The pair may be in the Tiger Eye family ... but the last view makes me think maybe a little earlier than that.
For the standalone, that's big for even a Jabo. But that's my best guess for now. A Jabo Classic.
Vitro in post #1.
What size is the one in post #2? (If large it could be a Jabo Vitro. If standard size, then WV swirl companies are an option ... or it could still be a Jabo Vitro.)

What actually makes a Moonie change color when backlit?

M.F. Christensen? Or Christensen Agate?
I wouldn't be able to say anything other than they look "handgathered" .... and that one with the waves is pretty far out.
That's the rub. If it's 1930's, then Vitro Tri-Lite.
But I can't be sure it's that early, so I can't be sure of the company name. I can't think of anything else it could be though.
