Oxidised sterling silver
has a lovely matte black surface with a gun metal lustre. The process of oxidising silver turns the metal's surface black. This treatment is called a patina which is a surface treatment and does not change the internal characteristics of the metal. As any surface treatment, it will wear off over time and use to show the metal underneath.
This will happen at varying speeds depending on how regularly the piece is worn and how much it rubs against clothes and skin. When you purchase an oxidised piece, expect it to wear back and polish up, so relax and enjoy the way its surface evolves over time.
The hand made nature of this product means that each item is unique.
