{"product_id":"sterling-silver-blue-and-green-tourmaline-faceted-necklace-aaa-grade","title":"Sterling Silver Bi Colour Tourmaline Faceted Necklace | AAA Grade","description":"\u003cp\u003eBi colour tourmaline is among the most visually compelling stones in the mineral world. Where most gemstones offer a single tone, this variety holds two within a single crystal here, a shift from cool blue into verdant green, the transition gradual and seamless, as though the stone itself could not decide where one colour ended and the other began.\u003c\/p\u003e\n\u003cp\u003eTourmaline belongs to a complex boron silicate mineral group, and it is this chemical intricacy that gives it such an extraordinary range of colour. The blue-to-green gradient occurs as the concentration of iron and copper within the crystal changes during formation, each shift in chemistry leaving its mark in colour. The result is a stone that is entirely natural and entirely unrepeatable.\u003c\/p\u003e\n\u003cp\u003eBlue tourmaline known also as indicolite, has long been associated with clarity of thought, calm, and honest communication. It is said to work with the throat and third eye chakras, encouraging stillness and perspective. The green carries its own energy: growth, renewal, and a grounded connection to the natural world. Together in a single stone, they offer something quietly rare, a balance of mind and heart, of expression and intuition.\u003c\/p\u003e\n\u003cp\u003eThis necklace features a rectangular faceted bi colour tourmaline measuring 10mm x 5mm (not including bail), the cut chosen to draw out the stone's natural gradient and allow light to move through it with depth and clarity. It is set in sterling silver and suspended on an 18 inch fine silver curb chain, a classic, lightweight length that sits beautifully at the collarbone.\u003c\/p\u003e\n\u003cp\u003eA stone worth looking at for a long time, and a piece worth wearing for longer.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eArrives gift-ready.\u003c\/em\u003e\u003c\/p\u003e","brand":"Rachel Hartley Atelier","offers":[{"title":"Default Title","offer_id":64538618888541,"sku":null,"price":135.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1061\/2909\/7053\/files\/image4_99d09023-f4aa-488a-9e02-97f474db0a51.jpg?v=1777311494","url":"https:\/\/rachelhartley.co.uk\/products\/sterling-silver-blue-and-green-tourmaline-faceted-necklace-aaa-grade","provider":"Rachel Hartley Atelier","version":"1.0","type":"link"}
