How do you identify a doctored image on jewelry Gemstone sapphire selling website?

There may be hundreds of online jewelry, color stone e-retailers.

While buying sapphires, ruby or color stones the "color tone" is of principal importance. It is the primary criterion to valuate a color stone. For example deep blue natural sapphire may cost 300% more than light blue sapphire. A stone image can be easily manipulated for color, hue and depth.

Recently I read a discussion on how a New York based Natural Sapphire company manipulated imagines to enhance the cost of the stones. To read that discussion yourself, see the page link, further down this page, in Sources and Related Links.
