Silver tarnish is inevitable, and will eventually happen over few or many years - depending on various factors.
At Sandbox we solely work with and offer 925 sterling silver. However, generically speaking, customers must avoid silver pieces that are below the 925 sterling silver quality mark. 925 silver translates to 92.5% of the piece being silver, and the other 7.5% of the mixture being copper/brass.
Exposing silver pieces to water will NOT affect the silver.
STERLING SILVER CARE
1. High humidity
2. Air Pollution
3. Silver pieces having constant exposure to air without being worn; silver reacts to the sulfur in the air. This occurs slowly, and is more prone to happening if the silver piece is not worn regularly.
4. Chemicals found in products such as hairspray, perfumes, deodorant, bleach. Tarnish here develops as a chemical reaction.
5. High levels of salt in the body
1. Constantly wear the silver piece. Creating constant direct contact with the skin leaves little room for the development of tarnish. This constitutes to whether your silver piece last 2 years or 20 years before tarnishing. Frequently handling it, significantly lessens from tarnish development.
Disclaimer: This prevention measure does not apply to those who have high levels of salt in their body; on the contrary, this will have the opposite effect.
2. When not worn, store the silver piece in an airtight space.
3. Avoid exposing your silver pieces to liquids composed of chemicals, such as the ones mentioned above under the "Tarnish causes" section.
If the prevention measures mentioned above are taken, the silver piece(s) will last years without getting tarnished.
