Under my yellowish light this pastel blue, which stays blue, really drinks in the color and becomes a solid medium tone. I have to realize that this gemstone will not be as intense under daylight. (I also checked the back of its storage box for its tone level). The standard round brilliant appears to be eye clean and with fine crystal. It is nice to have a lighter tone level blue that is both stable and clean. It weighs 1.84 carats and flashed it way past security and is now a wanted droplet of color.
