Oxidised Silver

Oxidised Silver

Oxidised silver is a type of silver that has undergone a process in which the surface is treated to create a darker, oxidised appearance. This is usually achieved by using sulphur or chemical solutions that react with the silver, giving it a characteristic black or grey colour. The oxidation can also highlight details in the design, making jewellery and other objects more attractive.

History

Silver has been used for thousands of years, but the technique of oxidising silver became popular in the 1900s, particularly within jewellery design. Artists and craftsmen began experimenting with oxidation to give traditional jewellery new aesthetic expressions. Oxidised silver was quickly recognised as a stylish and modern approach to jewellery design, and has since become a favourite among both designers and collectors.

Identification

To recognise oxidised silver, look for the characteristic dark surface, which often has high contrast against polished areas of the metal. There may also be small details in the design that are highlighted by the oxidation. Quality silver will often be hallmarked with "925" or "Sterling", indicating that it consists of 92.5% pure silver.

Collector's Value

Oxidised silver has gained increasing popularity among collectors in recent decades. Objects made of oxidised silver can vary considerably in value depending on factors such as the artist's reputation, the age of the piece and its craftsmanship quality. Generally speaking, unique or handmade pieces with intricate details are considered to have higher collector's value than mass-produced items.
