All of our rope chain necklaces are made with genuine, solid 14K gold or sterling silver, meaning that they are made with 14k gold or sterling silver inside and out and are NOT hollow. They consist of two or more strands, twisted around each other resembling a rope. This style is one of our most popular men's necklaces. To get these silver and gold chains to glisten under the light, manufacturers use diamond cutters to create small facets, similar to diamonds, in the metal, which create a sparkle when the light hits them. Many rope chains have diamond cuts. GoldenMine offers an assortment of high quality rope silver chains, yellow and white gold chains, and two tone gold chains. You can also find other gold chain styles, such as gold figaro chains, mariner, and Cuban silver chains, at prices that you can afford.
