1.33 Ct. Tsavorite Garnet from East Africa

One transparent 1.33 carat oval green tsavorite garnet is presented with dimensions 7.89 x 6.42 x 3.53 mm, a mixed brilliant cut, and a clarity grade described as very very slightly included when evaluated at eye level. The gem exhibits intense color intensity and an excellent polish, with no enhancement reported, and an East Africa origin documented. The proportions of the oval and the mixed brilliant pavilion and crown produce an even light return and a lively faceted pattern. The stone is sufficiently deep to show saturated color yet balanced to avoid appearing overly dark when viewed in standard jewelry settings. The clarity assessment at eye level confirms a clean face up appearance, with inclusions noted only under magnification in typical gemological inspection, consistent with high quality tsavorite material.

The hue is a vivid pure green leaning slightly toward the cooler side of the green spectrum, with secondary notes of a fresh grass green at the face and a deeper forest green in the pavilion reflections. The tone ranges from medium to slightly dark, which contributes to the gem presenting strong saturation without appearing blackish in lower light. The mixed brilliant cut enhances scintillation and contributes to the perception of depth in the stone, with well executed facet junctions that support the excellent polish observation. Color zoning is minimal, and the green color reads uniformly across the table under daylight equivalent lighting, allowing the lively green to remain consistent from table to girdle. The gem's optical performance is characterized by bright flashes of green and occasional near colorless highlights from facet reflections, giving the stone a dynamic visual presence that remains elegant and refined.

When compared to Colombian emeralds from the Muzo and Chivor districts, this tsavorite differs in hue and tone by presenting a cleaner, more vivid green with less overt bluish undertone. Colombian emeralds often display a slightly bluish or teal hue and a varying degree of included character that can impart a softer visual texture, whereas this tsavorite is more transparent and delivers a direct, intense green without that blue bias. Compared to Zambian emeralds, which are frequently deeper and cooler in tone, this tsavorite appears brighter and more saturated in the mid to upper tone range, and it exhibits greater brilliance due to the garnet crystal structure and cutting style. In relation to Russian demantoid garnets, which are known for their yellowish green to olive green range and exceptional fire, this tsavorite holds a purer green hue with stronger saturation and less of the yellow component, producing a cleaner green appearance rather than the warm green tones associated with demantoid material. These comparisons provide a contextual understanding of how this East African tsavorite sits among well known green gemstones from historically significant localities.

Within the regional context of East African tsavorite sources, material from the Tsavo region in Kenya and from select Tanzanian deposits can vary subtly in hue and tone. Kenyan Tsavo tsavorites are often described as intensely saturated, vivid green with lively brightness, similar to the characteristics of this gem, while some Tanzanian finds may show slightly deeper tone or more pronounced secondary hues under certain lighting. This particular stone aligns closely with the classic Tsavo profile, offering a vibrant pure green and a medium to medium dark tone that facilitates strong color saturation. Compared to chrome tourmalines from Tanzania, which can show a darker, more camouflaged green with chrome richness, this tsavorite is generally lighter and clearer in appearance, with higher brilliance and less of the inky depth that chrome tourmaline can possess. When set against peridots from Pakistan and Myanmar, which tend to present a yellowish green hue and lower overall saturation, the tsavorite is markedly cooler in hue and significantly more saturated, reflecting its garnet chemistry and chromium and vanadium trace elements that yield the distinctive vivid green.

The Natural Gemstone Company documents this gem as natural, with no treatments recorded, and supports its provenance from East Africa. For settings and design considerations, the 7.89 x 6.42 x 3.53 mm oval cut will work well as a focal center stone in classic solitaire rings, halo settings, and bespoke pieces that value color purity and brilliance. The mixed brilliant cut maximizes scintillation while maintaining a stable profile for secure mounting, and the excellent polish will contribute to sustained brilliance in daily wear. The balance of intense color, transparent clarity at eye level, and precise cutting make this tsavorite a material suitable for collectors and designers seeking an unmistakable green that carries both gemological merit and aesthetic versatility. The Natural Gemstone Company includes standard gemological documentation on request, and the combination of provenance, no enhancement, and measurable gem metrics provides a clear basis for appraisal and design planning.
