grossular garnet

Grossular garnet, a type of garnet, is the birthstone for January. They come in many colors, including colorless, gray, yellow, green, brown, and orange, and some have different names depending on their color. For example, green is called "tsavorite," orange is called "hessonite," and colorless is called "leucogarnet." Some of them fluoresce under ultraviolet light and some are bi-colored, making them fun to collect.
