{"product_id":"blue-kyanite-bracelet-old-mine-deep-blue-beads","title":"Blue Kyanite Bracelet — Old-Mine Deep Blue Beads","description":"\u003cp\u003eKyanite is the blue stone that behaves unlike any other bead on a bracelet: it measures about 4.5 on the Mohs scale along the length of the crystal and 6 to 7 across it. This strand is cut from older mine rough, which is why the blue runs deep and slightly uneven rather than flat and even the way dyed material does. Strung on a strong elastic core with no clasp.\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, old-mine 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\u003eFinish:\u003c\/strong\u003e Polished, untreated\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.

Kyanite is rarely dyed because the rough is already blue; what varies is how much black or green mineral runs through it. The colour comes from iron and titanium inside the crystal structure, not from a surface treatment.\u003c\/p\u003e\n\u003ch3\u003eHow does it fit?\u003c\/h3\u003e\n\u003cp\u003eThe strand is single loop on elastic with no clasp, and fits a wrist of roughly 15-18 cm (5.9-7.1 in). If you need a different length, message us before ordering and we will tell you what is in stock.\u003c\/p\u003e\n\u003ch3\u003eHow do I look after kyanite?\u003c\/h3\u003e\n\u003cp\u003eWipe with a soft dry cloth and store it away from harder stones. Kyanite is softer along one axis than across it, so a sharp knock can open a split. Skip ultrasonic cleaners.\u003c\/p\u003e\n\u003ch3\u003eHow long does delivery take?\u003c\/h3\u003e\n\u003cp\u003eOrders are processed in 1-3 business days from our Shenzhen studio.
