The term Royal Blue is reserved for the most illustrious sapphires. This color term can only be applied to sapphires that exhibit fine qualities and have not undergone any modification of color or clarity. Sapphires that exhibit a deeply saturated blue color, possibly complemented by a minute trace of purple and balanced by a vivid brightness are recognized as Royal Blue by the gemological laboratories.
