2.10 Ct. Pinkish Purple Spinel from Tanzania

This 2.10 carat oval spinel measures 8.26 by 7.08 by 5.03 millimeters, with a measured depth ratio of 65.6 percent, a mixed brilliant faceting style, and an intense color intensity. The gem is transparent, graded at very very slightly included when viewed at eye level, and it carries an excellent polish, with no enhancement reported. Origin is Tanzania, and the combination of weight, proportions, and polish produces a gemstone with immediate presence and robust optical performance. Technically, spinel has a refractive index near 1.718 and a hardness of approximately 8 on the Mohs scale. These physical properties inform both the cutting strategy and the practical wearability of the piece. The balance between table size and pavilion depth in this oval achieves a controlled amount of light leakage and color saturation, preserving strong return of light while maintaining the intense pinkish purple hue.

The mixed brilliant cut applied to this oval employs a brilliant facet pattern on the crown combined with stepped facets on the pavilion, a configuration chosen to enhance both scintillation and color saturation. On the crown, smaller kite and star facets surrounding a proportionally sized table create numerous angular returns that animate the pinkish purple hue under direct light. On the pavilion, broad step facets establish planar surfaces that concentrate and deepen the color, a deliberate tactic when working with stones that possess high inherent saturation. The cutter targeted pavilion angles in the low forties to optimize internal reflection for spinel at its refractive index, and the result is a stone that reads as lively in motion yet uniformly saturated at rest. Facet junctions are crisp, symmetry is tight for an oval profile, and the excellent polish minimizes surface diffusion, allowing the stone to present a clean window for internal color and clarity to be assessed.

Comparatively, the hue and tone of this Tanzanian pinkish purple spinel occupy a distinct position among notable gemstone localities. Against Mahenge Tanzanian pink spinels that are renowned for neon hot pink saturation, this stone leans slightly toward a cooler axis, with a discernible purple bias that tempers the pink, creating a pinkish purple hue rather than a straight vivid pink. Versus classic Mogok and other Myanmar spinels that often display a hotter red to raspberry pink hue, the Tanzanian example here is less red leaning and more balanced between pink and violet, providing a floral violet overtone that reads as sophisticated and slightly cooler in tone. When compared to Sri Lankan sapphires that present purplish sapphires with a softer, often lighter tone, this spinel is distinctly more saturated and more transparent, offering higher intensity at a comparable tone range. In relation to rubellite tourmalines from Brazil that push toward redder, deeper tones, the spinel remains lighter and clearer, with a tone that sits in the medium to medium dark range while retaining exceptional brilliance due to the mixed brilliant architecture.

The combined assessment of hue, tone, and craftsmanship frames practical recommendations for mounting and presentation. Because the color is intense and the stone is unenhanced, settings that allow ambient and transmitted light to interact with the pavilion will maintain maximum color depth and sparkle. Open halo or four or six prong settings that expose the girdle and pavilion with a secure seat are recommended to avoid deadening the color with overly deep bezels. For designers seeking to emphasize the purple aspect, pairing with cool white metals will emphasize the violet bias, while warm metals will subtly enrich the pink component. From an investment and rarity perspective, an unheated, Tanzanian origin spinel with very very slightly included clarity and excellent polish is highly desirable, given current market interest in natural, untreated colors.
