WHY WE LOVE THIS GEMSTONE
VIVID AND SATURATED
Sapphire’s blue can be vivid and saturated, like it’s lit from within.
It’s so durable, synthetic sapphire is used for the windows of supermarket scanners and spacecraft.
Sapphire often contains delicate intersecting needles of rutile that gemologists call silk.
Each color of sapphire has its own quality variations.
Sapphires come in a variety of colors. Preferred sapphires have strong to vivid color saturation, regardless of hue.
Blue sapphires typically have some inclusions, but they generally have better clarity than rubies.
Sapphire is often cut with a brilliant pattern on the crown and a step cut pattern on the pavilion.
Blue sapphires range in size, and large blue sapphires are more readily available than large rubies.
