Umbalite or Umba river garnet
A variety of garnet consisting of a mixture of pyrope, almandine, and spessartine garnet, having the chemical formula Mg₃Al₂(SiO₄)₃-Mn²⁺₃Al₂(SiO₄)₃, exclusively found in the alluvial deposits of the Umba River, and having a light-pink to purple colour.
Named for the Umba Valley of the Tanga Region of Tanzania, the location of the mineral’s first discovery in 1978: Umba + -lite
Garnets are nesosilicates having the general formula X3Y2(Si O4)3. The X site is usually occupied by divalent cations (Ca, Mg, Fe, Mn)2+ and the Y site by trivalent cations (Al, Fe, Cr)3+ in an octahedral/tetrahedral framework with [SiO4]4− occupying the tetrahedra.
Garnets are most often found in the dodecahedral crystal habit, but are also commonly found in the trapezohedron habit. They crystallize in the cubic system, having three axes that are all of equal length and perpendicular to each other. Garnets do not show cleavage, so when they fracture under stress, sharp irregular pieces are formed (conchoidal).
Umbalite garnet hardness
Because the chemical composition of garnet varies, the atomic bonds in some species are stronger than in others. As a result, this mineral group shows a range of hardness on the Mohs scale of about 6.5 to 7.5. The harder species like almandine are often used for abrasive purposes.

The calm and refreshing pink and purple hues make an excellent addition to this growing selection.
