1.72 Ct. Tsavorite Garnet from Tanzania

This 1.72 carat pear shape green tsavorite garnet presents precise proportions and a poised presence, measuring 7.50 x 7.32 x 4.35 mm. Cut in a mixed brilliant configuration, the facet design pairs a faceted crown optimized for scintillation with a pavilion geometry calibrated for strong light return, supporting an intense color intensity and an eye clean clarity grade as evaluated at eye level. The stone is transparent and unenhanced, with excellent polish across all facets, and originates from Tanzania. The Natural Gemstone Company offers this gem as an example of natural color and optical performance, with the green deriving from trace chromium and vanadium within the grossular garnet structure.

The tsavorite garnet’s structural and optical properties are central to its distinctive sparkle. As a member of the grossular garnet group the crystal lattice is tightly packed and isotropic, producing a relatively high refractive index, which narrows the critical angle and promotes efficient internal reflection. The consequence is a pronounced return of light to the viewer, yielding strong brilliance. Because garnets are isotropic and lack birefringence the light path is not split, resulting in crisp, well defined flashes rather than diffuse or doubled light, and the mixed brilliant cut further magnifies these effects by balancing small, precise crown facets that generate lively scintillation, with pavilion facets that facilitate controlled dispersion and return of light. The combination of intense saturation, eye clean clarity, and excellent polish ensures that light travels through unobstructed planes, maximizing both bright white flashes and subtle colored dispersion. The absence of any enhancement means the visible intensity and hue are inherent to the stone, a direct product of its chemical composition and crystalline order. Collectively these attributes produce a sparkle that is both vivid and defined, a characteristic that distinguishes this 1.72 carat pear shape tsavorite within a range of green gemstones.
