4.27 Ct. Cabochon Tiger's Eye from Ceylon (Sri Lanka)

One beautiful opaque 4.27 carat round golden brown tiger eye is presented, with precise dimensions of 9.95 by 9.98 by 5.47 mm, a classic round shape finished in a cabochon cutting style, and an excellent polish that emphasizes surface luster and optical effect. The gem is described as golden brown with color intensity listed as not applicable, and it is supplied without any enhancement, reflecting its natural state. The cabochon profile provides a gently domed face and a well proportioned base, dimensions that are suitable for a variety of jewelry applications. Origin is Ceylon Sri Lanka, an established source for fine varieties of chalcedony derived gems, and the specimen displays uniform opacity with subtle banding and tonal variation that are characteristic of tiger eye. Weight, proportions, cut, and polish are specified to allow accurate assessment for design and setting, and the absence of treatments ensures that the recorded measurements and visual attributes represent the stone as it occurs in nature.

Optically, this tiger eye exhibits the chatoyant ribbon like sheen that defines the material, a silky band that moves across the domed surface when the stone is tilted under directional light. This effect arises from the fibrous structure within the silica matrix, a result of pseudomorphic replacement of crocidolite by quartz, which produces parallel fibrous inclusions that reflect light in a concentrated band. The cabochon cut maximizes this phenomenon by providing a smooth, uninterrupted plane for the band to traverse, and the excellent polish enhances reflectivity while minimizing surface distortion. From a durability perspective the gem is a variety of quartz with an expected Mohs hardness of about 7, a balance of resilience and workability that makes it appropriate for daily wear in rings, bracelets, and pendants when set with sound design principles. The material stability is enhanced by the lack of enhancements, so color and chatoyancy are inherent and stable under normal conditions of wear and display.

Over time the natural beauty of this gemstone will continue to captivate, due to its intrinsic optical properties and durable mineral composition, provided basic care is observed. Regular cleaning with warm water, mild soap, and a soft cloth will maintain surface luster, and routine inspection of the setting will protect the domed face from abrasion and impact. For maximum protection in jewelry applications a bezel or low profile setting is recommended, as these settings reduce exposure of the girdle and provide mechanical security for the cabochon. Avoidance of prolonged exposure to harsh chemicals, abrasive cleaners, and extreme thermal shock will preserve polish and chatoyancy, and professional re polishing can restore surface finish if light wear appears over many years. For provenance and sourcing transparency this tiger eye is offered with clear origin information from Ceylon Sri Lanka, and The Natural Gemstone Company stands by the documented specifications, providing accurate measurements, cut description, and enhancement status to support informed selection and long term enjoyment.
