My jeweler has strongly recommended that I have my rings soldered together after the wedding. He is also a good family friend, so I do trust his opinion. He said that it greatly reduces "wear and tear" from the rings rubbing together.
At first, I was all for it. I really can't think of many scenarios where I would really need to wear only one of the rings. But now, i'm second guessing it. I kind of like knowing that i would at least have the option of taking one off but not the other, should the need arise (even if it never actually does). But of course I also want to protect my rings as best as I can.
Did you solder yours together? If so, are you happy with it? If you didn't, why not?
