4.09 Ct. Chrysoberyl from Ceylon (Sri Lanka)

This 4.09 carat chrysoberyl from Ceylon is a study in clean, technical beauty, presented by The Natural Gemstone Company. The stone measures 9.34 x 8.26 x 5.53 mm and is executed in a classic emerald cut, which emphasizes parallel step facets and a broad table for controlled light return. Color is a yellowish green with medium intense saturation, an even distribution across the crown and pavilion, and an adamantine surface sheen. Clarity is graded as very slightly included when evaluated at eye level, confirming that the inclusions are minimal and do not interfere with the stone's overall transparency or faceting geometry. The polish is excellent, with crisp facet junctions and a mirror finish that optimizes internal reflections, and the garnet has not undergone any enhancement, confirming natural color and clarity characteristics as mined.

From a gemological and cut quality perspective, the emerald cut on this chrysoberyl is engineered to balance color and windowing, with step facets that create a series of broad, linear reflections that travel along the length and width of the stone. The dimension set produces a depth ratio near 59 percent, which sits within the range that preserves the medium intense color while preventing excessive windowing or light leakage. The crown facets are proportioned to deliver even dispersion and to maintain color saturation without creating isolated dark zones. On the pavilion, the step cuts converge to a well aligned culet area, supporting stable light return and the distinctive internal flash that collectors value in high quality chrysoberyl. The excellent polish and tight symmetry are visible at loupe magnification and contribute directly to perceived brilliance and face up color intensity in both daylight and artificial light.

Ethical sourcing has been a central criterion in the acquisition of this example, in line with The Natural Gemstone Companys procurement standards. The chrysoberyl was sourced in Ceylon, Sri Lanka, from vetted supply channels that maintain transparent mine to market documentation. Our partners adhere to local labor regulations and work practices designed to minimize environmental impact, including reclamation and controlled extraction methods. The absence of enhancement simplifies provenance verification, and we provide supporting documentation regarding origin and treatment history on request, enabling collectors to make informed decisions based on traceability. For buyers focused on conscious consumption, this stone represents a combination of geological rarity, artisanal cutting, and a supply chain that reduces the likelihood of unresolved ethical risks.

In practical application this chrysoberyl is well suited to high end jewelry that showcases step cut geometry, such as a four prong solitaire, a bezel set cocktail ring, or a tailored halo setting that complements the yellowish green hue without overpowering it. The gemologist recommended mounting approach emphasizes minimal metal coverage of the table to preserve light performance, paired with low profile prongs to secure the stone while maintaining the visual flow of the emerald cut. For designers and collectors seeking technical specifications, we can provide detailed facet maps and high resolution images, and our in house bench can offer precision re cut or custom mounting services while retaining the natural state of the gemstone. As with all pieces from The Natural Gemstone Company, each purchase is accompanied by our assessment of cut, clarity, and color, and we are available to discuss setting options that preserve both the physical integrity and the ethical provenance of the piece.
