1.77 Ct. Tsavorite Garnet from Tanzania

This transparent 1.77 carat cushion shaped tsavorite garnet from Tanzania presents a rare combination of intense chroma and excellent finish, making it an exceptional choice for precision setting by discerning clients of The Natural Gemstone Company. The gem measures 6.90 millimeters, 6.85 millimeters, and 4.90 millimeters across length, width, and depth respectively, yielding a depth ratio of approximately 71.3 percent when the average crown diameter is taken into account. The cutter has employed a mixed brilliant strategy, combining a faceted brilliant style crown with a pavilion that balances larger step influenced facets and modified brilliants to optimize both scintillation and color saturation. The table is proportioned to favor light entry and internal reflection, allowing the tsavorite to display its intense green across a range of viewing angles. Clarity is graded as slightly included when evaluated at eye level, with minor natural inclusions that do not materially interrupt light return or compromise durability. The polish is excellent, and the gem is unenhanced, providing assurance of natural color and structural integrity.

From a faceting and performance perspective the mixed brilliant approach in a cushion outline enhances the stone s apparent color saturation by creating overlapping flashes of green and deepening tones in the pavilion facets. The crown faceting pattern is tight enough to produce numerous small scintillation points, while the pavilion arrangement emphasizes depth of tone and contrast, resulting in a lively yet substantial visual weight beyond what the carat alone conveys. The slightly deep profile moderates crown height, producing a strong windowing resistance and preserving color under less than ideal lighting. Slightly included clarity at eye level typically indicates small crystal or feather inclusions that are internal, stable, and well positioned below the girdle or toward the pavilion in this specimen, thus maintaining clean table appearance and uninterrupted brilliance. Because the gem is untreated, its intense green derives from its native vanadium and chromium balance, meaning color response will remain stable under normal wear and when mounted.

When designing a custom mounting for this tsavorite consider metal choice and structural head design to both protect the stone and maximize optical performance. Platinum or 18 karat white gold will enhance the perceived green by providing a neutral reflective field, ideal when the objective is to emphasize saturation and brilliance. Conversely 18 karat yellow gold will introduce a warm foil effect that can intensify green perceived depth and create a vintage character. Given the depth ratio the setting must be engineered to accommodate the slightly deep pavilion without unduly raising the profile, therefore a low gallery prong head with a slight undercut or a fitted collet can secure the gem while preserving open pavilion access for light. A well executed prong design using four or six hands will expose sufficient crown for optimal sparkle while protecting corners typical of a cushion shape, or a partial bezel can be applied for a modern protective treatment without muting scintillation. The excellent polish ensures smooth reflective facets, so minimal ultrasonic exposure is recommended during post mount finishing.

For complementary gemstones in a custom piece the tsavorite s intense green responds exceptionally well to both neutral and contrasting accents, allowing versatile design directions. A halo of fine white melee diamonds with clean white color grades will enhance brilliance and create a high contrast perimeter that visually enlarges the central stone. For color contrast consider paired side stones in Ceylon blue sapphires to produce a classical green blue dialogue, or small vivid pink spinels or rubies for a saturated complementary scheme that accentuates the green through chromatic opposition. For linear flanking arrangements tapered baguette diamonds or step cut sapphires will echo the cushion s pavilion geometry and lend architectural harmony, while trillion or kite shaped sapphires set at shoulder angles provide dynamic color points without overwhelming the primary green. When arranging mixed colors maintain consistent refractive index planning by choosing accents with controlled brilliance to avoid overpowering the tsavorite s mixed cut optic. The Natural Gemstone Company can facilitate exact matching of size, hue and clarity for side stones, and will advise on prong geometry, girdle clearance and bezel tolerances to ensure that the finished piece balances protection, optical performance and intended aesthetic.
