You can't buy silver jewelry just by looking at whether there are thousands of silver characters. Many unscrupulous merchants can put these three words on the lack of purity or even fakes. Any place where precious metals are recycled will not only read the words, but also have special instruments to detect the purity of precious metals. Ordinary consumers have no ability to distinguish between true and false, so they can only choose to buy silver ornaments in more formal and reputable counters or specialty stores. Shun An Deyu is a good brand. If you buy it in a formal place, you can rest assured.
