For your consideration is this foursome of transparent swirl marbles. Not positive on any of the makers, but I think there is a Ravenswood or two, and maybe a Champion and/or Alley, possibly a Heaton, too. From the left, darker green at .58" and Mint-. 
It has a scratch. Next is the slightly amber transparent at .62", the largest of the group. It has a tiny bubble pop. Next is the opalescent, translucent, light lavender marble at .60". It is Minty, and it might be Ravenswood. It's a Dandy! Lastly, is the lighter green, mirky transparent, at .61" and Mint-. It has a couple sparkles, or tiny bubble pops. Just a beautiful assortment of pretties. Look over my photos, to get an appreciation of their charms. Ask any questions you may have. Shipping will cost $5.00 for USPS Ground Advantage. Thanks for stopping by.
