[ik I already have a watermelon tourmaline gemsona, but this is not her, this is a fusion who happens to be the same gem type] also yes the 2 who make up the fusion ARE the same gem type, just different colors, but that doesn't mean she can't have 4 arms. Them being different color Tourmalines adds to why it doesn't just work like a Ruby fusion for example. Watermelon Tourmaline, a fusion of Green and Pink Tourmaline. My projects about GT and PT already have all the information I'm giving you guys about them so far so there's not much else to write about Watermelon Tourmaline.
