Sometimes jewelry cleaner is nowhere to be found. When I need to clean my silver, gold, diamonds (no delicate gems!) I mix a bit of windex and water and let them soak for about 10 minutes. (too long could turn them blue, which is reversible but also avoidable) Also, I like to use those new spinning toothbrushes (you can pick them up in a drugstore for about $7, so get all the soap and gunk out of the rings...It makes them SPARKLE!!
