Comment: The experienced eye can detect this sapphire's pull into nightly color-change already in the pure daylight image. The violet-purple peeks-out behind the blue as a soft warm glow. I have tried to show the step-by-step change under 'more images.' The final tungsten-only image blurred in reflection but the CC is obvious. Complicating the view is a set of colorless bubbles occupying one quarter of the round. These bubbles take-on their own life under tungsten light, reflecting in white spots. Though the very center of the gem is open, I can't get myself to call this a window - it's too small. Like all CC it shows both hues at the same time in most light settings. Obviously this is a local hand-cut, not perfect but good enough to make our collection. Fresh report at cost. Visible in back-side image is more color, the solid cut and also the stripe of bubbles seen from the other side. Though the front images underline the bubbles, they are lens-only. While you can take time to discover the colorchange in all its details, this gem delivers a solid blue-sapphire-show as seen in handshot. In 6mm round ring sizes from 4 to 6 in prongs, or seven in bezel.
