This is Druzy: Gem Harlequin
A harlequin gemstone is one that's multiple colors. That's actually one synonym of the word harlequin lol

Druzy is a fusion of two unknown gems I still gotta make lol. Druzy didn't know how to unfuse when on Homeworld and was going to be broken, but she escaped by high jacking a Ruby scout ship and went to earth.
I'll save her backstory for another part because it's kinda mixed with Onyx's story.

I own all my characters don't steal plz
