Quartz Small Heart Pendant - Gemstone 14K gold filled dainty chain - Minimalist, Romantic, Love Jewelry for her, wife, girlfriend Stone: Genuine Quartz Heart Gemstone: 10mm x 10mm Gold chain: 14k gold filled Chain length: 16-18 inches adjustable Clasp: spring ring Bezel: Vermeil Gold About "Gold Filled Jewelry": Also called rolled-gold. These jewelry items are not actually filled with gold. They are made of a base metal covered by sheets of gold in a mechanical bonding process. Effectively a thick coat of gold: the industry standard for the gold content is 5% or 1/20 of the total weight. Made with 14k gold, it is hard wearing. With reasonable care it will not peel or flake, and should last as long as solid 14k gold jewelry.
