Some Information on Sapphires
Among sapphire buyers, it has pretty commonly known how different one stone can be another. Most of the sapphires sold in jewelry comprise lower quality gems. You have probably noted a pale blue color of some of the stones set in diamond & sapphire rings. Suffice to say, these are not the best of the lot, and that the color largely determines how good a sapphire really is.
