This is my favorite micro mosaic spaniel of all time. The large 2 & 3/8 by 1 & 7/8 inch brooch is made of unmarked tested 14 karat gold and incredibly fine glass tesserae. Notice the dogs rear toe nails. The surface is polished mirror-smooth. There is a very light scratch but look closely at it. It can be polished out practically by hand. Still, I do understand that some folks want PERFECT so I want to call attention to it. It was very hard to get it to show in scans. :) What I love about this sporting scene is the movement of the subjects--not static like most micro mosaic dogs reclining on grass or puffy pillows. I actually bought this pup at Ruby Lane several years ago--only the best here!
