While I think the Green Triangle, has more to do with with Peridot's ship since Peridot is not loyal to a Green Diamond and is instead loyal to Yellow Diamond. Fusion of the Diamonds can't be ruled out though but if the diamonds could fuse to form pink diamond it raises the question why they did not use that ability to crush Rose's Rebellion.

Also since it seems people don't believe there is a Pink Star diamond. http://www.discovery.com/tv-shows/game-of-stones/pink-star-diamond/.

The site also gives evidence to support rarity=power theory since it features Alexandrite  (the fusion gem of the 3 crystal gems) as one of the top ten rarest gems.
