4.29 Ct. Yellowish Green Chrysoberyl from Ceylon (Sri Lanka)

This listing describes a single natural chrysoberyl weighing 4.29 carats, presented in a cushion shape with dimensions 10.96 by 8.37 by 5.65 millimeters. The stone displays a yellowish green hue with intense color intensity, a mixed brilliant cut, and an excellent polish. Clarity is graded as very very slightly included, evaluated at eye level, and the gem is free of any enhancement. Origin is Ceylon Sri Lanka, and the material is natural chrysoberyl, the mineral composed of beryllium aluminum oxide BeAl2O4. With a hardness of 8.5 on the Mohs scale and an adamantine luster, this gem combines durable wearability with strong light performance, making it suitable for fine jewelry applications where both resilience and optical presence are required.

The mixed brilliant cut used for this cushion shaped stone typically combines a brilliant style crown with a pavilion that optimizes light return and face up appearance. At the noted proportions, the gem presents a substantial face up area with good depth for secure mounting, while the excellent polish enhances the surface luster and scintillation. The clarity grade of very very slightly included, evaluated at eye level, denotes minute natural inclusions that do not materially affect transparency or brilliance to an unaided observer, yet they contribute to the stone’s natural fingerprint. The intense yellowish green color is even across the table, and the origin of Ceylon Sri Lanka is consistent with the regional geology that produces chrysoberyls with clean crystallinity and attractive, saturated tones.

When compared with lab grown counterparts, natural chrysoberyl offers several distinctive advantages. Laboratory produced gems can exhibit exceptional uniformity in color and clarity, which can be desirable for some applications, however natural stones retain rarity and geological provenance that carry intrinsic and collectible value. Natural inclusions and subtle internal growth features serve as reliable indicators of formation environment, and they provide each piece with uniqueness that cannot be identically replicated in a factory setting. Natural stones, particularly those with documented origin and without enhancement, tend to hold market preference among collectors and connoisseurs, and they may offer stronger long term value retention. Furthermore, the Ceylon origin of this chrysoberyl imparts trace element and growth signatures that are of interest to gemological study and to clients who value regional provenance.

The Natural Gemstone Company provides full disclosure regarding origin, treatment status, and quality attributes, and this 4.29 carat cushion chrysoberyl is presented as a natural, untreated example from Ceylon Sri Lanka. For purchasers seeking independent verification, a gemological report from a recognized laboratory can document identity, origin indicators, and the absence of enhancement. In technical and aesthetic terms this specimen combines robust physical properties, precise cutting, intense natural color, and minimal inclusions, characteristics that distinguish it from many lab grown alternatives and that align with standards expected in museum quality and investment grade collections.
