0.37 Ct. Tsavorite Garnet from Tanzania

This listing from The Natural Gemstone Company presents a single transparent green tsavorite garnet, round shape, 0.37 carat, dimensions 4.47 x 4.55 x 2.92 mm. The gem has been faceted to a mixed brilliant standard, combining a brilliant style crown with a carefully proportioned pavilion, and it exhibits an excellent polish across all facets. Clarity is graded included when evaluated at eye level, meaning that natural internal features are present but do not overwhelm the visual presentation, and the stone shows no enhancements. Origin is Tanzania, a well documented source for high quality tsavorite material, and the combination of intense color intensity and tight faceting yields strong visual saturation and lively light return for its size.

The cutting style is a mixed brilliant, with a table and crown geometry intended to maximize fire and return, while the pavilion facet angles have been calibrated to the tsavorites optical properties to optimize scintillation. The crown displays star and kite facets that feed light to the table, while the pavilion facets terminate in a pointed culet region that supports depth and contrast. Facet junctions are crisp, and the excellent polish minimizes surface diffusion so that the stone reads clean and vibrant even with included internal features. The included clarity characteristics are typical of tsavorites, often consisting of fine crystal inclusions or featherlike growth structures, and in this specimen they contribute subtle character rather than significant light obstruction. Precision cutting and consistent facet symmetry allow this gem to present as well centered, with balanced patterning when viewed both face up and in profile.

Color is a primary attribute for tsavorite garnet, and this stone displays an intense green with strong saturation and medium to slightly deep tone that remains lively under a range of lighting conditions. The hue sits squarely in the green spectrum, without strong yellow or blue modifiers, yielding a pure, verdant appearance well suited to classic solitaire and halo mounting styles. From a gemological standpoint tsavorite is a grossular garnet with refractive index approximately 1.740 to 1.760, it is optically isotropic as are all garnets, and it has a specific gravity in the vicinity of 3.60 to 3.68 which assists in distinguishing it from other green gem species. Dispersion is modest compared to diamond, which supports a cleaner green without excessive spectral flashes, and the excellent polish enhances surface brilliance while maintaining strong color saturation.

On the Mohs scale tsavorite garnet rates about 7.0 to 7.5, providing good general durability for daily wear, while remaining softer than corundum which rates 9 and well below diamond which rates 10. Compared to quartz at about 7.0, tsavorite offers similar resistance to scratching, and it is less prone to cleavage related breakage than materials such as emerald, which although similar in hardness can be more brittle due to inclusions and cleavage. For practical use this means a tsavorite of this size and cut is suitable for rings, pendants, and earrings when set with protective settings and reasonable care, and it will tolerate normal wear while avoiding sharp knocks and sustained impacts. The Natural Gemstone Company recommends secure channel or bezel settings for everyday pieces, periodic professional cleaning to maintain polish, and avoidance of ultrasonic treatment given natural inclusions and the absence of enhancements.

This tsavorite garnet, 0.37 carat, mixed brilliant round, Tanzanian origin, no enhancement, represents a finely executed small gem that combines intense color, precise cutting, and responsible sourcing. The balance of measurements 4.47 x 4.55 x 2.92 mm indicates efficient yield from rough material, and the craftsmanship is evident in facet alignment and surface finish. For buyers seeking a vividly colored green that performs well in jewelry, and for designers who prioritize natural material with clear provenance, this gem offers a compact yet impactful option. The Natural Gemstone Company stands behind the description and is available to provide additional photographic angles, mounting recommendations, and documentation to support secure purchase and integration into finished jewelry.
