Omega Chain, Bead, Curb, Gemstone, Link, Box, Heart, Mesh, Rope Chain and more! Gold comes in many colors including white, yellow, red, and rose, and modern necklaces often include color combinations.
Pure gold is most often too soft to be crafted into jewelry, and so it is combined with other metals, which is also what accounts for the different colors. Rose gold comes from combining pure gold with copper; yellow gold is made by combining pure gold with both silver and copper, and white gold is made with a combination of silver and pure gold.
