Here are some things Steven Universe got wrong (Geology wise)
Gems are objects and is confirmed that they do not have genders but Rebecca also confirmed that they are lesbian. How can objects show sexual relations with each other
Bismuth is a metal not a gem
Diamonds and Quartzs are in different crystal families and are not the same
There are other colours of Sapphires then ablue
Rubies are the most precious gems so why aren’t they in charge
Diamonds are primarily clear but natural coloured diamonds are usually shades of brown or tan
