Price listed is for 12 stones. These are acrylic triangle shaped rhinestones that measure about 12.5mm. From top to bottom they measure about 11mm. They are dark Siam ruby, and have faceted tops and flat silver backs. Most have a little rough spot where they were pulled from the mold, but the spot can be filed down to make it less noticeable. Some may have visible surface scratches and/or may have damage to the silver on the back.
