1.84 Ct. Spinel from Tanzania

This exquisite purplish pink spinel from Tanzania weighs 1.84 carat, and presents in a classical emerald cut with precise dimensions of 6.81 by 5.91 by 5.05 millimeters, offered by The Natural Gemstone Company. The stone is transparent with a clarity grade described as very very slightly included when evaluated at eye level, which in practice means the gem is effectively eye clean and retains maximum visual purity in everyday wear. Color is described as medium intense, a balanced admixture of pink and subtle purple overtones that offers strong face up appeal without overwhelming the stone with saturation. The gemstone is natural and untreated, no enhancement, and it has been finished to an excellent polish, which preserves crisp facet junctions and a silky surface luster that enhances both brilliance and color transmission. Provenance from Tanzania is noted for producing some of the most desirable spinel material, and this specimen exemplifies the combination of natural origin, careful cutting, and unaltered state that discerning collectors seek.

The emerald cut on this spinel is a technically disciplined step cut, featuring broad parallel facets on the crown and pavilion that create a stair like optical architecture, and truncated corners that reduce susceptibility to chipping while adding geometric elegance. The cutter prioritized a broad rectangular table to maximize face up color and to present the purplish pink hue in evenly distributed planes, rather than attempting to maximize scintillation as a brilliant style would. The depth of the stone relative to its average dimension is approximately seventy nine percent, a proportion chosen to preserve weight and to enhance saturation through depth, while maintaining a stable windowing behavior typical of fine step cuts. Facet symmetry is exacting, facet junctions meet cleanly, and the excellent polish allows for uninterrupted light passage through the crystal lattice, enabling an even, velvety color appearance and softly defined step reflections. This is a gem cut with intent, where the cutter deliberately balanced color retention and optical harmony, producing a stone that reads larger face up than its carat weight might suggest due to the efficient planar geometry of the emerald cut.

From a gemological perspective this spinel exhibits the classic physical and optical attributes that make spinel both beautiful and resilient. Spinel is a cubic mineral with a single refractive index, here approximately one point seven one eight, and a specific gravity near three point six zero, values that contribute to the gem having substantial heft and a lively but controlled light return. Hardness on the Mohs scale is eight, making this piece durable for daily wear, able to resist abrasion while taking a high polish that maintains its attractiveness over time. The purplish pink coloration is most commonly influenced by trace chromium in the crystal lattice, producing vivid pink to red hues, while additional trace elements and the trace balance of chromium to other constituents can shift the tone toward purple. Because the stone is untreated, its coloration is natural, stable, and not subject to the fading risks associated with some surface or diffusion treatments. Clarity is very very slightly included at eye level, and inclusions are minimal and isolated, requiring magnification to assess, which preserves both visual appeal and market desirability for collectors and investors who prioritize untreated material.

Owning this spinel is a purposeful investment in both beauty and craftsmanship, it combines natural rarity, considered cutting, and material integrity in a single piece that is suitable for a high end collection or for creation into a signature jewel. Unenhanced purplish pink spinel of this caliber and provenance is uncommon, and its value is supported by the stability of spinel as a gem species, the enduring desirability of fine natural color, and the market preference for well cut stones that show face up color and proportion. The lapidary decision to execute an emerald cut was intended to emphasize color saturation and consistent color zones, while preserving carat weight and structural strength, and such decisions translate into long term collector value because they maintain both aesthetic and physical resilience. At The Natural Gemstone Company we document origin and treatment status, and we can provide additional imagery, magnified detail plates, and certification on request, enabling buyers to assess the stone at the technical level they prefer. For the buyer who appreciates mineral chemistry, optical performance, and the meticulous hand of a cutter who values proportion and polish, this 1.84 carat purplish pink emerald cut spinel represents an investment in lasting beauty and refined craftsmanship.
