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.
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.
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.
