We have seen all base Beryl, Emerald, and Amethyst cards!! 
And only a few more for the Ruby. (pretty sure we have seen #41, but I didn't have a picture of it)

I've definitely seen a few Onyx that aren't marked. Dude on reddit just completed the red pill rainbow. A couple others posted on there recently.
Also, just tonight someone was trying to trade a Ruby MR1
Edit: I traded a #9 Bitcoin Crunch Sapphire to someone who pulled the Onyx of the same.
