Green gold is a special gold alloy with a greenish shimmer that is created by a special atomic ratio of gold to silver. This alloy is occasionally used in jewelry making, especially for elaborate designs such as mokume gane wedding rings.
Shibuichi - Japanese alloy from the 7th century
Mokume Gane is a traditional Japanese forging technique dating back to the 17th century, in which different metals are fused in layers to create unique, wood grain-like patterns. This technique is often used in jewelry such as wedding rings. The combination of metals such as white gold, yellow gold, rose gold, platinum and palladium creates robust and aesthetically pleasing unique pieces. Mokume Gane reflects the Japanese aesthetic that finds beauty in simplicity and imperfection and is now popular with artists and metalsmiths worldwide.
