2.60 Ct. Pinkish Purple Spinel from Tanzania

This offering is a transparent 2.60 carat cushion shape spinel, calibrated at 8.95 x 6.68 x 4.86 mm, presenting a pinkish purple hue with intense color saturation. The gem is cut to a mixed brilliant facet scheme that combines the scintillation of brilliant facets on the crown with carefully proportioned pavilion facets that manage color concentration and light return. Clarity is graded as very slightly included when evaluated at eye level, meaning inclusions are minimal, stable, and positioned such that they do not appreciably interrupt overall light performance. The polish is excellent, producing sharp facet junctions and lively surface reflectivity. There has been no enhancement to this stone, the color and clarity are natural, and the origin is Tanzania, which is known for yielding intensely colored spinel material. This combination of size, shape, and untreated intense color makes the gem well suited to fine bespoke work where natural color and technical cut quality are priorities.

From a gemological and lapidary perspective the mixed brilliant approach on this cushion is intended to balance two objectives, preserving color intensity while maximizing scintillation and dispersion. The crown retains a series of brilliant style facets that break large flashes into numerous small scintillation facets, enhancing visual activity under varied lighting. The pavilion facet architecture is modified to complement the crown, employing larger facets and controlled pavilion angles to direct light back through the crown in a manner that preserves the saturated pinkish purple without producing excessive windowing or dark areas. The facet junctions are precisely executed, the girdle is even, and the culet is calibrated to avoid a distracting opening in the pavilion. The measured depth of 4.86 mm yields a depth proportion appropriate to the cushion outline, approximately 62.2 percent when referenced against the average of the length and width, a proportion that supports balanced brilliance and face up color. The optical result is a lively, evenly colored stone that exhibits stable hue across viewing angles, which is characteristic of high quality spinel when well cut.

This spinel has been prepared for flexible integration into a wide variety of jewelry settings, and the dimensions and cut lend themselves to several design strategies. For a ring center a four or six prong setting with V style prongs positioned at the corners will secure the cushion outline while allowing maximum light entry through the pavilion, and an open gallery or pierced seat can be specified to increase backlight for a brighter face up appearance. A halo arrangement with micro pavé diamonds will increase the perceived size and further intensify the pinkish purple tone by contrast, while a three stone layout with tapered baguettes or trillion side stones will emphasize length and create classical proportions. For active wear a full bezel with a stepped inner lip provides protective security and a smooth silhouette, while a low profile bezel with a thin bezel wall preserves more of the stone surface for optical interaction. For pendants and earrings the stone sits well in a suspended prong basket that permits rotation and movement, enhancing scintillation, and in stud earrings a secure four prong or closed cup setting will balance protection with optical performance. East west orientations and asymmetrical settings are also effective with the cushion outline, enabling modern design vocabulary while maintaining stable seat geometry.

When planning custom work with this spinel consider metal choices, accent stones, and mounting tolerances in technical terms. Platinum or 18 karat white gold will provide a neutral contrast that highlights the cool pinkish purple tone, and near colorless melee diamonds in the G H color range and VS SI clarity range are a conventional match to create a luminous halo without distracting warmth. For stronger color contrast and a warmer presentation 18 karat yellow or rose gold will shift the perceived tone subtly toward pink, which many designers value for romantic palettes. Because the stone is untreated, every adjustment of metal color has a predictable effect on perceived hue. Seat design should accommodate the cushion proportions with a comfortable bezel or prong seat depth aligned to the pavilion apex, and experienced setters will prepare a culet supported seat or a minimally intrusive culet relief depending on whether the design prioritizes ease of cleaning or maximum light return. The Natural Gemstone Company provides consultation on prong count, prong profile, bezel wall thickness, and recommended gallery height to ensure the setting protects the stone while optimizing optical performance. We can also produce CAD visualizations and fabrication specifications for jewellers seeking exact tolerances, including suggested prong wire gauges, bezel radii, and mounting block dimensions for this 8.95 x 6.68 x 4.86 mm cushion spinel.

Provenance, treatment status, and craftsmanship are core considerations for collectors and designers alike, and this spinel is presented with transparent disclosure. Origin is Tanzania, enhancement is none, and the cut and polish quality have been executed to industry leading standards to preserve natural color and structural integrity. When integrating into a finished piece, routine care recommendations include avoiding sudden thermal shock and abrasive contacts, cleaning with warm water, mild detergent, and a soft brush, and avoiding prolonged exposure to harsh chemical cleaners. The Natural Gemstone Company stands ready to advise on setting construction, including torque specifications for prongs, soldering temperature guidelines to protect the stone during fabrication, and recommended insurance replacement values based on current market metrics for untreated spinel of this color and cut. For commissions we offer bespoke design collaboration, technical mounting drawings, and coordination with master setters to ensure the final piece realizes the inherent optical and material qualities of this 2.60 carat cushion spinel.
