Heat treatment is standard practice for sapphire, permanent and stable, and this stone is disclosed as heated. 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":46483992608966,"sku":"17160","price":190.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0052\/0601\/6071\/files\/6a715f2f-bb6b-4f2f-84bc-12c3f57c3d73.jpg?v=1785155696","url":"https:\/\/nnjdesigns.com\/products\/natural-pink-sapphire-oval-6-8x4-8mm-0-66cts-heat-treated-loose-gemstone-for-a-custom-ring","provider":"NNJ Designs","version":"1.0","type":"link"}
