Diamonds may be a girl's best friend (could that be even before her mobile, DS Lite and Hello Kitty paraphernalia?) but you certainly don't have to be rich to get these sparkling jewels. Pour water into this ice tray, pop it in the freezer and hey presto! ice cube jewels. To be fair they won't last as long as a trip to Tiffany's but it won't damage your bank balance either. And you'll get a cool drink. I was going to try and squeeze in a joke about showing off your jewels but alas, I could not lower myself that far. £4.95 at Firebox.
