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

This translucent 1.10 carat oval yellowish green chrysoberyl from Ceylon Sri Lanka is a classical example of a well proportioned cabochon cut gemstone, measuring 5.77 x 5.29 x 3.95 mm, with intense color intensity and an excellent polish, supplied by The Natural Gemstone Company. The gem is untreated, with no enhancement, and carries a clarity grade of very slightly included when evaluated at eye level, which means that the stone presents only minor natural features that do not detract from its overall visual appeal when set. The cabochon cutting style maximizes the interplay between the body color and the optical phenomenon for which chrysoberyl cat's eye is prized, making the color appear richer and more luminous across the domed surface, while the excellent polish ensures an even, reflective surface that showcases the stone in jewelry applications.

The unmistakable signature of this specimen is its cat's eye effect, or chatoyancy, produced by a concentration of fine, parallel inclusions aligned within the crystal structure, typically acicular mineral fibers and narrow growth tubes, which act together to reflect light as a single bright band. In this stone that band is distinctly visible across the dome, well centered and relatively sharp, moving crisply with the angle of incident light, a feature that elevates its desirability among connoisseurs. These inclusions create a silk like plane that not only forms the luminous eye, but also gives the gem a fingerprint like identity, each banding pattern being unique to the crystal. For the educated buyer, attributes such as a well centered single eye, strong contrast between the band and the body color, and the absence of treatments are primary value drivers, and this chrysoberyl excels in all of these respects. The piece is ideal for a bespoke ring or pendant setting that preserves the orientation of the band, and routine care should favor gentle cleaning and avoidance of harsh chemicals or ultrasonic machines to protect the integrity of the natural inclusions that give this gem its character.
