Quote from Alvoria
From my learnings.
Actually, my mom has an interest in gemology; and like most nerds, enjoys droning on about it endlessly. (I'm the same way about certain things. Guess it runs in the family) This is also how I know that diamonds can be virtually any color. Literally, there's no "wrong" color for diamonds to be... including the classic Minecraft blue.
I see. Well, I guess there's nothing wrong with this idea. But it has been done SO many times before.
