Bi-color tourmaline holds two colours in one crystal. As the October birthstone it makes a thoughtful gift, and at 7 to 7.5 on the Mohs scale it wears well. Its lively colour makes it a rewarding choice for a one of a kind design. Set it as a ring centre, drop it into a pendant, pair it in earrings, or keep it aside. This is a natural, earth mined stone, chosen by hand at NNJ Designs. Care: clean with warm, soapy water and a soft brush, and avoid harsh chemicals and ultrasonic cleaners.\u003c\/p\u003e","brand":"NNJ Designs","offers":[{"title":"Default Title","offer_id":48339478085830,"sku":"22874","price":169.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0052\/0601\/6071\/files\/9c785049-30b5-4660-a474-de3f3f361897.jpg?v=1792163533","url":"https:\/\/nnjdesigns.com\/products\/bi-color-tourmaline-n-em-8-5x7-6mm-3-13cts-single","provider":"NNJ Designs","version":"1.0","type":"link"}
