A tiny little cast iron lantern w/ a clearie in the center for this "Sundays Best" I've had it for a long time & have no idea where it came from ?? Maybe a Christmas ornament I have no idea
So named Vitro"Windex cat" has a blue base like that, usually w/ white or light colored ribbons, "Killer score BTW"

Yes Akro, Popeye corkscrew :: It has a clear transparent base I can see the wispy white strands running through the clear base in this pic, there's a lot of white in this one but still has the transparent clear as a base.
Hmm ?? Here's one of my opals for comparison. Your second one has the right colors but the base looks funky for an opal !! MIght just be the lighting ??
