Nice stuff!
Here are some swirls I have. No super heavy hitters but a nice group none-the-less. There might be an alley or two in here and the yellow looking one on the right might be an Akro, hard to tell.
Here are some like the fractured one you posted Steph. From what I hear, they are pretty rare and I think I was told they are named "royal purple" and only dug...if I remember right.
Some nice ones added here recently... love that last one you posted Scott!
Here's on I got recently from a friend. It's the only old marble I have from any maker with both aventurine AND metallic.
I was unaware of patch types from this company. I need to learn more about these, as I'm sure they end up mixed in with other makers in many collections (mine included I imagine). Any pictures of these would be greatly appreciated!
I've got some of those modern MKs with the blue like that too. I think yours might be pelt though Scott.
Here are mine, and some other more modern MKs, and those weird pelty looking ones last.
Good to know, I was a little worried when I bought it that it might be an irradiated amber snake since I haven't run across this color in Akro before. Nice examples Paul!
