Oh, and as for the snake: Don't let the head stamp fool you, this is a Wild Type ('Normal') from a proof cross, no currently acknowledged morph genes present.
Whatever is going on with him/her is pretty cool. It sounds like you have at least proved it to be heritable if this is the offspring. Reminds me a bit or orange dream or JKR's peach project.
Also, really cool info about quartz and topaz. I didn't know any of that.
