2.62 Ct. Green Chrysoberyl from Ceylon (Sri Lanka)

This gemstone is a transparent green chrysoberyl, weighing 2.62 carats, presented in a round shape with precise dimensions of 8.45 x 8.43 x 5.26 mm. The cutting style is faceted, executed as a mixed brilliant cut to combine pavilion depth and crown faceting for optimum light return. Color is classified as intense, with a saturation and tone that remain stable under standard daylight viewing. Clarity is graded very slightly included, evaluated at eye level, indicating that inclusions are minor and do not detract from overall transparency or visual appeal. The polish is noted as excellent, producing crisp facet junctions and a smooth table surface. Enhancement status is none, and origin is Ceylon Sri Lanka, a region recognized for consistent chrysoberyl quality and classic green tones. The Natural Gemstone Company provides this technical profile as part of our standard disclosure, ensuring the description is consistent with laboratory style reporting and our internal inspection records.

The journey of this chrysoberyl began within the gem fields of Ceylon Sri Lanka where chrysoberyl forms in pegmatitic and alluvial environments, often associated with weathered metamorphic host rock. Local prospecting and artisanal mining techniques led to the recovery of rough material from river gravels and secondary deposits, where individual pebbles were identified by color and heft. Initial sorting occurred close to the extraction site, where experienced gem sorters separated potential gem quality pieces based on transparency, color zoning, and the absence of obvious cracks. Weight and rough dimensions were recorded at the field level, and a selection was made for stones suitable for round cuts with balanced proportions. Throughout recovery and initial handling, chain of custody documentation was maintained, including mine locality records and transport manifests, to preserve provenance. The Natural Gemstone Company maintains relationships with sourcing partners in Sri Lanka to support traceability and to verify that material is procured in compliance with local regulations and standard ethical practices.

Upon arrival at the lapidary studio, the rough chrysoberyl underwent a detailed assessment to determine cutting strategy that would maximize yield while respecting optical characteristics. The lapidary plan emphasized a mixed brilliant cut, combining a faceted crown designed to enhance color saturation with a pavilion geometry that promotes internal reflection and brilliance. Orientation of the rough played a significant role in determining facet layout, with the cutter aligning key facets to favor even color distribution and to minimize the visual impact of any internal features. Preforming removed surface irregularities, then precise faceting established symmetry and balance, targeting the finished diameter and depth that produced the final weight of 2.62 carats. Polishing was completed using progressively finer abrasive compounds until an excellent polish was achieved, evident in the mirror like facet surfaces and defined facet junctions. No treatment or enhancement was applied at any stage, preserving the stone as a natural specimen. The resulting dimensions, 8.45 x 8.43 x 5.26 mm, reflect a careful compromise between conserving carat weight and achieving the optical properties expected from a high quality mixed brilliant facet geometry.

After cutting and polishing, the gemstone entered a formal inspection and grading process, where measurements and assessments were recorded to standardize its description for market presentation. Weight was confirmed as 2.62 carats, and dimensions were verified with calibrated measuring tools to ensure accuracy. Clarity assessment at eye level returned a very slightly included grade, with inclusions described as minor and generally only perceptible under specific viewing angles or with careful observation. Color intensity was evaluated under standardized lighting conditions, with a consensus that the green tone and saturation were intense and evenly distributed. Cut quality was reviewed for symmetry, facet alignment, and crown to pavilion balance consistent with mixed brilliant design principles. Polish resulted in an excellent designation based on surface finish and lack of polish lines. Origin attribution to Ceylon Sri Lanka was supported by purchase documentation, field records, and characteristic material properties that align with regional gemological profiles. The Natural Gemstone Company compiles a certificate of attributes for each gemstone, documenting weight, dimensions, cut style, clarity grade, color intensity, polish, treatment status, and origin, to provide buyers with transparent, verifiable information.

In preparing this chrysoberyl for market, careful handling, secure packaging, and clear communication of its technical profile were prioritized. Imaging was carried out using standardized gem photography to capture true color representation and to illustrate the inclusion characteristics that informed the very slightly included clarity grade. The stone was mounted in a protective setting for transit, with cushioning to prevent facet contact and abrasion. Recommendations for care highlight routine cleaning with a soft brush, mild detergent, and warm water, avoiding harsh chemicals and extreme heat that can affect mounting materials rather than the gem itself, noting that chrysoberyl is durable but benefits from prudent handling. Suggested settings favor designs that expose the table and crown to light to showcase the mixed brilliant cut performance, while also securing the stone to protect the girdle from impact. For clients seeking provenance and full disclosure, The Natural Gemstone Company stands ready to provide the certificate and provenance documentation compiled during the gem journey, and to assist with technical questions regarding setting options, maintenance, and long term care based on the stone characteristics recorded during cutting and grading.
