Make your silver rings sparkle again!!

I love silver rings and wear about 4 of them complete with their turquoise, amethyst and coral stones. I have found a way to clean them that doesnt tarnish the stones and it is really simple and effective. Line a dish with some aluminium foil sprinkle about 6 tablespoons of bicarbonate of soda and put some boiling water over it. Add your rings and leave for a couple of hours or overnight. Clean them with an old toothbrush and they will look like new again with no black marks!!
