Lepidolite is a pastel-colored mineral from the mica group. It grows in a stacked hexagonal formation, which led the stone to be nicknamed stone scales for the way the shapes stack on top of each other. It also grows in sheets, and when cleaved, they have a naturally glittery appearance. Lepidolite varies in coloring, but typically it comes in a pink or purple shade. Because lepidolite is colored with manganese, the typical coloring for lepidolite is similar to rhodonite-- another gemstone colored with manganese. Most lepidolite is a reddish-pink color, however, some rare forms of lepidolite can be soft pinks, and even rarer still, lavender and deep purple.The rarest forms of lepidolite are purple-grey, and colorless.
