Blue Lace Agate Gold Pendant Necklace - Elongated Oval Genuine Gemstone Pendant on 14k Gold Filled Beaded Satellite Chain - Jewelry Gifts Stone: Genuine Blue Lace Agate and Topaz Please note due to nature of our genuine stones no two are alike and the ones you will receive will vary slightly from the ones pictured in the photos. Bezel: Vermeil Gold Chain: 14k Gold Filled, available in 18, 20 and 24 inches, satellite chain with spring ring clasp Gemstone: 13mm wide x 27mm height 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. It is safe for most people with sensitive skin.
