I know these are a little cheesy, and totally border on downright tacky, but I just couldn't resist! I think with the right approach these jewel-shaped ice cubes could be really beautiful and fun, and add that little extra something a summer gathering might be missing. Who wouldn't want bowls of glittering jewels sitting around like ice sculpture at a party? You can even add food coloring and have jewel tones to match your decor or beverages. The plastic ice cube tray measures 4 1/4" x 7 5/8" x 1" and makes 6 gemstone shaped ice cubes at a time. $5.95.
