1.24 Ct. Greenish Blue Zircon from Ceylon (Sri Lanka)

This transparent, Other certified, greenish blue zircon from Ceylon, presented by The Natural Gemstone Company, weighs 1.24 carats and is fashioned into a refined oval measuring 6.83 x 5.49 x 3.68 mm, faceted with a mixed brilliant cutting style. The stone displays a medium color intensity that balances depth and lightness, producing a greenish blue hue that is immediately pleasing and classically associated with Ceylon zircons. The cutting emphasizes both scintillation and dispersion, the mixed brilliant arrangement optimizing crown and pavilion facets to deliver lively return of light. The gem has been heat treated to enhance color stability and uniformity, and it has been evaluated at eye level as slightly included, a clarity grade that reflects natural internal features without compromising overall visual appeal. The polish is excellent, resulting in crisp facet junctions and sharp reflective planes that contribute to the gemstone s clarity of appearance.

The internal characteristics of this zircon give it an unmistakable signature, a set of natural inclusions and growth features that are consistent with Sri Lankan provenance and that provide both identification markers and aesthetic interest. Observed under magnification, the stone shows fine healed fissures and narrow feathering, structures that refract and diffuse light along subtle channels. These healed fissures often display iridescent flash when illuminated, creating delicate spectral highlights that trace the stone s internal geometry. Minute mineral crystals and tiny reflective platelets occur sporadically within the body of the gem, their presence producing pinpoint scintillation and localized sparkle. Growth zoning and faint planar features are visible in cross section, evidencing the crystal s formation environment and thermal history, and occasional small fluid inclusions can be found in isolated pockets, adding to the textural complexity of the interior. Together these elements form a diagnostic internal fingerprint, a combination of healed fissures, platelets, crystal inclusions and zoning that experienced gemologists associate with well formed Ceylon zircons.

The slightly included clarity grade, combined with the mixed brilliant cut and excellent polish, results in a stone whose inclusions enhance rather than detract from its character. Facet geometry interacts with internal reflections, translating minute internal elements into lively surface scintillation and subtle flashes of color due to dispersion, particularly around facet junctions and along the girdle. The medium color intensity allows these internal features to be observed with clarity at eye level, while still maintaining sufficient saturation to read as a cohesive greenish blue in various lighting conditions. Heat treatment has been applied in a controlled manner to intensify and stabilize the stone s color, a standard practice disclosed in the gem s documentation, and this treatment does not obscure the inclusions that constitute the gem s natural signature. The result is a balanced presentation, where cut, polish and internal character are in deliberate harmony.

For collectors, jewelers and connoisseurs seeking provenance and natural character, this 1.24 carat Ceylon zircon offers both measurable specifications and a distinct internal identity. Its dimensions and mixed brilliant cut make it well suited to a variety of settings, with recommendations for protective mounting if daily wear is anticipated, given the material properties of zircon and the desirability of preserving facet edges and surface polish. Documentation accompanies the gem, detailing the certification status, origin as Ceylon Sri Lanka, disclosure of heat treatment, clarity assessment and exact measurements, providing transparency for appraisal and resale. The Natural Gemstone Company stands behind the description and certification, and the inclusion pattern described above can serve as a practical fingerprint for authentication and for appreciation of the gem s natural history. This greenish blue zircon presents a considered balance of natural inclusions and expert cutting, offering an unmistakable signature that tells the story of its origin and formation.
