6.13 Ct. Yellowish Green Cabochon Cat’s Eye Chrysoberyl from Ceylon (Sri Lanka)

This translucent oval chrysoberyl weighs 6.13 carat, and measures 12.36 x 8.87 x 6.82 millimeters, and it presents a refined yellowish green hue that reads as intense and lively to the eye. The stone has been expertly fashioned as a cabochon, a traditional cut for chatoyant gems, and exhibits an excellent polish and symmetrical dome that maximizes its optical performance. Clarity is graded as very slightly included when evaluated at eye level, indicating that inclusions are minimal and do not distract from the overall visual appeal. The specimen is unenhanced, a natural gem with no heat, diffusion, or other treatments, and it originates from Ceylon Sri Lanka, a region renowned for producing some of the finest chrysoberyls in the trade. The Natural Gemstone Company is proud to present this gem as a stand alone collector piece or as the centerpiece for a bespoke high end jewelry commission.

From a gemological perspective this chrysoberyl checks all of the boxes that educated buyers look for, beginning with color intensity, and extending to cut quality and optical phenomena. The cabochon cut is the correct choice to reveal and sharpen the cat s eye effect known as chatoyancy, which in this stone appears as a single bright band of light that crosses the surface when illuminated. Chatoyancy in chrysoberyl is produced by tightly aligned, needle like inclusions that act like tiny reflectors, and in this material those inclusions are fine and parallel enough to create a distinct, well defined eye. The dome height, polish, and oval outline have been executed to center and stabilize that band, so the eye remains centered as the gem is tilted, and the intensity of the color serves as an ideal background that contrasts with the luminous stripe. The very slightly included clarity grade means light transmission is healthy, translucency allows the eye to be bold without the stone appearing cloudy, and the excellent polish ensures the band of light remains clean and uninterrupted.

Collectors and connoisseurs assess chrysoberyl using a consistent set of criteria, and this specimen performs exceptionally across that rubric. Color intensity is a primary determinant of value, and the yellowish green tone here is both saturated and evenly distributed, avoiding zoning or brownish overtones that can diminish appeal. The single, sharp cat s eye is a major value driver, because a strong, centered eye is uncommon at this size, and because it communicates quality of both material and lapidary work. The lack of enhancement elevates provenance and market confidence, particularly for buyers who prioritize natural state and geological origin. Sri Lankan chrysoberyl has a long and verifiable history in the gem market, and pieces from that origin are often sought after for their combination of fine color, durability, and classic aesthetic. Hardness and toughness inherent to chrysoberyl make it suitable for wearable jewelry as well as for display, and the 6.13 carat weight places it in a range where both visual presence and investment potential are meaningful, without reaching size classes that attract excessive premiums solely for scale.

For a high end collection this chrysoberyl is an exemplary addition, because it merges connoisseur grade optical character with clean gemological credentials. The cabochon oval format suits an array of settings, from elegant bezel framed rings to museum style pendants or bespoke display mounts, and the optical motion of the cat s eye adds an interactive quality that is prized by collectors who value dynamic gems. The Natural Gemstone Company stands behind the information provided, and we can supply high resolution imagery and video that demonstrate the chatoyancy and confirm the centered band of light under directional illumination. For those seeking certification, we offer support for independent laboratory reports and can advise on the best setting approaches to preserve and highlight the eye while ensuring structural security. In summary this 6.13 carat, translucent, yellowish green Ceylon chrysoberyl, unenhanced, with a very slightly included clarity grade, intense color, excellent polish, and a precise cabochon that produces a sharp cat s eye, represents a rare combination of aesthetic beauty, scientific interest, and lasting value for the informed buyer.
