Gemologists separate the 6 gem Garnet species of the Garnet group into these two sub-groups or series. The 3 species in each ternary intermix with each other in what is termed a solid solution series. Ugrandite is an abbreviation for the Uvarovite-Grossular-Andradite solid solution series.onsequently, the chemical composition of a particular gem is not known by the average gemologist or student who wants to identify a Garnet by species or variety. Usually refractive index, color and absorption spectra are the only clues to Garnet identification.
