Exceptional Umbalite Garnet – 3.96 Carats | Custom Faceted | Umba Valley, Tanzania
Offered is this striking 3.96 carat Umbalite garnet from the renowned Umba Valley region of Tanga, Tanzania, celebrated for producing some of the world’s most vivid pink-to-purple garnets. This 7.7 × 15.5 mm gem displays an intense raspberry-magenta hue with flashes of fuchsia and deep wine tones, exhibiting excellent saturation and lively internal brilliance. The color remains strong across lighting conditions, a hallmark of fine Umbalite material.
Expertly custom faceted by TheGemstoneMan LLC, this elongated, sculptural cut was designed to maximize color return and visual movement rather than conform to mass-market shapes. The result is a bold, modern gemstone with a distinctly artisanal presence—ideal for a one-of-a-kind jewelry design or discerning collector.
At nearly 4 carats, this stone represents a size that is increasingly uncommon in high-quality Umbalite garnet, especially with this level of color intensity and transparency. Garnets are naturally untreated, and this stone has received no enhancements.
