A natural 1.62 carat blue sapphire in a round cut, from Sri Lanka (Ceylon), heat treated. Round-cut Ceylon blue sapphire at this weight combines the most popular shape with the most recognized origin — the round brilliant cut maximizes light return and produces the highest sparkle of any sapphire shape, and Ceylon blue is the benchmark color profile for the variety. At 1.62 carats, this sits solidly in the center stone range for engagement rings and pendants.
Why Choose this 1.62 ct Round Ceylon Blue Sapphire?
Round brilliant is the format that extracts the most brilliance from any colored stone, and Ceylon blue is the origin that produces the most consistently vivid blue at the commercial level. Together, they represent the combination most buyers default to when specifying a blue sapphire engagement ring — and for good reason. At 1.62 carats, this stone has enough face-up surface to display the blue clearly at wearing distance in any setting.
