These Cool Jewels ice cubes will make you feel like an international jewel thief every time you make a drink! Just fill this 4-1/4" x 7-5/8" food-grade flexi ice tray with water or any kind of juice and freeze. Then pop out the three-dimensional Cool Jewels and bling out your beverage! Just remember, unlike actual gems, these will melt and have very little value on the black market.
