DIAMONDS, your diamond, may not be forever
Today my wife lost the diamond out of her ring. She is UPSET! Ladies, check your ring, here is how. A simple eyeball check is way better than nothing, any sort of magnifier check is much better. Each prong should have a hook on the end hooking around the edge of the diamond. The hooks should be down tight! Any space at the end can let a thread snag and loosen the hook. The hooks can be raised on the end (bad), cut by the diamond so they are loose, or just plain worn short or gone from bumping into things.
It's a good idea to have a jeweler check your ring every once in a while, most will do it for free.
Sure you can buy another diamond, but it will not be "the" diamond.
