7.36 Ct. Green Cabochon Chrysoberyl from Ceylon (Sri Lanka)

This translucent green chrysoberyl weighs 7.36 carats, and presents as an oval cabochon measuring 11.83 x 8.31 x 7.23 mm, cut and finished to emphasize optical phenomena rather than faceting. The cutting style is a high domed cabochon with a smooth symmetric profile, crafted to follow the crystal orientation so that the fibrous inclusions lie parallel to the long axis. Clarity is graded slightly included at eye level, and those internal features are integral to the stone character and the cat s eye effect. Color intensity is faint green, subtle and even across the dome, and the surface shows an excellent polish that yields clean light return and minimal surface disturbance. This gem is natural from Ceylon Sri Lanka, and it has not been subjected to any enhancement, which preserves its natural body tone and internal structure.

The cat s eye phenomenon or chatoyancy is expressed as a single, well defined band of light that traverses the cabochon when illuminated, the band appearing tight and centered in most viewing angles. This band results from fine, parallel, needle like inclusions that act as reflective planes, typically rutile or similar silk like inclusions, aligned within the chrysoberyl matrix. When the stone is rotated, the band of light translates smoothly across the dome, a sign of uniform inclusion orientation and careful lapidary control. The lapidary process for this specimen prioritized orientation and symmetry, preforming the rough to align the inclusion axis with the long dimension of the oval, then bringing the dome to a precise curvature before the final stages of polishing, producing a crisp cat s eye line and excellent surface luster.

The Natural Gemstone Company presents this piece with respect for the heritage of Ceylon chrysoberyl, a material historically employed as protective talismans, ceremonial ornaments, and astrological gems in Sri Lankan tradition, prized for both durability and optical intrigue. Collectors and connoisseurs will appreciate the combination of an untreated origin, a classic oval cabochon geometry, and a distinctly mobile chatoyant band, making this gem particularly well suited to a bezel or closed back setting, where the cabochon profile and the cat s eye are displayed to best effect.
