1.59 Ct. Yellow Zircon from Ceylon (Sri Lanka)

This listing describes a transparent yellow zircon, oval shape, weighing 1.59 carat, with dimensions 7.44 by 5.62 by 4.00 mm. The cutting style is faceted, executed as a mixed brilliant cut to balance table brilliance with pavilion dispersion. The color is classified as intense, and the polish is rated excellent, resulting in lively face up appearance and refined facet delineation. The clarity grade is eye clean as evaluated at eye level, and the stone is presented without any enhancement. The material origin is Ceylon Sri Lanka, and The Natural Gemstone Company supplies this natural, untreated specimen with full disclosure of its provenance and characteristics.

Natural internal features in this zircon serve as unique identifiers and contribute to the gem character rather than detract from it. Although the stone is eye clean, microscopic examination reveals internal features that are typical for natural zircon, including minute mineral crystals, fine growth zoning, and small healed fracture contours. These features act like a fingerprint for the stone, providing evidence of natural formation conditions and individual history. Inclusions influence the way light interacts with the crystal lattice, sometimes producing subtle internal reflections and localized color zoning that enhance perceived depth and complexity. Because the cutting was oriented to maximize color and brilliance, the internal features remain unobtrusive to unaided viewing, while offering useful markers for identification, documentation, and long term tracking for collectors and appraisers.

The gem displays notable optical performance, characterized by strong luster and pronounced dispersion relative to many other gem species, which contributes to a lively play of light when set and viewed under varied lighting. The mixed brilliant cut delivers a balance of scintillation and flash, making the piece suitable for a classic ring, pendant, or custom setting where the oval proportions will complement many design lines. Practical care considerations reflect the material properties of zircon, which has moderate hardness and can be sensitive to prolonged heat exposure, so avoid thermal shocks and aggressive steam or heat cleaning processes. Routine maintenance is best performed with warm soapy water and a soft brush, and settings that offer protection such as a bezel or well positioned prongs will help preserve the stone during daily wear. This natural, intense yellow zircon, supplied by The Natural Gemstone Company, offers documented origin, uncompromised clarity at face up inspection, and a polished finish that highlights its natural optical charm and individual internal structure.
