Marbre ancien taille .728 - .736 soldes

I found this several years back in an abandoned shed with several others Im using deduction when I say its vintage being that the rest of the marbles with this one date back to the 1930s of course this one was different larger it has one spot that looks like damage but it may be from how it was made. It doesnt have a consistent size but not so much it can be seen by looking at it. There is some fluid-like movement going on in it reddish-looking streams. One feature I have only seen with this marble is the microscopic bubbles lined up in a row like tiny soldiers on a mission. Ive looked at this one for a great deal of time. The price I placed on it doesnt reflect my belief its HTF or one of the big names. Its appreciation of the item itself would gratefully trade for others but thats not an option on this platform so if you would like this collectible piece make an offer with the asking price in mind and we will do that.
