My obsession with clay marbles led me to becoming obsessed with china marbles as well, which are the same consistency as the clay marbles, but are distinguished by their white color and decorations painted on them, frequently in patterns of fine lines like these, sometimes running in opposite directions and crossing, and sometimes with painted circles, bulls eyes, or flowers. While there are some much fancier, and many were fired to produce a shiny white glaze, I like the relative simplicity of these old German ones, and find them really lovely.
China marbles are highly collectible, with fancy ones fetching hundreds of dollars. I'm selling them individually but suggest getting at least a few together. Please indicate on your order if you have a preference for blue or purple; if you feel very particular about which specific ones you want, I will try to accomodate. (Otherwise I will choose the best among them, and include a second lesser one—which I’ve featured in the last couple photos—as a free bonus with each marble purchased while supplies last.) The marbles measure approximately 5/8" in diameter, with a few a hair larger.
