3.12 Ct. Rhodolite Garnet from Tanzania

This 3.12 carat oval purplish pink rhodolite garnet from Tanzania is a finely balanced example for the discerning collector and jeweler, with face up dimensions of 9.10 by 7.76 by 5.86 mm, a mixed brilliant cut, and an excellent polish. The clarity was evaluated as very slightly included, evaluated at eye level, and the color registers as intense, which together produce strong face up saturation and lively internal brilliance. The stone has undergone heat treatment, a common and stable enhancement in colored gemstones, disclosed here for full transparency. The purplish pink hue leans toward the classic rhodolite family profile, with a violet leaning pink that is deeper and more saturated than many Sri Lankan rhodolites, which often show a lighter, more pastel pink to lilac tone, and less prone to the raspberry red bias seen in some East African garnets. Compared to rubellite tourmalines from Brazil, which frequently exhibit a bright electric pink with more vivid fluorescence, this Tanzanian rhodolite displays a more restrained, velvety tone, offering depth rather than overt saturation. Compared to spinels from Myanmar and Sri Lanka, which can present a purer pink to red with exceptional brilliance, this garnet emphasizes a warm purplish cast and a different kind of optical richness derived from its higher refractive index and strong color zoning control.

For an educated buyer assessing value, this gem offers several compelling attributes, and The Natural Gemstone Company presents it with full provenance and treatment disclosure. The mixed brilliant cut maximizes return of light for this refractive index class, and the very slightly included clarity grade at eye level means the stone reads visually clean in most mounting styles, preserving both aesthetic appeal and marketability. The intense color intensity is particularly important for rhodolite pricing, as saturation and hue stability drive demand more than sheer carat weight in this species. Origins from Tanzania contribute to desirability, given the country’s reputation for producing high quality purplish pink rhodolites, and the heat treatment reported here is industry standard, applied to enhance color uniformity without undermining structural integrity. When compared to gemstones from other famous locations, this piece occupies a niche between the delicate pinks of Sri Lanka and the vivid rubellite tones of Brazil, making it a versatile and valuable choice for collectors and fine jewelry designers seeking a rich purplish pink garnet with excellent cutting and disclosure.
