The colour comes from traces of copper within the tourmaline structure — the same element that gives the Paraiba family its glow, and the reason these stones are valued well above ordinary tourmaline. Brazil is where the variety was first found, and remains its most closely associated source. A practical size for a solitaire ring or pendant.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\"Small in carat, not in colour.\"\u003c\/em\u003e\u003c\/p\u003e","brand":"NNJ Designs","offers":[{"title":"Default Title","offer_id":46118247891142,"sku":"20950","price":392.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0052\/0601\/6071\/files\/4f53f43e-6af4-45af-8c11-febc9615f144.jpg?v=1784823436","url":"https:\/\/nnjdesigns.com\/products\/gia-paraiba-tourmaline-n-ov-7-81x5-83x3-68mm-1-09cts-6237977233","provider":"NNJ Designs","version":"1.0","type":"link"}
