Thank you for your replies, Spn.  I'm new to this, but I really like them.  I will search today and try to buy a copy of Elizabeth Kempski's book.

Thank you.  Yes, perhaps the cobalt blue one is Vacor.  The texture is oily and the surface is pitted orange peel.

Were light blue-green, 3 and 6-vein cat's eyes ever made anywhere other than in Japan ?

I was told these are old, and as some are light blue, I assume these are 60s or 70s Japanese.  The top left marble is a hybrid 28mm in diameter, the two horseshoe? pieces are cool, the yellow one having a large air bubble in the center. The one white 'banana' in light blue-green is also interesting.  The dark cobalt blue marble also seems unusual.  Thank you for any insight into these marbles.
