This is Green Diamond. He is a small Diamond like Pink. But is a guy. His story is him Pink and Black, Black is the third small male Diamond who exists his powers are destruction, Greens powers are nature, he can make planets, life, ect. He made Earth just for Pink. Him and Pink were best friends. Wile him and Black fell in love. But the bigger Diamonds didn't like that. (Mostly white) and banished them to two different planets. That's why the bigger Diamonds didn't want Pink to go to Earth.
Also they boys had spinels also. But their pearls got shattered.
Ehh I drew this at like 2am yesterday so yeah. No eyes for him
