Why has my jewellery turned black?
All sterling silver will tarnish over time, but it will happen much faster when it comes into contact with agents such as perfume, salty air, sulphur in the air, skin creams, hairspray, chlorine, sea water, perspiration, medication excreted through the skin, and acidic skin ph. Hot and humid conditions also stimulate tarnish. The amount of tarnishing (oxidation) that occurs is dependent on the skin and care habits of the wearer. Tarnishing is therefore not a manufacturing fault.
