VCA will do it. Only have them work on the jewelry so they are responsible and can replace something if it's done wrong. My posts of ;my new earrings fell off 3 times. I was furious! i could have soldered them on. Just wear it at home a few times to make sure it doesn't fall off and it's fine. I do that with all my jewelry as a precaution. I was sitting watching tv with my new diamond fivole earrings (large) and one was on the couch. I was screaming. Imagine if I had been out. Then they fixed it put on new posts. It happened again, it wasn't lasered properly. Then the posts barely came out of my ear. Then they made them an inch long so they hit the back of my neck. Horrid. The jewelry store that sold them finally just cut them down for me. Very poor workmanship. Now I am going to have the posts changed on my large fleurette diamond earrings. They are too thin My SA said "you're hardly the only one! Each week there are people complaining about posts and they have to be replaced." I don't have their bracelets but that's another major source of complaints. Just have them solder it. And if you have earrings make sure the posts are soldered in, or lasered.
