I love this yellow sapphire. Of course, unheated, untreated & completely natural, as mother nature created millions of years ago underground. It hails from the gem fields of Kuruvita, cut & polished in Ratnapura, Sri Lanka—a very elegantly shaped, unheated yellow sapphire with a light "sunshine" yellow color. Ideal for a person with long & slander fingers, this sapphire is sure to please & set exquisite.
