Cerulean Diamond (Kaimamaster317)

Cerulean Diamond is a Homeworld Gem and was a member of The Great Diamond Authority that previously ruled over the Gem race. He appears in a flashback. He was formerly a member of The Great Diamond Authority until being banished for losing one of his followers, Red Diamond. It is revealed in ancient text that he is defective, due to him being a he, and that he is a Cerulean Diamond, which is not a type of diamond, but a deformity of Blue Diamond.
