I think it's also fair to point out that there are varieties of quartz in practically every color we can percieve, which might make its CNR value somewhat weaker. Though the aforementioned varieties are the most commonly known (and among the most commonly found).

That said, "stork" doesn't entirely sit right with me in CNR terms. Storks aren't really known for their coloration like cardinals or blackbirds. Even White Storks actually have about as much black on their bodies... which I suppose could be a nod to Qrow and Raven? I dunno. Seems iffy to me.
