1.70 Ct. Tsavorite Garnet from Tanzania

This transparent 1.70 carat cushion shape green tsavorite garnet presents precise proportions and a vivid, intense chroma, it measures 7.28 x 6.07 x 4.66 mm, and the length to width ratio of approximately 1.20 yields a slightly elongated cushion outline that is both elegant and highly practical for a variety of mounting styles. The cutting style is faceted with a mixed brilliant configuration, the pavilion and crown geometry have been optimized to capitalize on the optical properties intrinsic to garnet species, and the result is a stone that reads with concentrated green saturation and lively internal reflections. Clarity is graded as slightly included when evaluated at eye level, the inclusions are small and well positioned so they do not create disruptive windows or large dead zones, and the finish is an excellent polish that allows the true saturation and transparency to be read cleanly through the table. The stone is free of enhancements, originating in Tanzania, and it is presented by The Natural Gemstone Company with full disclosure of origin and treatment status.

The geometric faceting strategy employed in this cushion mixed brilliant is focused on maximizing light play through a controlled balance of facet size, orientation, and junction quality, the crown displays an array of modified brilliant facets including a restrained table facet, kite and star facets, and a series of well proportioned bezel facets that break incoming light into numerous scintillating return paths. On the pavilion the cutter has combined broader pavilion mains with precise lower girdle and pavilion facet planes that act as internal mirrors, this interplay produces a dynamic mix of brightness and contrast that elevates both scintillation and the perception of depth. The mixed brilliant approach leverages brilliant style geometry on the crown to enhance point scintillation, while employing step influenced planes on the pavilion to create face up color saturation and stable light return, the net effect is a gem that disperses light in small, crisp flashes, yet maintains a strong, uniform field of intense green across the table. Facet symmetry is tight, facet junctions are crisp, and the excellent polish minimizes surface diffusion so that light enters and exits the gem with minimal scattering, this geometric discipline is what produces the sense of motion and fire that knowledgeable buyers look for in higher end tsavorite specimens.

From a practical gemological perspective this tsavorite benefits from its combination of optical structure and cutting philosophy, the inherent high refractive properties of garnet families mean that appropriately set pavilion angles will yield efficient internal reflection and minimize light leakage, the cutter has targeted those angles to optimize return rather than solely maximizing carat retention, and as a result the stone maintains lively brilliance despite its deep, intense color. The slightly included clarity grade indicates the presence of natural features that confirm origin and authenticity, these inclusions are not intrusive to face up appearance and in many cases they serve as identifiers of natural formation, because no treatments have been applied the color and structure are entirely natural, and the excellent polish protects the surface from premature wear while enhancing visual performance. This 1.70 carat cushion tsavorite is extremely well suited to a range of settings from protective bezel mounts to refined four prong constructions that allow maximum light exposure, The Natural Gemstone Company can advise on ideal mounting proportions to maintain both security and optical performance, and we can provide additional images and magnified views upon request for in depth inspection.
