Silver

Silver is white - grayish white, soft material, can make matte and bright effect, is a precious metal with a long history, and was once more expensive than gold, but now it is the cheapest precious metal. Generally used in jewellery is 925 silver, which means that the content of silver is 92.5%. Usually, a small amount of other metals such as copper and zinc are added to make it have the desired hardness. Although it is harder than pure silver, it is easily deformed and scratched. Since silver is easily oxidized in the air, it should be sealed and stored in a dry place when not worn, and it is usually wiped with a professional silver cloth.
