Comment: Clean but slightly windowed color-shift sapphire. From a pretty nice Kashmir blue at day to a purplish violet at night. Under 1k/carat. With nearly 7x8mm the window pays itself off in extra big face. We usually avoid windows but the daytime color was too tempting in that size though the camera does not really transfer it. Bargain. We describe this grade of change as "color shifting" while most websites/gem-labs will define this simply as a color changer (so does the certificate). A color changer needs a jump across the color wheel (e.g. red to green) not only a shift from blue into violet.

Ask a question.
