Very pretty gray freshwater pearls, the shape is good for button pearls, and the surface is unblemished. The size exactly what I wanted, about 8.5 mm. Where the post is mounted to the pearl seems a little small for the size of the pearl, but I'm being careful when I put them on and take them off. The backing is fine. I got them at a great price so I'm satisfied. I got them in pink also, just as nice.
