Its purity doesn't come from any treatment but from the absence of coloring ions in the crystal lattice. In amethyst, iron ions sit there and make it look violet. Rock crystal has none. It crystallizes in the trigonal system as six-sided prisms, and with a Mohs hardness of 7, it is pleasantly durable for everyday wear. It typically shows a glassy luster on its natural crystal faces and a softer, greasy luster on broken surfaces, so the raw stone flashes in a new way whenever the light changes.\u003c\/p\u003e\n\n\u003ch2\u003eMaterial and Craftsmanship\u003c\/h2\u003e\n\u003cp\u003eYou can choose between 925 sterling silver and a warm 14K gold-filled setting. 14K gold-filled is a real, thick layer of gold that is firmly bonded to a base metal. Unlike simple gold plating, which is applied only wafer-thin, wears off over time, and fades fairly quickly, 14K gold-filled keeps its warm gold tone for years. The wire is wrapped by hand around each raw stone individually, so the setting follows the natural shape of your stone. The pendant hangs on a fine chain with closely interlocking links, so it lies smoothly against your neck. You choose the length when you order: 45 cm (17.7 in) or 40 cm (15.7 in).\u003c\/p\u003e\n\n\u003ch2\u003eMeaning of the Stone\u003c\/h2\u003e\n\u003cp\u003eIts name goes back to the Greek word krystallos, which means ice. In antiquity, people believed clear quartz was ice frozen so deeply that it could never thaw. For centuries, it was made into seals, lenses, and spheres. By tradition, it stands for clarity, purity, and an alert eye for what really matters. On the British birthstone list, rock crystal is a birthstone for April alongside diamond.\u003c\/p\u003e\n\n\u003ch2\u003eCaring for Your Rock Crystal Necklace\u003c\/h2\u003e\n\u003cp\u003eThe pendant and chain are water-resistant and suitable for everyday wear.

After swimming in the ocean or a pool, it's best to rinse the necklace with clean water and dry it carefully.\u003c\/p\u003e\n\n\u003cp\u003eRock crystal has no cleavage and breaks with a shell-like fracture. Even so, a hard knock on an edge can damage the raw stone. So store your necklace dry and apart from harder pieces of jewelry, and protect it from sudden changes in temperature. This way, the clarity of the stone and the shine of your setting will last for a long time.\u003c\/p\u003e","brand":"Handmade Art by Carola","offers":[{"title":"Gold \/ With chain \/ 45 cm","offer_id":55256566956361,"sku":"BER001-RING","price":95.0,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ With chain \/ 40 cm","offer_id":55256566989129,"sku":"BER001-RING","price":95.0,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ Pendant only \/ Pendant only","offer_id":55256567120201,"sku":"BER001","price":80.0,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ With chain \/ 45 cm","offer_id":55256567152969,"sku":"BER001-RING","price":90.0,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ With chain \/ 40 cm","offer_id":55256567185737,"sku":"BER001-RING","price":90.0,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ Pendant only \/ Pendant only","offer_id":55256567316809,"sku":"BER001","price":80.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/1419\/5003\/files\/1_6bbcc9ed-526b-417f-94dd-46724e15d2ed.png?v=1788586523"},{"product_id":"bergkristall-tropfen-kette","title":"Teardrop Rock Crystal Necklace","description":"\u003ch2\u003eThe Stone: Rock Crystal from the Quartz Family\u003c\/h2\u003e\n\u003cp\u003eRock crystal is the colorless variety of the mineral quartz, chemically pure silicon dioxide with the formula SiO2.
