Is this a corkscrew?

I lost my caliper so can’t get a measurement. It’s shooter size.

It's a cool looking marble, whatever it is. And while I certainly haven't seen them all, it doesn't look like any Akro Corkscrew I've seen before. Looks a bit more like some sort of a hand-gathered marble - reminds me a bit of a Japanese Yasuda, but I haven't seen one of those like this either. It'll be interesting to see what others say. Maybe a contemporary?

Agree its not Akro, and I also get Japanese flavors from it.

[Ric]

Maybe it is a Japanese transitional and it just has an exceptionally clean "pontil" - they are usually pretty rough.  It's a very nice marble, regardless.

[Melissa]

I like it a lot.

Not a corkscrew and I agree transitional hand gathered.  I'll echo the cut off/pontil looks very clean compared to most Japanese.  The glass quality, pattern, and even the color are nicer than what you'd normally associate with Japanese.  Nice example.

Thank you!
