7.25 Ct. Cabochon Tiger's Eye from South Africa

This listing describes one natural tiger's eye, weighing 7.25 carats, presented in an oval shape and cut as a cabochon, with precise dimensions of 17.87 x 13.20 x 4.26 mm. The gem displays a golden brown body color with distinct parallel chatoyant bands that produce a silky, cat eye effect when light crosses the surface, and it is classified as opaque. The cabochon cutting style emphasizes the linear fibrous structure and the central band of reflected light, and the stone has been finished to an excellent polish that provides a smooth, glossy surface and crisp chatoyancy. There has been no enhancement applied to this specimen, and the origin is South Africa, a well known source for quality tiger's eye material.

From a material standpoint, tiger's eye is a variety of quartz in which pseudomorphic replacement of crocidolite fibers by silica has preserved the fibrous, parallel structure responsible for the characteristic chatoyancy. This specimen exhibits a well defined eye, consistent banding, and a rich golden brown tone that ranges in saturation across the table and girdle areas, which is typical for natural material and indicative of its formation history. The cabochon profile is proportioned to maximize the optical effect while maintaining durability, the height of 4.26 mm providing a comfortable dome that will hold up to normal wear when set appropriately. Surface quality is excellent, with a clean polish and minimal surface irregularities visible to the naked eye, and internal characteristics are natural inclusions consistent with tiger's eye, not flaws resulting from treatment or enhancement.

This tiger's eye is suitable for a variety of jewelry applications, including rings, pendants, and brooches, as well as for collectors and lapidary projects where a strong chatoyancy is desired. Because the stone is opaque and presents a stable silica composition, it responds well to traditional metal settings, and protective bezel settings are advisable for pieces subject to frequent impact. Care recommendations are straightforward, avoid prolonged exposure to harsh chemicals and abrasive cleaning methods, clean with warm soapy water and a soft cloth, and avoid ultrasonic cleaners to preserve the polish and optical sheen. The Natural Gemstone Company offers this piece as a natural, unenhanced example of South African tiger's eye, provided with accurate dimensional and weight specifications to assist in design planning and appraisal, and the description above is intended to convey the gemological and practical attributes in clear, factual terms.
