5.33 Ct. Yellow Zircon from Ceylon (Sri Lanka)

This 5.33 carat oval yellow zircon from Ceylon, Sri Lanka is precision cut to 10.19 x 7.89 x 5.95 mm, presenting a transparent body with intense color intensity and an excellent polish. The cutting style is faceted, executed in a mixed brilliant cut that combines a faceted brilliant crown with graded pavillion facets to maximize return of light and controlled dispersion. The oval outline is proportioned to balance table light return and scintillation, while the mixed brilliant faceting pattern produces tight, lively flashes across the face up view and step defined flashes along the girdle and lower facets. Clarity is graded eye clean evaluated at eye level, meaning the stone is free of inclusions visible without magnification, which enhances the perceived transparency and allows the yellow tone to read uniformly. No enhancement has been applied to this gemstone, preserving natural color chemistry and internal structure, and The Natural Gemstone Company has maintained the original polish quality and facet integrity during cutting to ensure optimal optical performance.

On the Mohs hardness scale zircon typically registers between six and seven and a half, which places this gem below corundum and diamond, and above many common jewelry minerals, and therefore durability considerations should guide setting and wear. For comparison, sapphire and ruby at nine and diamond at ten will resist abrasion and impact more effectively, therefore this zircon benefits from protective design choices when intended for everyday rings, such as bezel, half bezel, or protective prong settings that shield the girdle and lower crown facets. Despite moderate hardness, zircon offers excellent brilliance and strong dispersion for its class, but it is more susceptible to surface abrasion and chipping from hard knocks than corundum, so ultrasonic cleaning is not recommended for all stones and exposure to harsh chemical cleaners and sudden thermal shock should be avoided. For long term care, warm soapy water and a soft brush, periodic inspection of the mounting, and careful removal during heavy manual tasks will preserve facet edges and polish. This Ceylon yellow zircon, offered by The Natural Gemstone Company, is an exceptional specimen for collectors and jewelers seeking intense natural color, precision mixed brilliant cutting, and eye clean clarity, provided appropriate setting and care are used to protect its moderate hardness.
