Toothpaste

Put a little toothpaste on an old toothbrush and use it to make your diamond ring sparkle instead of your teeth. Clean off the residue with a damp cloth.
Here are some more handy uses for toothpaste that have nothing to do with your teeth.
Vinegar

Is vinegar good for cleaning jewellery? Yes! Here’s how to clean jewellery with it: soak your pure silver bracelets, rings, and other jewellery in a mixture of 1/2 cup white vinegar and 2 tablespoons baking soda for two to three hours. Rinse them under cold water and dry thoroughly with a soft cloth.
Vodka

In a pinch, a few drops of vodka will clean any kind of glass or jewellery with crystalline gemstones. So although people might give you strange looks, you could dip a napkin into your vodka on the rocks to wipe away the grime on your eyeglasses or dunk your diamond ring for a few minutes to get it sparkling again. But don’t try this with contact lenses! Also, avoid getting alcohol on any gemstone that’s not a crystal. Only diamonds, emeralds and the like will benefit from a vodka bath.
