In search of moqui balls

Hi, everyone, my grandson, age 10, often opens my rock case to look at my moqui ball. We searched for one for him at the rock and gem show, but came up empty. One vendor gave me his card and told me to check with him later. Unfortunately, I went to call him this morning only to find that I had been holding on to the wrong card. Can one of you help me out? Hoping for a Christmas present. :)
