Can't really tell from the pics. In most cases the oxblood color will appear to be painted on the marble. Excluding bricks of course.
Glad I could be of some help.
thanks, Carowill
The rough marks are where they were cut off the cane and known as pontils. This type of German handmade marble is known as "Mist". Late 1800's to early 1900's.
thanks
This one may be your CAC. It appears to have a brighter green and very clear glass (compared to the others) with bright white glass stretched and swirled inside.
thanks
