White zircon possesses an impressive refractive index, which contributes to its remarkable sparkle and fire. When properly faceted, it reflects light with remarkable brilliance, creating a scintillating effect that captures attention. Its high dispersion allows white zircon to disperse light into a spectrum of vibrant colors, resembling the fiery play of colors seen in diamonds.

The gemstone is often cut into various shapes, including round, oval, cushion, or emerald cuts, to maximize its brilliance and beauty. White zircon is highly valued for its durability, ranking at 6.5 to 7.5 on the Mohs scale of hardness, making it suitable for everyday wear.
