Only a few varieties shown here. The number of varieties are almost as numerous as there are pieces made. These are CRUDE. I'm talking handprinted with Sharpie markers (won't fade if wet) and none are perfect. Here are the oddities: several colors of markers are used, mostly black. Colors of the Dyed Mother of Pearl Shell run from Natural to Blue-Black and almost any other shade you might imagine. The darkest colors that are too dark for printing are etched and etched poorly, I might add. Sizes range from 20 millimeters to 70 millimeters. Some of the small sizes are curled to look like shallow bowls or saucers. About 200 of the smallest were made and likely not more than 50 of the 70 millimeter. Middle sizes 30-50 millimeters are the most common. I have a bunch of these. See the web store.
