7.13 Ct. Cabochon Tiger's Eye from South Africa

One beautiful opaque 7.13 carat oval shape golden brown tiger's eye is presented, dimensions 18.11 x 13.12 x 4.10 mm, cabochon cut, clarity grade opaque evaluated at eye level, color intensity n a, excellent polish, no enhancement, origin South Africa, supplied by The Natural Gemstone Company. The stone sits within the classic cabochon form, with a gently domed face and a well proportioned pavilion that together emphasize the material structure and natural silk like chatoyancy. Photographs show a warm, even presentation with linear banding running parallel to the long axis, and with surface reflections that confirm the stated polish quality. Weight and measurements are consistent with a substantial finger or pendant gem, and the combination of carat weight and millimeter dimensions offers a clear sense of scale for use in bespoke or production settings.

Visually the piece displays the characteristic optical phenomena associated with tiger's eye, commonly referred to as the cat eye effect or chatoyancy. Bands of golden honey and deeper brown run in a parallel fibrous pattern, producing a shifting ocular band that travels across the dome as viewing angle or light source changes. The cabochon cut is the standard approach for this material, intentionally chosen to align the fibrous structure with the dome to maximize the chatoyant band. Surface polish is described as excellent, which aids the movement and definition of the light band, and the overall tone remains in the golden brown family, with subtle striations visible within the opaque body. The visual balance between warm mid tones and darker accents creates a versatile appearance, suitable for both classic and contemporary jewelry designs.

From a gemological perspective tiger's eye is a form of microcrystalline quartz, with mechanical and physical properties that make it readily wearable. Typical Mohs hardness is 7, and specific gravity generally falls in the range of 2.64 to 2.71, values that contribute to reasonable abrasion resistance and stable handling for daily wear. The material lacks true cleavage, and fractures are typically conchoidal or uneven, which informs decisions about setting and fabrication. Given the dimensions 18.11 x 13.12 x 4.10 mm and the cabochon profile, recommended settings include bezel set rings, drop style pendants, and secure closed back mountings that protect the lower surface while allowing the dome to present. For rings, consider a protective bezel to reduce exposure to edge impacts, while pendants and earrings can be designed with open back or gallery details to facilitate light interaction and to showcase the chatoyant band.

Care and authentication notes are provided to support long term satisfaction and appropriate handling. The stone has no recorded enhancements, and this untreated status is reflected in its natural color and structural characteristics. Cleaning may be performed with warm soapy water and a soft brush, followed by gentle drying with a soft cloth, avoiding prolonged exposure to strong chemicals, acids, and extreme heat. Ultrasonic cleaners are typically not recommended for stones with chatoyant fibrous structure, unless specifically evaluated and approved by a qualified lapidary or jeweler. Storage in a separate soft pouch or compartment will protect the polished surface from abrasion.
