Not sure if this is the right place to ask this question but, here goes. I received a diamond pendant for Christmas and would like to know what type of chain is best for a diamond pendant? It is 1.65 carat. The chain that it came with is very nice and delicate but, though the salesperson assured my husband that it is strong, I am concerned and wanted your opinion. It has serveral small links and then a longer link following this pattern. I noticed that the ring connecting to the clasp did not appear to be soldered and wondered about that as well. Any thoughts or advice? Thanks for the help.
