Garnet is available in many colors including pink, black, blue, brown, purple, green, yellow, orange, red and colorless. Almandine, spessartine, grossular, uvarovite, andradite and pyrope are six minerals which are regarded as belonging to the garnet family. Pyrope is the only member of garnet group that displays a distinct red color in its natural samples. Almandine is the most common garnet and comes in wide range of colors including purple, wine red, purplish red, brown, and deep red among others.
