The price listed is for one ounce of glass stones. These are black flat back glass stones that range in sizes from about 8mm by 6mm to about 22mm by 18mm. The shapes included are ovals, navettes, squares, triangles, and square octagons, which most are represented in the picture above. Most of the oval, square octagon, and navette stones have a recess for a 15pp (7ss, 2.2mm) to 17pp (8ss, 2.4mm) point back stones. Some of these already have stones in them, but most are dirty and should be replaced. There are both faceted and smooth stones included in this mix. In a sample one ounce pulled, there were 50 stones, however we cannot guarantee the number of pieces, only the weight.
