11.67 Ct. Cabochon Tiger's Eye from South Africa

One beautiful opaque 11.67 carat oval shape golden brown tiger's eye measures 18.07 by 13.06 by 7.26 millimeters, presented in a classic cabochon cut with a pronounced domed crown and a stable flat pavilion, the length to width ratio of approximately 1.38 yields an elegant oval silhouette that sits well in both bezel and open prong settings, the cabochon profile is deliberately oriented to the stone s microstructure so that the chatoyant banding reads uniformly across the surface, clarity is graded opaque at eye level, color intensity not applicable given the natural golden brown palette, polish is excellent, enhancement none, provenance South Africa. The gem exhibits balanced proportions and substantial depth at 7.26 millimeters, which contributes to a strong, lively chatoyancy when moved under directional light, the well executed domed surface minimizes light leakage and maximizes the linear silk effect that defines high quality tiger s eye, the overall finish is even and free of polish pits or laps, confirming careful lapidary control during the final stages of cutting and finishing.

The internal inclusions that define this specimen are its most diagnostic and characterful features, the stone displays parallel fibrous structures formed by silica replacement of amphibole fibers, the resulting needle like or silky bands run consistently along the length of the oval and produce the trademark cat s eye shimmer, these internal silk planes act as a unique identifier, their spacing, curvature and contrast create an inclusion fingerprint that can be referenced in provenance reports and under magnification they reveal subtle variations in band thickness and reflectivity that are individual to this piece. From a craftsmanship perspective the cabochon was preformed and oriented to align the fiber axes with the domed axis, progressive sanding through finer grits established the smooth curvature, and final polishing to a mirror finish enhances the schiller effect without resorting to enhancement, the absence of treatment preserves natural stability for long term wear. For technical buyers and lapidary collectors who value exacting detail and natural origin, this South African tiger s eye offers a combination of measurable dimensions, predictable optical behavior, and a distinctive inclusion pattern, for availability, detailed imagery and certification, please contact The Natural Gemstone Company.
