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 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 heart is cut from opal, a mineraloid made of hydrated silicon dioxide. Because its tiny silica gel spheres diffract light, it shows a lively play of color in green, blue, and violet. The opal is polished smooth and set in a gold bezel that protects its edge. Its Mohs hardness is 5.5 to 6.5, so it shouldn't take any hard knocks.\u003c\/p\u003e\n\n\u003ch2\u003eMaterial and Craftsmanship\u003c\/h2\u003e\n\u003cp\u003eThe setting, ring, and spring ring are made of 14K gold-filled, and the opal pendant is available in gold only. With 14K gold-filled, the gold layer is so substantial that your charm stays golden for a long time, even if you switch it around often. To attach the charm, push back the lever on the spring ring with your fingernail, guide the ring around a link, and release the lever. On a fine box chain, simply place the ring around the whole chain, and the heart will hang at the front, in the center. I assemble each opal charm by hand in my studio in Oberhausen and check that the spring ring snaps shut cleanly.\u003c\/p\u003e\n\n\u003ch2\u003eMeaning of Opal\u003c\/h2\u003e\n\u003cp\u003eOpal's reputation as an unlucky stone goes back to a novel from the 19th century. For long stretches of history, it was actually considered a lucky stone, because it carries all colors within it. And because opal is the birthstone for October, an opal pendant becomes a small symbol of good luck for everyone born in October.\u003c\/p\u003e\n\n\u003ch2\u003eCaring for Your Opal Pendant\u003c\/h2\u003e\n\u003cp\u003eThe spring ring and setting can handle water, but the opal should stay as dry as possible. If your opal pendant hangs on a bracelet, take it off before you wash your hands with soap, do the dishes, or shower. The sauna and direct sun aren't good for it either, because high heat can draw water out of it.\u003c\/p\u003e\n\n\u003cp\u003eTo clean it, use a soft, slightly damp cloth and then pat the heart dry. Ultrasonic cleaners, steam, and cleaning products are off-limits. Check now and then that the spring ring still snaps shut firmly, so your heart stays securely in place. A small pouch, away from harder jewelry, is ideal for storage.\u003c\/p\u003e","brand":"Handmade Art by Carola","offers":[{"title":"Gold","offer_id":55676461023561,"sku":"OPH-CHA-G","price":70.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/1419\/5003\/files\/opal-herz-charm-01-gold.jpg?v=1792454360"},{"product_id":"rosa-turmalin-kette-unikat","title":"Raw Pink Tourmaline Necklace","description":"\u003ch2\u003eThe Stone: Pink Tourmaline as a Raw Crystal\u003c\/h2\u003e\n\u003cp\u003eThis pink tourmaline necklace carries a genuine tourmaline in its natural crystal form.
