That is why you have wedding band... normal occasion wife won't wear diamond ring... just the wedding band...

Maybe I met a more straight forward sales guy when buying, straight away when choosing ring, he already mentioned that there is no guarantee and shit do happens, 6 claws 8 prong or 10 prong, if you drop it, hit it, linen caught it, there is always a chance it will come off.

But as many have mentioned, diamond has no value. So just let it be. Things happened cannot be undone. My suggestion, if you still have some money, buy another diamond, no need to be GIA certified, no one cares, and also no need to have the best colour and clarity, just choose the bigger (carat) will do
