About Silver 925 Pure silver is very soft and easily scratched or dented, making it somewhat difficult to use for accessories. Therefore, by mixing other metals with pure silver, it is reborn as practical silver accessories. About Metal Allergies Silver itself is said to be a metal that is unlikely to cause metal allergies, but whether or not an allergy occurs varies from person to person, so please refrain from using it if you experience any reaction. About Silver Accessory Care Silver reacts with sulfur components in the air and gradually darkens over time. This is a phenomenon that cannot be avoided when using silver.
