Materials
All products are made out of recycled sterling silver, the goldplated items are goldplated with either 18K gold or 24K gold. The chains are sterling silver. (If the description of the product states that some other material was used in it then that is what it is made of)
Sterling silver is a fairly soft material so if you want it to last shiny, bright and without scrapes as long as possible I recommend taking the jewelry off when the jewelry is likely to be exposed and clash with other metals or exposed to strong chemicals of any sort.
