Agate Marbles. 4 Pieces 3/4 to 7/8 Inch Diameter. Mostly Banded. Mix Colors. Natural Gemstones. Not treated or enhanced in any way. Vintage. I show 5 photos of same box of marbles mixing them well to give idea of what is available. But I will send 4 marbles, not the whole box. I have lots of marbles and I don't want to show separate ad for each lot of 4. Hand made. Shaped with grinding wheel.
