As many other gemstones, quality of a sapphire depends on its color, purity of its hue, depth of tone, and color saturation. Best sapphires contain slight traces of other colors, not on too dark or too light color extremes, and show lot of saturation.

Many favor color over other qualities of a sapphire. Most sapphires available in the market are treated to enhance its color. One popular method of treating sapphire stones is heat treatment to enhance its color. However, appraisal of a stone is still based on its color.
