A very crisp, unheated, blue Ceylon sapphire from the gem fields of Ratnapura, Sri Lanka. I love this cut; it is so well done and proportioned. There is no "window," and the stone bursts in a scintillating light dance. It is natural and unheated; therefore, it is an excellent investment for the future. These unheated sapphires will always appreciate value and do not overthink at this price.
