0.68 Ct. Spinel from Tanzania

This transparent 0.68 carat radiant shape pink spinel from Tanzania, offered by The Natural Gemstone Company, combines measured precision with natural rarity, presenting exact dimensions of 5.94 by 4.77 by 2.59 millimeters. The gem carries a clarity grade of very very slightly included evaluated at eye level, and it presents as effectively eye clean with only minute internal characteristics that do not interfere with the visual performance. Color is classified as medium intense in intensity, delivering a well saturated pink that balances vividness with a desirable lightness of tone. The piece is untreated, enhancement none, and exhibits an excellent polish that underscores the cutter s attention to facet finish and junction crispness, attributes that preserve luster and reduce surface wear over time.

The radiant cut executed on this spinel is a hybrid faceting architecture, combining the pavilion and crown brilliance of a round brilliant pattern with the elegant rectilinear outline and clipped corners typical of the radiant family. The cutter has maintained a proportion set that yields a length to width ratio of approximately 1.25 to 1, producing a slightly elongated rectangular outline that is versatile in jewelry design. Depth is calibrated to approximately forty eight percent of the average of the girdle dimensions, an optical proportion that maximizes internal light return while maintaining face up spread relative to weight. Facet symmetry and alignment are precise, with well controlled table and crown plane relationships that create a lively interplay of broad flashes and smaller scintillation points, especially visible when the stone is oriented beneath a direct light source. The excellent polish enhances facet transparency and contributes to a clean window through the crown, which allows the medium intense pink saturations to read uniformly across the table without distracting reflections.

From a gemological and craftsmanship perspective, this pink spinel exemplifies the intersection of technical cutting decisions and natural material qualities that discerning buyers value as an investment in beauty and workmanship. Spinel s inherent hardness and toughness, rated at eight on the Mohs scale, confers durability that is suitable for daily wear in rings and bracelets, while the untreated provenance from Tanzania increases collectible appeal because it preserves the stone s natural optical properties. The cutter s restraint in maintaining a modest pavilion depth and balanced crown angles demonstrates an intent to optimize both brilliance and face up color, a trade off that seasoned cutters manage to capture the fullest expression of a spinel s hue without compromising sparkle. The very very slightly included clarity at eye level means light travels through the pavilion with minimal obstruction, producing consistent color saturation and lively return, factors that support long term aesthetic value.

Acquiring this specific specimen through The Natural Gemstone Company is therefore an acquisition of both a finely executed product and a durable, collectible natural mineral. The stone s dimensions and proportions make it adaptable to multiple settings, such as a classic four prong or bezel for secure daily wear, a low profile rubover for modern silhouettes, or a halo mounting that amplifies apparent size while juxtaposing the spinel s saturated pink against accent diamonds. For investors and connoisseurs who prioritize original state and craftsmanship, the absence of enhancement and the controlled polish and symmetry provide confidence in the stone s authenticity and future desirability. Routine care is straightforward, limited to gentle cleaning with warm soapy water and a soft brush to maintain brilliance, and we recommend documentation with a gemological report to accompany provenance and clarity notes.
