100% pure silver is too soft for wearing; therefore, it is usually alloyed with other metals to make it more durable. It is the alloy of copper that causes Sterling Silver to darken over time. Sunshine, oxygen, skin oils, pollutants, and moisture in the air are the triggers that cause the chemical reactions that tarnish silver.
With proper care, silver doesn’t require routine cleanings.
Gemstones are all on a different hardness scale and depending on the gemstone, some can be more prone and sensitive to scratches. If minor scratches appear on some of your gemstone pieces, they can be polished out in most cases. Hot water and harsh chemicals should be avoided at all times when handling gemstones unless they are specifically made for gemstones.
