Purple

Most people use purple stones for calm, for bedtime routines, or as a focus for meditation. Amethyst on a nightstand and Lepidolite in a pocket are two easy ways to start. Both are gentle first stones.

Amethyst is known more for calm than for luck. In ancient Greece, people wore it to keep a clear head. If luck is what you're after, pair it with Citrine or Green Aventurine, the stones most tied to it.

Amethyst is the traditional pick. It has long been seen as a protective stone, especially for your mind and your sleep. Wear it as a bracelet during the day, or keep a cluster close to your bed at night.

Amethyst is February's birthstone, so it suits both Aquarius and Pisces born that month. Many zodiac guides link it with Pisces in particular. It's an easy birthday gift for either sign.

Most aren't. Amethyst is a common form of quartz, which keeps it affordable. A few purple stones are rare, though. Charoite comes only from Russia, and fine Tanzanite comes from one small area in Tanzania.
