The "Queen of Crystals" Amethyst is an incredible stone that can be used in many ways. It rules the realm of mind and spirit, providing a protective light shield around one’s aura to guard against psychic attacks as well panic episodes or addiction-related conditions because it helps conquer these things with its calming purple color which calms emotions down so you don't feel anything negative when meditating.
Tumbled stones are smaller pieces of crystals or rocks that have been processed in a rock tumbler with water, sand, and grit. Over weeks in a tumbler, the stone edges and surfaces become smooth and sometimes highly polished to bring out the beauty of the stone. The pleasing shape and size of tumbled stones make them desirable as more inexpensive and usable crystals.
