The photos form part of the description. Like all colored stones there is a color variation that occurs in different lighting conditions both inside but also outside, even the time of day can make the color of a stone appear a little different. We do our best to show colors as we see them. Color perception is highly individual and some people can perceive more colors than others, also colors can appear somewhat different on different screens and devices due to variations in screen hardware and device display settings. When you see this ring in person the play of color will look different outside, inside and in every lighting condition and in every angle! That is the beauty of course of this exceptionally rare natural gemstone. We do our very best to show every piece accurately in our listings and take photos in daylight equivalent lighting conditions.
