Nothing has the ability to cheer me up and bring me out from the darkest recess of my gloomy thoughts more than a novelty ice cube. Happy days, now that the Cool Jewels are out. Cool Jewels are a perfect way to cool your drink from the blazing summer sun while adding a bit of glamour to your life; each "cube" is actually the shape of a giant gemstone. Guests might be slightly stunned by your almost expensive looking ice gems. The tray makes six different shaped jewels at a time.

Get them quick before the summer is over, for £4.95 or just under $10 from Firebox.
