0.97 Ct. Red Zircon from Cambodia

This 0.97 carat, oval red zircon from Cambodia offered by The Natural Gemstone Company is cut to precise proportions, measuring 6.07 by 4.79 by 3.23 millimeters and executed in a mixed brilliant style. The crown displays a conventional brilliant facet array to maximize scintillation, while the pavilion employs modified step facets to control light return and enhance the stone's saturated red face-up color. The cutter has left a slightly shallow pavilion profile to preserve weight and to concentrate color intensity, producing an intense, evenly distributed red with lively flashes from the crown facets. Clarity has been evaluated as very slightly included at eye level, and the excellent polish produces clean facet junctions and crisp facet reflections, allowing the stone to exhibit controlled brilliance and a superior, gem-quality finish. Heat treatment has been applied, as is standard for color optimization in zircon, resulting in stable, saturated hue and improved transparency without detectable surface-reaching residues.

The unmistakable signature of this specimen lies in its internal inclusion suite and growth textures, which provide diagnostic, characterful features to a discerning observer. Under magnification the stone reveals a network of fine, oriented needle-like inclusions and microscopic angular crystal platelets aligned with the crystal growth direction, producing a subtle micro-facet effect that fragments light into small, faceted flashes within the body of the gem. Intermittent planar growth zoning occurs parallel to the girdle, producing faint banding that interacts with the mixed cut to generate alternating areas of deeper and lighter red when rotated, a pleochroic-like effect that aids identification and provenance assessment. These inclusions are intrinsic to natural zircon and, combined with the heat-induced stabilization of color, create a reproducible internal pattern that experienced buyers and lapidaries will recognize as indicative of Cambodian zircon material. For settings, this gem is particularly well suited to a low-profile bezel or four-prong mounting that protects the girdle while allowing the crown facets to reveal the stone's internal scintillation, and routine care with warm soapy water and a soft brush will maintain its polished surface and intense color.
