{"product_id":"aquamarine-black-obsidian-bracelet-set-925-sterling-silver","title":"Aquamarine \u0026 Black Obsidian Bracelet Set — 925 Sterling Silver","description":"\u003cp\u003eThis set pairs pale blue aquamarine with jet-black obsidian — one light, one dark, designed to be worn together or split between two people. Both strands are strung on a strong elastic core and separated by 925 sterling silver spacers, so the metal that touches your skin is sterling, not plated brass.\u003c\/p\u003e\n\u003ch2\u003eWhat you receive\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eStones:\u003c\/strong\u003e Natural aquamarine and black obsidian\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMetal:\u003c\/strong\u003e 925 sterling silver spacers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBead size:\u003c\/strong\u003e 8 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength:\u003c\/strong\u003e Approx. 17–18 cm (6.7–7.1 in), elastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSet:\u003c\/strong\u003e Two bracelets\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eAbout aquamarine and obsidian\u003c\/h2\u003e\n\u003cp\u003eAquamarine is a blue variety of beryl, the same mineral family as emerald. Its colour ranges from pale ice-blue to a deeper sea-blue, and it measures 7.5–8 on the Mohs scale, which makes it durable enough for daily wear. Obsidian is volcanic glass, formed when lava cools so quickly that no crystals have time to grow.\u003c\/p\u003e\n\u003ch2\u003eFit and sizing\u003c\/h2\u003e\n\u003cp\u003eEach bracelet is strung on elastic and measures approximately 17–18 cm (6.7–7.1 in) unstretched, which fits most wrists. Because the core is elastic, the bracelet rolls on without a clasp. If you need a specific length, message us before ordering and we will confirm availability.\u003c\/p\u003e\n\u003ch2\u003eCare\u003c\/h2\u003e\n\u003cp\u003eWipe the beads with a soft dry cloth. Keep the bracelet away from perfume, hairspray and chlorinated water, and store it flat rather than hanging, so the elastic does not stretch between wears. Sterling silver spacers may darken over time; a silver polishing cloth restores their shine.\u003c\/p\u003e\n\u003ch2\u003eShipping and returns\u003c\/h2\u003e\n\u003cp\u003eOrders over $70 ship free. We accept returns within 30 days of delivery on unworn pieces in their original packaging.\u003c\/p\u003e\n\u003ch2\u003eCommon questions\u003c\/h2\u003e\n\u003ch3\u003eIs the aquamarine natural, and is it treated?\u003c\/h3\u003e\n\u003cp\u003eBoth stones are natural. Aquamarine is routinely heat-treated in the trade to remove a green cast, and most blue aquamarine sold today has been heated — heating is permanent and is accepted practice, not a coating. The obsidian is volcanic glass and is not treated at all. If you need fully untreated aquamarine, email us before ordering and we will tell you what is in stock.\u003c\/p\u003e\n\u003ch3\u003eWill an 8 mm bracelet fit my wrist?\u003c\/h3\u003e\n\u003cp\u003eEach bracelet measures about 17–18 cm (6.7–7.1 in) unstretched on 8 mm beads, which suits wrists from roughly 14.5 to 19 cm. There is no clasp to adjust — the elastic core lets it roll on. If your wrist measures outside that range, message us before ordering.\u003c\/p\u003e\n\u003ch3\u003eIs the silver solid or plated?\u003c\/h3\u003e\n\u003cp\u003eSolid 925 sterling silver spacers. Sterling is 92.5% silver, so the metal runs all the way through and can be polished back to brightness. Plated brass wears through to a yellow base layer within months of daily wear.\u003c\/p\u003e\n\u003ch3\u003eCan I wear the set in water?\u003c\/h3\u003e\n\u003cp\u003eOccasional hand-washing is fine. Take it off for swimming, hot tubs and chlorinated showers — chlorine dulls the silver and etches the obsidian polish over time.\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. Standard delivery to the US takes 10–20 business days and costs $8; shipping is free on orders over $70. Express delivery is $15. A tracking number is emailed once the parcel is handed to the carrier.\u003c\/p\u003e\n\u003ch2\u003eRelated reading\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/collections\/bracelets\"\u003eAll crystal bracelets\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/blogs\/crystal-encyclopedia\/aquamarine-crystal-guide-complete-meaning-properties-how-to-use-2026\"\u003eAquamarine crystal guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/blogs\/crystal-encyclopedia\/black-obsidian-crystal-guide\"\u003eBlack obsidian crystal guide\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/ja\/blogs\/journal\/sterling-silver-crystal-bracelet-guide\"\u003eWhy 925 silver matters on a bracelet\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n","brand":"Vincryst","offers":[{"title":"Default Title","offer_id":52477445177639,"sku":"VIN-CB-001","price":44.9,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0994\/2011\/1143\/files\/VIN-CB-001-01.jpg?v=1793264179","url":"https:\/\/vincryst.com\/ja\/products\/aquamarine-black-obsidian-bracelet-set-925-sterling-silver","provider":"Vincryst","version":"1.0","type":"link"}
