The natural color of this variety of Garnet is orange through to red. Due to the addition of iron many stones can be orange-brown or reddish-orange. The darker red stones are thought to be a mixture of this variety with Almandine Garnet, which is a quite dark red. Orange or Mandarine ...

The lattice parameters of natural spessartine and uvarovite garnets were measured as a function of pressure up to 25 and 35 GPa, respectively, by synchrotron radiation powder diffraction. The bulk modulus and its first and second derivatives were determi
Using the calorimetrically determined S o and the C p polynomial for spessartine, together with high P– T experimental phase-equilibrium data on Mn 2+–Mg partitioning between garnet and olivine, allows calculation of the standard enthalpy of formation of spessartine. This gives Δ H f , Sps...
The lattice parameters of natural spessartine and uvarovite garnets were measured as a function of pressure up to 25 and 35 GPa, respectively, by synchrotron radiation powder diffraction. The bulk modulus and its first and second derivatives were determined by fitting three equation of state (EoS...
Using the calorimetrically determined So and the Cp polynomial for spessartine, together with high P–T experimental phase-equilibrium data on Mn2+–Mg partitioning between garnet and olivine, allows calculation of the standard enthalpy of formation of spessartine. This gives Δ H f , Sps o = -...
