{"product_id":"opal-herz-kette","title":"Opal Heart Necklace","description":"\u003ch2\u003eOpal: A Heart Full of Color\u003c\/h2\u003e\n\u003cp\u003eOpal is a mineraloid made of hydrated silicon dioxide, with the formula SiO2·nH2O. Unlike most gemstones, it does not form crystals but is amorphous. Inside it, tiny spheres of silica gel are packed closely and evenly. When light enters, it is diffracted by these spheres and split into spectral colors, which creates the typical play of color. For this opal necklace, the stone is cut as a smooth, heart-shaped cabochon. Across its milky white base, flashes of green, blue, violet, and soft orange appear, in a different spot with every movement.\u003c\/p\u003e\n\n\u003ch2\u003eMaterial and Craftsmanship\u003c\/h2\u003e\n\u003cp\u003eThe opal necklace is available in gold only, made of 14K gold-filled. A smooth bezel surrounds the heart all the way around and protects its delicate edge. With 14K gold-filled, a substantial gold layer is permanently bonded to a base metal. It wears off much more slowly than simple gold plating and keeps a warm tone even after years. The pendant glides on a box chain through an elongated bail. The chain's fine, square links lie smoothly on your skin and hardly twist. I assemble each opal necklace by hand in my studio in Oberhausen. When you order, you choose between 45 cm (17.7 in) and 40 cm (15.7 in).\u003c\/p\u003e\n\n\u003ch2\u003eMeaning of Opal\u003c\/h2\u003e\n\u003cp\u003eIn the first century, the Roman scholar Pliny the Elder wrote that some opals hold a play of color that rivals the richest colors of painters. He saw the colors of many other gemstones united in it. For October babies, opal is the stone of their birth month. With its heart-shaped stone, this opal necklace becomes a sign of affection.\u003c\/p\u003e\n\n\u003ch2\u003eCaring for Your Opal Necklace\u003c\/h2\u003e\n\u003cp\u003eThe 14K gold-filled chain is water-resistant, but it's better to keep the opal dry. It contains bound water and is sensitive to heat, sudden changes in temperature, and chemicals. So take your opal necklace off before the shower, the pool, or the sauna, and put it back on only once your lotion and perfume have fully soaked in.\u003c\/p\u003e\n\n\u003cp\u003eOn the Mohs scale, opal reaches only 5.5 to 6.5, which makes it one of the softer gemstones. Protect it from hard knocks and store the necklace in a soft pouch, apart from other jewelry. A soft, slightly damp cloth is all you need for cleaning. Ultrasonic cleaners and steam are off-limits for opal.\u003c\/p\u003e","brand":"Handmade Art by Carola","offers":[{"title":"Gold \/ 45 cm","offer_id":55676454240585,"sku":"OPH-KET-G45","price":193.0,"currency_code":"USD","in_stock":true},{"title":"Gold \/ 40 cm","offer_id":55676454273353,"sku":"OPH-KET-G40","price":193.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0744\/1419\/5003\/files\/opal-herz-kette-01-gold.jpg?v=1792454107","url":"https:\/\/by-carola.com\/en-int\/products\/opal-heart-necklace","provider":"Handmade Art by Carola","version":"1.0","type":"link"}
