An imperial topaz weighing a monumental 15.61 carats and displaying a highly prized reddish-orange hue is the star of this remarkable ring. Imperial topaz is the rarest of all topaz varieties, and this stone is certified by the American Gemological Laboratories (AGL) as being natural imperial topaz, meaning it has undergone no heat treatment to achieve its incredible color. The oval shape of the stone elegantly elongates the finger it sits on, while the modified brilliant cut amplifies the spectacular hue. Surrounded by 0.58 carat of diamonds and set in platinum, this ring is the very best of its kind. Download the CertificationClick here to view a video of this item.
