What's the difference between an old silver bracelet and a new one?

The old silver bracelet is different from the new one in the following aspects:

1. Purity: The purity of old silver is usually higher than that of new silver. The purity of old silver is generally sufficient silver, reaching 99%, while the purity of new silver is usually 92.5%.

2. Soft hardness: Because the purity of the old silver is relatively high and soft, it can't be beaten too thin, while the purity of the new silver is not as pure as the old silver, and it is harder and less brittle.

3. Glossy: The new silver bracelet has a high luster, with a faint white light unique to silver, while the old silver bracelet is dull.

4. Color: The new silver bracelet is lighter in color, while the old silver bracelet is darker or even darker.

5. Manufacturing technology: When making old silver bracelets, due to the technological limitations at that time, it is often necessary to add other metals to increase the hardness and stability, while new silver bracelets are usually made by more superb technology.

Generally speaking, there are obvious differences between the old and new silver bracelets in purity, hardness, luster, color and manufacturing technology.
