This listing is for five 25x18mm rectangle octagon Light Sapphire Blue double faceted glass jewels.
Double faceted means not only are they thicker than regular faceted glass jewels but they are also faceted on both sides. They are sometimes referred to as cushion jewels because they have a bottom flat center. They're also especially nice to work into your leaded windows.
