@Kronshi I do get what you're saying, but I also feel that given the difficulty presented with Mars' gem, some corners have to be cut. Ask
@Loony for ideas on gem names, though, as they've got a lot of knowledge in the subject and might be able to help.
Blizz suggested Purple Agate for the Mars/Azurite fusion, by the way. Or was it something else? Can't remember?
