The Standard For Blue Sapphires. For a sapphire is to be called âblue,â its secondary colors (e.g. green or purple) must not account for more than 15% of its color. Sapphires that have secondary colors in greater quantity would be classified as greenish blue, purplish blue, violet, etc. These are known as âuniqueâ or âfancy coloredâ sapphires.
Large commercial-quality blue sapphires are more common than large fine-quality ones. As a result, size makes more of a difference in the price of fine-quality sapphire. A fine-quality 5.00 carat blue sapphire sells for approximately five times more per carat than the same-quality 1.00 carat stone. A commercial-quality 5.00 carat stone sells for only about twice as much per carat as a 1.00 carat blue sapphire of the same quality. These examples are not meant to be exact pricing guidelines, but to illustrate how much the per-carat price can go up as the size and the quality rise.
