1.62 Ct. Pink Spinel from Tanzania

At The Natural Gemstone Company I am pleased to present a transparent 1.62 carat oval pink spinel, with exact dimensions of 7.72 by 5.69 by 4.73 millimeters, a classic oval silhouette that balances face up presence with wearable proportions. The gem displays intense color intensity, a vivid pink saturation with lively medium to medium deep tone that reads exceptionally well against both warm and cool metal choices. Cut as a mixed brilliant, the stone features a brilliant style crown that maximizes scintillation, in combination with a pavilion geometry calibrated to retain saturation and reduce windowing. Clarity is graded very slightly included, evaluated at eye level, and the polish is excellent, yielding crisp facet junctions and high reflectivity across the table and crown facets. This specimen is unenhanced, with no treatments reported, and the documented origin is Tanzania, a source known for producing richly colored spinels with clean crystal lattices and strong, consistent hue.

The mixed brilliant faceting on this oval spinel is executed with technical precision, featuring a proportional crown height and crown angle tuned to the gem’s refractive properties, and a pavilion depth that avoids excessive leakage while preserving color saturation. The crown presents a series of star and highlight facets that break white light into lively flash, while the pavilion facets are arranged to direct return light efficiently to the viewer, creating a balance of brilliance and color. Symmetry is carefully controlled, with even facet alignment around the girdle and a girdle profile that supports secure setting without introducing unnecessary weight loss. The pavilion girdle relationship and culet treatment reflect an attention to light interaction, producing controlled caustics and an even window that prevents broad open areas that would weaken perceived color. Polishing technique is evident in the fine facet surfaces, where excellent polish minimizes micro abrasions and enhances luster, contributing to the gem appearing highly lively under both point and diffuse illumination. For buyers assessing optical performance, note that spinel is isometric and singly refractive, which simplifies light behavior relative to biaxial species, and that the stone’s hardness around Mohs 8 provides durable wear for everyday settings while still responding well to precise cutting lines.

Inclusions present within this spinel act as natural identifiers and intrinsic character markers, rather than detractors from value. Observed features include small crystalline inclusions and minute pinpoint features that are internal to the growth structure, occasionally presenting as reflective platelets that catch light and produce subtle internal contrast. These inclusion patterns are consistent with natural crystallization in the host environment, and they provide a unique internal fingerprint that can be used for verification and provenance studies, especially when combined with the gem’s Tanzanian origin. Some inclusions demonstrate selective orientation which reveals growth zoning under certain angles of illumination, and these zones can intensify color around facet edges, adding micro variance that appears lively and organic. Because the gem is untreated, these internal markers remain stable and are part of the stone’s authentic narrative, offering both visual interest and a means of tracing individual identity in future appraisals. For practical handling and setting recommendations, a protective bezel or secure claw setting will both preserve the integrity of the girdle and display the table optimally, and routine care with warm soapy water and a soft brush will maintain polish without risk to the stone. At The Natural Gemstone Company we welcome informed buyers who value transparent documentation, and this 1.62 carat Tanzanian pink spinel exemplifies meticulous cutting, natural character through inclusions, and enduring color performance suitable for a fine collection piece.
