Lepidolite vs. Amethyst — What's the Difference?

Difference Between Lepidolite and Amethyst


Key Differences

Lepidolite is a mineral belonging to the mica group and is primarily identified by its high lithium content and soft, layered structure. Whereas, amethyst is a variety of quartz that is characterized by its distinct purple coloration, which can range from light lavender to deep violet.
Lepidolite often exhibits a pearly luster and can appear in various shades from pink to purple, depending on its chemical composition. On the other hand, amethyst has a glassy luster and its purple color is typically uniform, which is caused by irradiation and iron impurities in the quartz.
In terms of hardness, lepidolite is quite soft, rating a 2.5 to 3 on the Mohs scale, which makes it susceptible to scratching and not ideal for jewelry that requires durability. Amethyst, however, is much harder, with a rating of 7 on the Mohs scale, making it suitable for various types of jewelry.
Lepidolite is often mined for its lithium content, which is used in the manufacture of batteries and mental health medications. Whereas amethyst has been highly valued throughout history both for its beauty and purported healing properties, which include stress relief and the promotion of clarity.
While lepidolite is typically found in granite pegmatites and is less commonly known in the gem world, amethyst is found in geodes and volcanic rocks and is one of the most popular and recognizable gemstones globally.
