From a gemological perspective this chrysoberyl presents attributes that matter to educated buyers and connoisseurs, chrysoberyl is a durable gem species with a Mohs hardness of 8.5, making it suitable for everyday wear in rings, pendants, and other jewelry where a hard surface is important, its refractive index range typically runs roughly from 1.746 to 1.755, with low to moderate birefringence, and a specific gravity in the high three range, these physical properties contribute to a lively but controlled light return in faceted material, and in cabochons they help produce a crisp and well defined chatoyant band when present, the cabochon form chosen for this piece is the optimal way to display any silk like alignment of inclusions or structural features that create a cat eye effect, the images supplied show a clear bright band of reflected light that traverses the dome, that optical feature is an additional visual asset when it is well centered and sharp, polish quality is critical for such effects, and the excellent polish reported here ensures the light band reads cleanly and with good contrast.

Coloration in chrysoberyl is produced by trace element chromophores, commonly iron and in some instances chromium, the yellowish green tone of this example is consistent with iron related absorption features, the hue and saturation are unusually strong for a cabochon of this weight, which adds to its market value, Sri Lanka or Ceylon is renowned for producing chrysoberyl with attractive color and classical tones, provenance matters to many buyers because locality can influence both aesthetic expectations and long term value, natural unenhanced stones from classic localities command preference among collectors and investors who value natural state material, the fact that this chrysoberyl has not been heat treated or otherwise enhanced is an important selling point, treatments can alter color and clarity in ways that are permanent and visible under gemological testing, by contrast a natural color that is stable without treatment is easier to verify and generally holds value better in secondary markets.
