Why do people keep making theories that certain gems are diamonds? It's crazy. Rose Quartz, Lapis Lazuli, Lighthouse gem,

THEY ARE NOT DIAMONDS! We've seen Blue Diamond, so we can stop saying Lapis and the Lighthouse gem are Blue Diamond.

Rose Quartz is a QUARTZ! NOT A DIAMOND! Her gem is not diamond shaped. Gems can't change the shape of their gem. Diamonds are three times the size of a pearl. Rose fits Peridot's description of a Quartz.
