The biggest diamond in the known universe is a very gigantic gem located in outer space next to Planet Bling. In Take Me To Your Grumpy, Hildy wants the gem badly she and Grim tried at least four times to bring it down to Earth using spells. After all of their fails, she finally gets the diamond, but its size squished the Glooms and their home completely. Then four rainbows come out of it, and Doc couldn't be more estatic at the colorful sight.
