Made of 925 silver.
Blackened Silver: Silver can be treated with an oxide. The tincture causes an extreme tarnishing of the silver, it becomes black and the use of the piece is anthracite. This anthracite is relatively resistant and not harmful to health. It takes off after some time, but most of it on the edges. We find the wear marks lend the piece of jewelry a character rather than a quality loss. The piece of jewelery can be blackened at any time.
