I agree--a very nice marble Fire regardless.
Woodies just look—well like wood---with wood like colors and structure. I will post a few below of what I think may be “Woodies”---I love the wood looking aspect of these—some of my very first and very favorite Pelts.
Marble—On!!
Slag vs swirl, always a good question.
These are both WestVirginiaSwirls in my opinion. Not Akro.
Vaseline will glow brightly under UV light, hard to tell with yours, it may glow.
Marble—On!!

Marble--On!!
