blue sapphire

Blue sapphire can be said to be the representative of blue gemstones.
Sapphires come in a wide variety of colors and come in many shades, but when they are simply referred to as "sapphires", they refer to blue sapphires.
It is a jewel that has been loved by the British royal family, including the engagement ring of the late Princess Diana.
The most valuable colors are cornflower blue and royal blue.
Sapphire is the birthstone for September.
