Choose from a rainbow of sparkling chaton crystals in assorted sizes. These leaded-glass crystal stones are foil backed for maximum bling. Their pointed backs make them perfect for embedding into crystal clay and other jewelry clays, or repairing vintage rhinestone jewelry. Sold per 5 grams, assortments may include PP12 (1.9mm), PP16 (2.3mm), PP21 (2.8mm), PP24 (3.2mm) and SS18 (4.2mm) sizes of crystal chatons. The color of the foil backing, and the crystal colors themselves, may vary a bit from batch to batch, and size to size. The first 12 items below are in birthstone order from January through December, and pretty purple Tanzanite is an alternate for Blue Zircon, the more common December birthstone. The mega birthstone assortment offers 12 popular colors all at once! p.s. Assortment #07-001-00 is actually an accidental assortment. It was supposed to be the birthstone assortment (with each color bagged separately), but we had a miscommunication and we mixed a bunch of random colors together instead. It's still lovely and sparkly! But it has jet and fuchsia in it, and is missing some of the birthstone colors. For design ideas, check out our free #resin and jewelry clay projects.
