Price listed is for 1 ppm (about 22) stones. These are natural Marcasite stones measuring approximately 11pp (5ss or 1.7 to 1.8mm). We use a 6.5mm flat rimmed setting to measure out stones that are 11pp and smaller. Therefore, the number of stones received will not be exact. The picture shows the bottom of the stone but these have faceted tops and flat backs.
