This natural greenish purple sapphire is from Ceylon. With a weight of 0.66 ct and an oval shape, this gemstone has been heated to enhance its color. Its optical appearance may vary from bluish to greenish, depending on the angle of light. With good to very good cut, polish, and symmetry, this sapphire has a vitreous luster and is ideal for high-quality jewelry.
