Stunning natural amethyst chunk pendant with gold plated copper wire setting and gold plated chain. These are crazy cool! These vary quite a lot in shape and size; from 25mm long to 50mm long (including bail). Sold per pendant. Irregular Amethyst Stone Pendant. This pendant is made of natural amethyst, so it is hard to keep them in a fixed shape and colour. The item you receive will be a little different with the picture.
