Gold is a precious metal that does not oxidize or tarnish as most other metals do. Gold is very malleable and can be melted and cast into both small and large objects. Gold is alloyed with other metals like silver, copper or nickel to make it harder. The ratio of gold to other metals is what denotes the karat content, such as 14k, 18k and 22k Gold. Our Gold Cufflinks like yellow gold cufflinks and designer gold cufflinks are made of 18k Yellow & White Gold and these are studded with natural stones & diamonds.
