I found this quite a few years ago. When I first picked it up I was thinking crockery - but no, it's stone (~ 1 1/4"). The colors are great. Some of them are similar to those found in variegated clay Jaspers (white, blue, green, pink), but there are also black, gray, brown and yellow tones (the dark brown in the upper right shot looks like a stain). Overall, it's pretty round, but there are quite a few "flat" spots on it (a wobbly roller). Does anyone have experience with these types or similar to show? It's quite a bit more colorful than the Blood Allies and other marble marbles I have seen. Any info or thoughts will be appreciated. Cheers!
