Cubic zirconia are also known to exhibit a greater spectrum of color than real diamonds when light is focused on the stone. 11. Click to show or hide the answer! Cubic zirconia has an RI 2.15 2.18, which is higher than zircon. Cubic zirconia. Because of its high hardness, it is generally considered brittle . Under shortwave UV cubic zirconia typically fluoresces a yellow, greenish yellow or "beige". Under longwave UV the effect is greatly diminished, with a whitish glow sometimes being seen. Colored stones may show a strong, complex rare earth absorption spectrum . For both cases, the light enters air, so n 2 = 1.00.
