GIA Certified 3.12ct Unheated Burma Red Spinel Diamond Platinum Ring

A GIA-certified 3.12 carat natural unheated red spinel from Burma (Myanmar), set in a platinum and yellow gold two-tone ring with a rectangular cushion pavé diamond halo, scalloped corner bracket detailing, and a slim pavé-set shank. GIA states "No Indications of Heating." Red spinel from Burma is among the rarest and most historically significant gemstones in the world — historically mistaken for ruby, Burmese red spinel appears in royal jewelry collections worldwide. At 3.12 carats unheated with GIA Burma origin confirmation, this is a genuine collector's stone; examples over 3 carats at this quality level are exceptional. The stone displays a deep, vivid red with strong saturation. As with all natural spinel, inclusions may be present; no clarity grade is issued on GIA Spinel Origin Reports. Buyers are encouraged to review all photos carefully and request additional images before purchasing.
