January’s birthstone, garnet, is known for its impressive variety of eye-catching colors, which can be almost any color of the rainbow. Garnets occur in green (demantoid and tsavorite), orange (spessartine), red (almandine and pyrope), and purplish red (rhodolite), plus a few rare garnets even change color under different types of light. But color is far from a garnet’s only attractive feature.
GIA’s Garnet Buying Guide offers key pointers on what quality factors to look for, and helps you differentiate between some of the garnet varieties, for example two of the green garnets: tsavorite and demantoid.
