Notes: This is one of the most interesting CC sapphires I have cut. I will try my best to describe and document the colors. It shifts from a slightly greenish blue in 6500-5500k, incandescent appears to have a greyish violet color and in natural light bluish green. Umba Valley is known for its color shifting material especially the sapphires. However this one is strange bird for sure. Has some slight sugar that is extremely difficult to see by the unaided eye and small inclusions near where a prong would be set to hide it.
