Comment: Huge color changer from Sri Lanka, cornflower violet blue in daylight and lavender purple at night. Some inclusions are visible to the unaided eye in some light and some angle but we couldn't get ourselves to call it ?moderately' included. Good crystal, never dark and the transition from day to night color is rather abrupt, less mixing of color in-between. We usually try to provide one photo with both color in mixed light but this stone switches remarkably fast.
