","price":384.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0052\/0601\/6071\/files\/7-27-26-14041-PinkSapphire-2.jpg?v=1785177877","url":"https:\/\/nnjdesigns.com\/products\/natural-pink-sapphire-5-9x5-9mm-1-07cts-unheated-loose-gemstone-for-custom-jewellery-design","provider":"NNJ Designs","version":"1.0","type":"link"}
