1.63 Ct. Tsavorite Garnet from Tanzania

This oval 1.63 carat tsavorite garnet presents a carefully measured profile, with dimensions of 8.35 x 6.11 x 3.87 mm and a length to width ratio of 1.37, proportions that are highly desirable for engagement ring designs that aim to elongate the finger while maintaining a balanced face up appearance. The gem is executed in a mixed brilliant cut, combining a well faceted brilliant crown that maximizes scintillation with a controlled pavilion architecture that returns light to the observer while preserving color saturation. The overall depth measures 3.87 mm relative to the average diameter of 7.23 mm, producing a depth of approximately 53.5 percent which contributes to a lively interplay between brilliance and body color. Clarity is graded as slightly included at eye level, meaning there are small, naturally occurring internal features that are visible under close inspection but do not materially diminish the gem s transparency or its ability to scintillate, and the excellent polish ensures that facet junctions are clean and light transmission is unobstructed.

Color is a central attribute of this tsavorite, described as medium intense green with fresh green hues that are distinctly characteristic of high quality grossular garnet from Tanzania. The saturation sits in a range that reads as vivid under daylight, while the medium intensity allows the stone to maintain versatility in different mounting metals and lighting environments. Because this stone is unenhanced and natural, the color is intrinsic, consistent with the geological conditions of its Tanzanian origin. From a gemological standpoint tsavorite offers a favorable combination of optical properties, with a refractive index and specific gravity that contribute to strong internal light return and a notable presence on the hand, and a Mohs hardness in the vicinity of 7 to 7.5 that provides a sound balance between everyday wearability and the need for sensible care. Given the slightly included clarity grade, faceting was intentionally balanced to maximize both transparency and color, with controlled crown angles to produce lively facet reflections while minimizing windowing in the pavilion.

As an engagement ring option this tsavorite is exceptionally compelling for a client seeking a colored gemstone alternative to traditional diamond settings, particularly when the design intent is to emphasize color and optical performance. The oval outline and mixed brilliant faceting make it ideally suited to single stone solitaires with delicate tapered shoulders, to halo settings where melee diamonds intensify perceived brilliance and focal size, or to low profile bezel or semi bezel mounts that provide protection to the girdle area while showcasing the pavilion s depth and color. Practical setting suggestions include a four or six prong cathedral or half bezel for security and finger elongation, or an east west orientation for a modern aesthetic that leverages the 1.37 ratio. Maintenance recommendations for longevity are straightforward, regular inspection of settings to secure the stone, gentle cleaning with warm soapy water and a soft brush to preserve the excellent polish, and avoidance of harsh chemicals or prolonged heat to protect the untreated natural material. For clients who prioritize both optical quality and provenance, the no enhancement statement and Tanzanian origin provide clear documentation of natural properties and ethical traceability.
