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

This 0.88 carat oval shape yellowish green chrysoberyl is presented as a well proportioned cabochon, with dimensions of 5.55 by 5.13 by 3.12 millimeters, a translucent body, and an excellent polish, supplied by The Natural Gemstone Company. The gem displays a medium color intensity that reads as a soft yellowish green in most lighting, and the cabochon cutting style is intentionally chosen to maximize the cat eye, or chatoyancy, that defines the stone. Clarity is graded included, evaluated at eye level, which means the internal features are visible to a trained observer without magnification, and those features are in fact the sources of the attractive chatoyant effect. No enhancement has been applied to this chrysoberyl, and the piece is a natural product of Ceylon, Sri Lanka, a classic origin known for producing chrysoberyls with fine optical phenomena and stable color.

For an educated buyer the combination of material, cut, and origin provides clear metrics of value and desirability, and these can be compared against standard chrysoberyl benchmarks. Chrysoberyl rates high on the Mohs scale for hardness, making it durable for daily wear, and genuine chatoyant specimens are rarer than ordinary faceted gems because the required parallel fibrous or needle like inclusions are not common in every deposit. The cabochon form concentrates light reflection into a single, focused band, and the excellent polish on this example increases the sharpness and contrast of that band. The medium color intensity sits in a range that complements the cat eye rather than overpowering it, so the band remains the visual focal point while the soft yellowish green body color provides an attractive backdrop that will harmonize with both warm and cool metals.

Chatoyancy in chrysoberyl is a directional optical phenomenon caused by a fine, parallel alignment of needle like inclusions, or by parallel fibrous structures within the crystal, these act collectively like a miniature cylindrical mirror that reflects a concentrated band of light across the dome of the cabochon, the band appears as a sharp, moving line when the stone or the light source is rotated, and in high quality examples such as this piece the band is distinct and continuous across the surface. The visibility and sharpness of the band depend on the alignment of the inclusion structures relative to the gem axis and the cutter oriented the cabochon to present the band across the longest dimension of the oval shape, creating a pleasing linear effect that is easily appreciated when the gem is set or held. Because the clarity is included, the same internal structures that might be considered imperfections in other gems are the very reason this chrysoberyl is prized as a cat eye, and the overall visual balance between body color, transparency, and the light band is what discerning collectors seek.

Lighting conditions influence the appearance of this chrysoberyl in predictable and beautiful ways, and understanding these effects helps a buyer anticipate real world performance when the gem is set in jewelry. In strong direct sunlight the medium yellowish green body color brightens and the cat eye band becomes very crisp, the contrast between the band and the surrounding dome is greatest in high angle daylight, making the optical phenomenon highly visible when the wearer moves. In diffuse natural daylight, such as under an overcast sky or indoors near a window, the body color reads softer and more pastel, and the cat eye remains visible but slightly more subdued, offering a subtle, elegant look. Under warm incandescent lighting the yellow component of the body color is emphasized, so the stone may read as a warmer yellow green and the band can take on a gentle golden rim, whereas under cool white LED lighting the green aspect can appear slightly clearer, with the band maintaining a silvery white appearance that stands out against the cooler body tone. In low or candlelight the overall translucency reduces intensity, but the band can become a ghostly bright line that moves with motion, offering a dramatic effect for evening wear. For photography and display a single small directional light source placed behind the camera and above the stone will often reveal the most well defined band, and in mounted jewelry the cutter has oriented this cabochon so the band runs across the finger when set as shown in reference images.

Practical considerations include the recommended orientation and mounting options to best showcase the chatoyancy and to protect the cabochon, a bezel setting is particularly suitable because it secures the stone while leaving the dome exposed to light, and a low profile mount helps maintain visibility of the cat eye for everyday wear. Because this chrysoberyl is untreated and originates from Ceylon, Sri Lanka, it holds intrinsic value for collectors who prioritize natural provenance and minimal intervention, The Natural Gemstone Company stands behind the description and the natural state of the gem, and we encourage buyers to request photography under the lighting conditions they prefer, or to request a short video that demonstrates the movement of the cat eye. For those choosing this stone for a bespoke commission or a modern setting, the compact size and 0.88 carat weight make it suitable for delicate rings, small pendants, or accent pieces that benefit from a striking optical focal point rather than large color saturation. Overall this yellowish green cabochon chrysoberyl represents a harmonious combination of natural optical character, classic origin, and durable material qualities, making it an appealing acquisition for collectors, connoisseurs, and anyone seeking the unique visual drama of a true cat eye.
