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 brownish green in 6500-5500k, incandescent appears to have a greyish violet color and in natural light it is a bluish green. At times the stone can appear grey or brown. 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.
