4.65 Ct. Brownish Yellow Zircon from Ceylon (Sri Lanka)

This transparent round brownish yellow zircon weighs 4.65 carats, and measures 8.66 by 8.23 by 6.70 mm, cut in a precise faceted form with a mixed brilliant cut. The cutting schema combines a brilliant crown with a faceted pavilion to maximize return of light through the table, and the excellent polish on all facet junctions produces crisp facet reflections and lively scintillation. At a measured depth of 6.70 mm against an average girdle diameter of 8.445 mm the depth to diameter ratio is approximately 79 percent, a proportion that balances face up spread with internal light performance for a visually impactful presence in open settings. Clarity is graded very slightly included at eye level, and the inclusions are minor and well positioned so they do not interrupt the overall light return or the gem appearance when set.

Color is described as a brownish yellow with light intensity, and the gem exhibits a warm, honey like tone that shifts subtly under different light sources. Zircon s inherent high refractive index and dispersion accentuate this warm hue, creating fire and spectral flashes that animate the stone with each movement. The mixed brilliant faceting enhances both broad flashes from the crown and finer scintillation from the pavilion, so the color reads vividly yet with complexity rather than flatness. Because this stone has no enhancements and retains its natural state from origin Ceylon, Sri Lanka, the color is stable, and the excellent polish preserves crisp facet edges that allow the gem to project color and brilliance above the mounting.

For design integration this zircon will stand out in any jewelry setting, from a classic solitaire that emphasizes its round outline to a halo arrangement that amplifies perceived size and presence. In yellow or rose metals the brownish yellow tone gains warmth, while a white metal mounting offers a lively contrast that highlights dispersion. The Natural Gemstone Company presents this stone as an ethically sourced, untreated example of Ceylon zircon with technical attributes that appeal to discerning makers and collectors, and our recommendation is for a setting that allows light from both crown and pavilion to enter freely, so the gem s natural vibrancy performs to its fullest in the finished piece.
