2.89 Ct. Greenish Yellow Cabochon Chrysoberyl from Ceylon (Sri Lanka)

This is a precisely measured, translucent greenish yellow chrysoberyl, weighing 2.89 carat, presented in an oval cabochon form with dimensions 8.42 by 7.02 by 5.19 millimeters. The cabochon cut is executed with a pronounced domed profile and a well centered apex, a shaping choice that emphasizes the stone body color and maximizes transmission of light through the interior plane. Clarity has been graded as slightly included when evaluated at eye level, with minor internal features that are natural to chrysoberyl and that contribute to the gem translucency rather than detract from it. Color intensity is described as intense, the greenish yellow tone occupying a balanced position between citrus yellow and olive green, and the polish is excellent, yielding a smooth, reflective surface with minimal surface grain and clean optical response across the dome.

From a gemological perspective this specimen exhibits the key physical properties associated with chrysoberyl, which inform both handling and setting decisions. Refractive index ranges for chrysoberyl are approximately 1.746 to 1.755, with birefringence near 0.008, and these optical constants account for the gem clarity and the way light is subtly separated within the cabochon mass. Hardness is approximately 8.5 on the Mohs scale, offering robust wearability for ring and pendant applications, while specific gravity is in the vicinity of 3.73, a density that helps this medium sized cabochon feel substantial in the hand. The absence of enhancements is confirmed, so the color and translucency are entirely natural, which is a critical point for collectors and connoisseurs who require untreated material.

The cutting and finishing of this piece show classical lapidary technique applied to a Ceylon chrysoberyl blank. The cutter maintained even symmetry across the oval outline, controlled dome curvature to avoid windowing, and achieved a crisp transition at the girdle that facilitates secure bezel or collet mounting. Internal growth features are oriented such that the visual depth and color zoning read consistently when the stone is set face up, an important consideration for practical jewelry design. Slight inclusions are typical for natural chrysoberyl and in this example they create micro scattering that enriches visual depth without producing significant extinction. For settings, the cabochon profile is particularly suited to protective bezel work, as the rising dome and excellent polish lend themselves to tactile engagement and make the gem comfortable for everyday wear.

Heritage and provenance are central to the value proposition of this chrysoberyl. Origin is Ceylon Sri Lanka, a classic source for chrysoberyl that has supplied material for traditional South Asian jewelry and talismanic objects for centuries. Historically chrysoberyl from Sri Lanka was incorporated into signet rings and devotional ornaments, valued for its durability and its steady visual character under varied light. The use of chrysoberyl in these contexts emphasized both utility and symbolism, as the gem was often selected for objects intended to be worn daily and to last for generations. At The Natural Gemstone Company we highlight that this cabochon is consistent with that lineage, combining untreated natural color, disciplined lapidary execution, and Sri Lankan origin, making it suitable for collectors seeking an authentic material with documented regional heritage and for jewelers aiming to create pieces that reference classical South Asian design while meeting modern standards of technical gemcraft.
