As one of the most abundant crystals on Earth, Quartz is known as the "King of Crystals" and a "Master Healer." It is highly programmable with your intentions and not incidentally the prime component in electronics that now run our world. So use Quartz as your starting point to direct energy to where it will do the most good in life, whether it is for health, for healing, or for manifesting your heart's desires. Although Quartz often looks like ice, it is truly capable of starting real or virtual fires with a laser-like focus, so use it carefully with well-thought-out intentions.
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.
