The microstructure of an uvarovite sample was analyzed using SEM methods. Tiny quartz and chromite inclusions, calcite filling in microfractures and grossularite that forms a solid solution with uvarovite were discovered in the sample. This demonstrates that the uvarovite of eastern Tibet is of skarn origin. The spectral characteristics of the uvarovite were investigated using UV-VIS absorption spectrometry.
