{"product_id":"blue-kyanite-cats-eye-bracelet-brazilian-stone","title":"Blue Kyanite Cat's Eye Bracelet — Brazilian Stone","description":"\u003cp\u003eCut across the grain, blue kyanite shows a narrow band of light that shifts as the bead turns. This strand is Brazilian material, strung as a single loop on elastic so it rolls on without a clasp. The stone is untreated, and the band of light is a reflection off the parallel crystal fibres rather than a coating.\u003c\/p\u003e\n\u003ch2\u003eWhat you receive\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStone:\u003c\/strong\u003e Natural blue kyanite, Brazilian rough\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBracelet type:\u003c\/strong\u003e Single loop, elastic, no clasp\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFit:\u003c\/strong\u003e Approx. 15-18 cm (5.9-7.1 in) wrist\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptical effect:\u003c\/strong\u003e Cat's eye from parallel fibre structure\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout kyanite\u003c\/h2\u003e\n\u003cp\u003eKyanite is aluminium silicate, one of three minerals that share the same chemistry but form at different pressures — the others are andalusite and sillimanite. Its hardness is unusual: about 4.5 along the length of the crystal and 6 to 7 across it, because the atomic layers run in one direction. The blue comes from iron and titanium inside the structure. Kyanite is normally sold untreated; the fibrous pieces that show a moving band of light are cut across the grain.\u003c\/p\u003e\n\u003ch2\u003eFit and sizing\u003c\/h2\u003e\n\u003cp\u003eIt is a single loop, elastic bracelet on elastic with no clasp, and fits approx. 15-18 cm (5.9-7.1 in) wrist. Because the core is elastic it rolls on over the hand, so there is nothing to fasten one-handed. If you need a specific length, message us before ordering and we will tell you what is in stock.\u003c\/p\u003e\n\u003ch2\u003eCare\u003c\/h2\u003e\n\u003cp\u003eKyanite is softer along one axis, so it scratches and splits more easily in that direction than a quartz bead of the same size. Wipe with a soft dry cloth, keep it away from harder stones in a jewellery box, and avoid ultrasonic cleaners, which can open the cleavage.\u003c\/p\u003e\n\u003ch2\u003eShipping and returns\u003c\/h2\u003e\n\u003cp\u003eOrders are processed in 1-3 business days from our Shenzhen studio.

Cut across them, light reflects off the fibre walls and returns as a single bright band that moves with the bead. It is an optical property of the stone, not a coating or a finish.\u003c\/p\u003e\n\u003ch3\u003eIs this treated?\u003c\/h3\u003e\n\u003cp\u003eNo. Kyanite is normally sold untreated because the rough is already blue. Expect slight variation in tone between beads and a little black or green mineral running through some of them.\u003c\/p\u003e\n\u003ch3\u003eWill it fit my wrist?\u003c\/h3\u003e\n\u003cp\u003eThe bracelet is single loop elastic and fits roughly 15-18 cm (5.9-7.1 in). Message us if your wrist is outside that range.\u003c\/p\u003e\n\u003ch3\u003eHow should I clean it?\u003c\/h3\u003e\n\u003cp\u003eWipe with a soft dry cloth. Avoid ultrasonic cleaning, which can open the cleavage along the soft axis. Store away from harder stones.\u003c\/p\u003e\n\u003ch2\u003eRelated reading\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/new-arrivals\"\u003eNew arrivals\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/bracelets\"\u003eAll crystal bracelets\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/blogs\/journal\/sterling-silver-crystal-bracelet-guide\"\u003eSterling silver bracelet guide\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Vincryst","offers":[{"title":"Default Title","offer_id":52480343867687,"sku":"VIN-CB-012","price":29.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/2011\/1143\/files\/VIN-CB-012-01.jpg?v=1793289420","url":"https:\/\/vincryst.com\/products\/blue-kyanite-cats-eye-bracelet-brazilian-stone","provider":"Vincryst","version":"1.0","type":"link"}
