1.59 Ct. Tsavorite Garnet from Tanzania

This 1.59 carat oval tsavorite garnet presents as a transparent, well proportioned gemstone with dimensions of 7.88 by 6.36 by 4.15 millimeters, reflecting careful lapidary judgment in the transition from rough to finished stone. The cut is a mixed brilliant design, combining a brilliant style crown with a pavilion that retains modified facets to maximize return of spectral green light, and the measured depth relative to the average girdle diameter is approximately 58 percent, which contributes to a robust face up presence and lively internal return. The medium color intensity is an even, grass to forest green with good saturation across the table, and the excellent polish produces crisp facet junctions and bright facet windows that enhance both scintillation and overall brilliance. These optical attributes are consistent with a quality tsavorite that balances color and light performance, and the oval outline produces a flattering visual spread that translates well into both ring and pendant settings.

The gem has a clarity grade of included as evaluated at eye level, and the inclusions are typical of natural grossular garnets without evidence of clarity enhancement, which underscores the integrity of the material. Internal characteristics are visible on close inspection and contribute to the gemological fingerprint, while not significantly compromising transparency in standard jewelry use. There has been no enhancement applied to this tsavorite, it is unheated and untreated, and that natural state is important for collectors who value provenance and authenticity. Origin is Tanzania, and through The Natural Gemstone Company we maintain direct relationships with sourcing partners to ensure accountable supply chain practices, documentation of origin, and fair remuneration for artisanal mining communities wherever possible. For the conscious buyer who places importance on traceability, this tsavorite is presented with clear sourcing information and an emphasis on responsible procurement rather than anonymous bulk supply.

From a gemological perspective this tsavorite exhibits the expected physical properties of green grossular garnet, including a Mohs hardness in the range of 7 to 7.5 which provides reasonable everyday wearability when set with appropriate protection, and an isometric crystal habit that produces singly refractive optical behavior and strong, even color distribution. Typical refractive index values for tsavorite lie around 1.740 to 1.760 and a specific gravity in the mid threes, and those characteristics contribute to the stone feeling substantial for its dimensions. Practical considerations for setting include choosing a secure mounting that protects the girdle and corners, such as robust prong work or a bezel style for daily wear, while a well designed open gallery can maximize light entry for optimal brilliance. For the collector who seeks natural, untreated gemstones with documented origin, this 1.59 carat oval tsavorite offers a combination of technical refinement, honest clarity grading, and ethically minded sourcing, and it aligns with The Natural Gemstone Company commitment to responsible gem stewardship and to supplying stones that satisfy both connoisseurship and conscientious consumer standards.
