types of natural sapphires
A subclass of blue sapphires is cornflower blue sapphire, which represents an intense velvety blue color. Most of the blue sapphires have silk or inclusions present in natural form and these actually enhance the beauty as well as the value of the stones.
One of the most desirable colors in sapphire is pink. Pink sapphires occur naturally in different hues of pink, varying from pale pink color to a deep magenta color, which is attributed to the presence of trace impurities of chromium in the gemstones.
