This sapphire exhibits a colour change depending on the lighting conditions, likely shifting from bluish green to blue. Although the stone does display this characteristic, it is not mentioned in the laboratory report, as most gemmological labs only note colour change when the stone shifts between warm and cool colour tones (e.g., red to blue).
