Our line of S-grade acrylic chatons are value priced and offer a light weight alternative to machine-cut crystal glass stones. These plastic stones come in a variety of transparent jewel colors, with a silver foil backing. Be careful to use the correct glue when setting these stones. Glues which work well with glass stones may eat through or compromise the foil on plastic stones. Great for crafts, jewelry and more! Lead-Free. Made in Korea.
