Orange-red Spessartite crystal displaying textbook dodecahedral form typical of garnet group minerals. Rich in manganese and aluminum, Spessartite is prized for its fiery saturation and excellent refractive qualities. Its vibrant color results from the presence of manganese (Mn³⁺), and unlike many garnets, Spessartite rarely undergoes treatment—making specimens like this highly sought after in natural form.
The Loliondo region of northern Tanzania became internationally recognized in the mid-2000s after local miners discovered large, well-formed Spessartite crystals embedded in weathered granite. These finds quickly attracted attention for their combination of size, crystal habit, and intense coloration. Production peaked around 2007–2010, with much of the material entering the collector and lapidary markets. However, access to the region has since become restricted, and new production has dwindled, making older, high-quality pieces increasingly difficult to source.
This specimen represents a classic example from the peak of the Loliondo discovery, offering both mineralogical interest and collectible appeal.
