1.50 Ct. Tsavorite Garnet from Tanzania

This transparent 1.50 carat trillion shape green tsavorite garnet from Tanzania presents with exacting dimensions of 7.25 x 6.82 x 5.04 mm, a classic trillion cut that emphasizes pavilion symmetry and crown facet geometry to maximize light return. The cutting style is executed in a brilliant oriented facet pattern which uses a dense array of triangular and kite facets to boost internal reflection and create uniform scintillation across the triangular profile. Clarity is graded slightly included, evaluated at eye level, and the inclusions are small, primarily fine needles and pinpoint crystals that do not obstruct transparency, allowing the stone to maintain strong window free light performance. Color intensity is described as intense, with a saturated pure green that is evenly distributed and free of zoning, and the polish is excellent, providing a glasslike finish that enhances facet contrast and directional reflectivity. No enhancement has been applied to this tsavorite, preserving its natural body color and optical properties, and the untreated origin of Tanzania is documented, which is consistent with high quality grossular garnet material from that region.

When comparing reflective qualities to other gemstones in its category, tsavorite occupies a distinctive optical niche. With a refractive index in the approximate range of 1.740 to 1.760, tsavorite returns more brilliance than classic green beryls such as emerald, which have lower refractive indices near 1.56 to 1.60 and therefore present a softer, deeper glow rather than sharp brilliance. Compared to demantoid garnet, which has a higher refractive index and notably higher dispersion, this tsavorite exhibits slightly less spectral fire but greater color purity and a cleaner, more saturated green. Against green sapphire, which has a similar refractive index near 1.76 and a firmer brilliance, the tsavorite offers a brighter perceived saturation because of its higher light scattering from the dense brilliant style cutting, producing vivid scintillation in smaller sizes. Spinel and peridot which have lower refractive indices and lower dispersion show reduced return of white light and less lively scintillation relative to this tsavorite. For the technical buyer who values precise faceting, intense natural color, minimal eye visible inclusions, and an untreated Tanzanian origin, this trillion cut 1.50 carat tsavorite from The Natural Gemstone Company delivers exceptional brilliance, clean color saturation, and reliable light performance suitable for settings that demand both optical impact and gemological integrity.
