Question: I bought a 925 silver necklace. I think it is a little shorter and want to lengthen it, but I find that the circle is closed. What should I do? Answer: Because 925 silver necklaces are relatively soft and easy to be pulled apart, the circle is already welded to death when it is connected. If you want to lengthen the necklace, you can send it to a specialty store or silver jewelry factory. They can help you get it. Great.
