1.07 Ct. Greenish Brown Cabochon Cat’s Eye Chrysoberyl from Ceylon (Sri Lanka)

This translucent greenish brown chrysoberyl, weighing 1.07 carat, represents a premium specimen within the cat s eye category, and reflects both natural origin and refined lapidary control. The oval shape measures 5.54 by 5.29 by 3.89 mm, dimensions that yield an ideal balance between visible surface area and internal depth for cabochon mounted applications. The cabochon cutting style has been executed to optimize chatoyancy while preserving weight, and the result is a compact stone that reads larger than its carat weight might suggest when set. Origin confirmed from Ceylon Sri Lanka, this piece is untreated, with no enhancement applied, which preserves intrinsic color zoning and the natural interaction between inclusions and light. At 1.07 carat this chrysoberyl sits in a premium weight class for cabochon chatoyants, offering collectors and designers a size that is substantial for rings and pendants while still providing excellent optical definition of the cat s eye band.

From a lapidary and gemmological perspective this cabochon displays several refinement markers that contribute to its premium classification. The dome profile has been shaped to a controlled curvature that concentrates and sharpens the chatoyant band, while the pavilion has been carefully removed to retain sufficient thickness for durability, at a measured depth of 3.89 mm. The polish is described as excellent, producing a high surface luster that allows the internal band to present with crisp contrast against the greenish brown body color. Clarity is graded as very very slightly included, evaluated at eye level, and this scarcity of disruptive inclusions permits the light to form a coherent reflection across the fiber oriented inclusions that generate the cat s eye effect. Technical properties inherent to chrysoberyl such as robust hardness and a refractive index that falls in the upper mid range for gem materials contribute to the stone s ability to hold a fine polish and display sustained brilliance under direct illumination.

The cat s eye phenomenon, or chatoyancy, in this piece is a primary visual attribute and a key determinant of value. The band of light is formed by a dense, parallel orientation of fine inclusions within the chrysoberyl crystal lattice, most commonly acicular fibers that are aligned during growth. In this specimen the band appears as a single, well centered streak of reflected light that traverses the cabochon horizontally, and its sharpness indicates a high degree of parallelism and a uniform inclusion distribution across the gem s cross section. When illuminated, the band reads as a bright, narrow line whose intensity and contrast are enhanced by the stone s intense body color, allowing the observer to perceive the eye even under diffused light. The band moves smoothly across the dome when the stone or light source is tilted, demonstrating a coherent optical plane and confirming the quality of both the rough orientation at the time of cutting and the subsequent polish. The visible cat s eye is neither diffuse nor fragmented, and that integrity is a distinguishing feature of superior chatoyant chrysoberyl.

For designers and collectors considering settings and long term handling, the 1.07 carat weight combined with the 5.54 by 5.29 mm table footprint makes this cabochon suitable for a refined solitaire ring, a bezel set pendant, or as a focal inlay in a custom men s or women s piece where the cat s eye can be presented in natural directional light. The cabochon cut preserves mass and maximizes the visible band, and because no enhancement has been applied the color and chatoyancy will respond predictably to changes in mounting and lighting. The Natural Gemstone Company presents this chrysoberyl as a natural, untreated gem from Sri Lanka, offering documentation of dimensions, weight, and the eye level clarity assessment. In terms of maintenance the stone s hardness supports regular wear, though recommended practice includes protecting the dome from abrasive contact and periodic cleaning with mild detergent and warm water to maintain the excellence of the polish. This 1.07 carat greenish brown chrysoberyl exemplifies the intersection of geological rarity and lapidary precision, and it is offered as a premium grade cat s eye with the optical and physical attributes to satisfy knowledgeable buyers and connoisseurs.
