3 unused dichroic glass pendants for your own jewlery creations. would look great on a cord or fancy beaded necklace or chain. Dichroic Glass: This type of glass has a high-tech coating that makes it change color depending on the lighting and the angle from which it is viewed.  The pendants are handmade, often by artists who cut, layer, and arrange the glass pieces before firing them in a kiln at high temperatures (around 1400°F) to create a single, solid piece. Bails: The metal loops attached to the top of the pendants are called bails, which allow them to be hung on a chain or cord. The ones pictured appear to be a type of "pinch bail" or "fold-over bail" which are glued to the back of the undrilled glass. They are strong and will keep your pendant hanging right where you want it!
