{"product_id":"roher-schwarzer-turmalin-kette","title":"Raw Black Tourmaline Necklace","description":"\u003ch2\u003eThe Stone: Black Tourmaline, Known in Mineralogy as Schorl\u003c\/h2\u003e\n\u003cp\u003eBlack tourmaline has the mineralogical name schorl. Rich in sodium and iron, it is an end member of the tourmaline group, a family of complex boron ring silicates. Its black color doesn't come from dye but from iron that sits firmly in the crystal lattice. It crystallizes in the trigonal system and forms prismatic crystals with a triangular cross section and the lengthwise striations typical of this mineral group, which you can clearly see on this raw stone. With a Mohs hardness of 7 to 7.5, it is one of the more durable gemstones. The name schorl goes back to the village of Zschorlau in Saxony, where the mineral was described as early as the 16th century.\u003c\/p\u003e\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 raw stone measures about 8 to 10 mm. The pendant hangs on a fine chain, and you choose its length when you order: 45 cm (17.7 in) or 40 cm (15.7 in).\u003c\/p\u003e\n\u003ch2\u003eMeaning of the Stone\u003c\/h2\u003e\n\u003cp\u003eTourmaline builds up an electrostatic charge when it is heated or put under pressure, a pyroelectric and piezoelectric effect that people noticed as early as three hundred years ago. In the 18th century, Dutch sailors used it to pull ash out of their pipes and so gave the stone the nickname \"ash puller.\" By tradition, black tourmaline stands for protection, grounding, and level-headed clarity. As a birthstone for October, it also makes an especially personal gift.\u003c\/p\u003e\n\u003ch2\u003eCaring for Your Black Tourmaline Necklace\u003c\/h2\u003e\n\u003cp\u003eThe pendant and chain are water-resistant and suitable for everyday wear. To make your necklace last as long as possible, though, you should avoid prolonged contact with salt water and chlorinated water, as well as perfume, lotions, and harsh cleaning products. 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\u003cp\u003eSchorl shouldn't be cleaned in an ultrasonic cleaner or with steam, and it should be protected from high heat and sudden changes in temperature. Store your necklace dry and apart from softer pieces of jewelry, because the natural edges of the raw stone can scratch more delicate stones. This way, the fine striations of the stone and the surface of your necklace will stay beautiful for a long time.\u003c\/p\u003e","brand":"Handmade Art by Carola","offers":[{"title":"Gold \/ With chain \/ 45 cm","offer_id":55256583569737,"sku":"TUR001","price":149.0,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ With chain \/ 40 cm","offer_id":55256583602505,"sku":"TUR001","price":139.0,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ With chain \/ Pendant only","offer_id":55256583635273,"sku":"TUR001","price":149.0,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ Pendant only \/ 45 cm","offer_id":55256583668041,"sku":"TUR001","price":79.0,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ Pendant only \/ 40 cm","offer_id":55256583700809,"sku":"TUR001","price":79.0,"currency_code":"EUR","in_stock":true},{"title":"Gold \/ Pendant only \/ Pendant only","offer_id":55256583733577,"sku":"TUR001","price":79.0,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ With chain \/ 45 cm","offer_id":55256583766345,"sku":"TUR001","price":119.0,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ With chain \/ 40 cm","offer_id":55256583799113,"sku":"TUR001","price":119.0,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ With chain \/ Pendant only","offer_id":55256583831881,"sku":"TUR001","price":119.0,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ Pendant only \/ 45 cm","offer_id":55256583864649,"sku":"TUR001","price":69.0,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ Pendant only \/ 40 cm","offer_id":55256583897417,"sku":"TUR001","price":69.0,"currency_code":"EUR","in_stock":true},{"title":"Silver \/ Pendant only \/ Pendant only","offer_id":55256583930185,"sku":"TUR001","price":69.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/1419\/5003\/files\/1_2672a090-cae5-4b86-8975-2b7d6100a67b.png?v=1788587583","url":"https:\/\/by-carola.com\/en\/products\/raw-black-tourmaline-necklace","provider":"Handmade Art by Carola","version":"1.0","type":"link"}
