A Sri Lankan sapphire of 3.16 carats, reported by AGA with Ceylon origin and graded as Vivid Blue, AGA type "Royal Blue" — the classification reserved for the deepest and most saturated blues in fine sapphire. The color is rich and intense, holding its strength across the whole stone, with flashes of electric blue breaking through as it moves. The stone is clean and transparent, and its oval cut carries the weight well at over three carats. Heated, the standard and universally accepted treatment for blue sapphire.
