Quartz is both the second most abundant mineral in the Earth’s crust and, perhaps more relevant for our purposes, a large family of crystals. The word crystal comes from Greek for ice, because quartz was thought to be eternal ice sent by the gods. Until the late 1500s, scholars actually thought quartz was crystallized ice. Clear quartz is known as the “universal crystal.” Turn to quartz for all-purpose healing or to amplify the energies of other crystals. Seeking clarity? Quartz! Meditate deeply and manifest clearly with this energetic stone.
