Copper-bearing tourmaline is prized for a luminous blue-green that no other gem quite matches; in this stone the colour also shifts as the light changes, a behaviour uncommon enough in Paraiba material to make it a collector's piece. The oval measures 8.23 x 6.97 x 5.14 mm, deep enough to hold colour well in a bezel or claw setting.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003e\"Copper in the crystal, light in the colour.\"\u003c\/em\u003e\u003c\/p\u003e","brand":"NNJ Designs","offers":[{"title":"Default Title","offer_id":46118243565766,"sku":"20946","price":745.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0052\/0601\/6071\/files\/d96c2c57-e988-4849-b369-c4fa01026b6b.jpg?v=1784823392","url":"https:\/\/nnjdesigns.com\/products\/gia-color-change-paraiba-tourmaline-n-ov-8-23x6-97x5-14mm-2-07cts-2235977234","provider":"NNJ Designs","version":"1.0","type":"link"}
