One of the biggest portions of this Under $20 section is the wide variety of crystal tumbles and worry stones that are the perfect size to keep in your pocket or purse! Tumbled crystals are also great to use for crystal healing gridding, spells and moon rituals, or you can purchase a ton of different crystals if you are just wanting to get to know each crystal type or put together a crystals for beginners gift set. Although we do have one of those already too!
