Price listed is for each ounce of stones. This is a mixed lot with a very wide variety of opaque acrylic flat back stones. Included in the mix are rounds, ovals, squares, navettes, hearts, baguettes, and pears. Sizes range from around 4.5mm up to about 30mm. Colors include black, pink, green, red, yellow, green, gold, glitter, turquoise, and more. Most are opaque, though there may be a few transparents and/or foil backs mixed in. Most have rounded cab tops, though a few have high domed bullet nosed tops, faceted table tops, or rauten rose tops. There may also be a few glass stones in the mix as well. The sample half-ounce had about 50 pieces in it. We cannot guarantee the exact number of pieces you will receive, only the weight. It's the luck of the draw!
