blue sapphire
Cerulean precious stone
Blue sapphire is a precious gemstone—a variety of the mineral corundum colored by trace amounts of iron and titanium.
The modifier blue distinguishes it from sapphires of other colors (pink, yellow, orange), though sapphire without a qualifier typically means the blue variety.
Prized for jewelry, the finest specimens show a rich, velvety blue: a ring set with a Kashmir blue sapphire.
