This gem is a fine example of why the sapphires from Ceylon are considered among the best blue sapphires in the world. Ideally sized and nicely cut in the classic square cushion, this beautiful Ceylon cornflower blue sapphire would look amazing set in a fabulous ring and gracing your fingers. At night time you should see these blue sapphires sparkle – they LOVE the night lights and look simply exquisite. I highly recommend this elegant blue sapphire to you.
