Hello Knotties! I haven't been active on this board hardly at all (college+work+family issues) but I sure would appreciate some advice!
My fiance and I got engaged in December, and my ring is a lovely cushion-cut opal center stone surrounded by little diamonds on a white gold 4-prong setting. However, I've been having problems with the setting coming loose. At first the opal came loose because I snagged it on my sweater and it twisted in the setting. I took it to a jewlery repair and they tightened the setting for me. Twelve days later, the stone twisted again (luckily I noticed it before it fell out!). I am extra careful with my ring--I don't sleep in it, get it wet, bump/bang/drop/snag it, play with it...
After a little research, I have discovered that opals naturally contain water and therefore can change in size slightly with variations in temperature and humidity. Unfortunately for me, this means that no matter how many times I take it in to be tightened, it will continue to come loose. I don't want to damage it by continued tightenings of the setting, but I don't want to risk losing the stone! I hate not being able to wear my ring, but I just don't know what to do! My fiance is completely opposed to changing the setting or getting a new ring ("This is what you wanted!") so that's not going to happen... Can anyone help me come up with a solution to my problem?
