White zircon is the often-overlooked natural gemstone alternative to diamond - genuine mineral zircon in colorless form has a refractive index actually higher than diamond, meaning it disperses light with more fire and brilliance than the stone it is frequently compared to, but at a fraction of the price. This Wrapped in Gold solitaire pendant features natural white zircon in an 18K yellow gold over sterling silver setting at 0.50" long by 0.51" wide on an 18" Singapore chain with lobster claw clasp and 2" extender. The oval 7x5mm white zircon presents maximum colorless sparkle across its face - the higher dispersion makes each facet appear more brilliant than a comparable CZ. A natural gemstone for the wearer who wants diamond-adjacent sparkle from a real mineral rather than a manufactured simulant. December's birthstone. For the December birthday, or for any wearer who wants the clear, brilliant sparkle of a colorless stone with the authenticity of natural mineral origin. Zircon has been worn as jewelry for centuries and its optical properties remain unmatched by any synthetic alternative.
