The size of these amethyst beads is 15 x 20mm. 2A Grade quality beads here folks. These are flat oval amethyst beads with a slight twist. There are no facets here but the twist and natural shape of these amethyst beads just takes my breath away. These amethyst beads are polished to perfection. These beads are a beautiful lighter purple amethyst color. There are some natural inclusions that add to the natural beauty of these gemstone beads. Super pretty and very limited!!!!
