A rare Burma sapphire weighing approximately 3.20 carats displays its vivid, royal blue hue in this ring. The cushion-cut gem is certified by both the GemResearch SwissLab and C. Dunaigre as Burmese in origin and untreated, meaning it has undergone no heat enhancement to achieve its spectacular hue. The sapphire is set in platinum amid white diamonds weighing approximately 0.33 carat.
