All jewelry pieces from Love by hazel are made with Sterling Silver. Silver is a precious metal, but is also a very soft metal and therefore it is often mixed with another metal or alloy, usually copper to make it more durable. This is true of Sterling Silver which is made up of 92.5% silver and 7.5% copper. While the addition of copper is necessary to add support to the silver, it is also responsible for the tarnishing of sterling silver. It is important to recognize that this is not a defect in the jewelry, but a result of the oxidation of the copper.
