Optically this stone performs strongly across lighting conditions because of its refractive properties and its vivid saturation, under natural daylight, especially north light or indirect daylight, the sapphire will display its truest blue, bright and clean with a rich mid to deep tone, in strong direct sunlight you will note increased contrast between the brilliant facet flashes and the darker body color, this produces a lively play of bright flashes against a velvety blue background, under warm incandescent or candlelight the gem will appear slightly warmer and more royal in tone, with some of the blue leaning toward a deep, rich navy, under modern cool white LEDs or fluorescent lighting the vividness will tend to pop, showing sharp facet reflections and lively scintillation, the mixed brilliant cut aids in preserving color saturation while still returning significant light to the eye, the stone measures about 62 percent in depth relative to diameter which is within the range that helps maintain color without sacrificing brilliance, excellent polish further enhances facet contrast so highlights appear clean and well defined in both still and moving light, when set beneath a table or in bezel settings the stone will retain its vivid core color due to good transparency, while open prong settings will maximize sparkle and the sense of depth.
