Angelite

Angelite, also known as blue Anhydrite, is an anhydrous calcium sulfate appearing in compact masses or granular aggregates of pale blue color, often with white veins. It forms in arid environments through evaporation of sulfate-rich waters, primarily found in Mexico, Peru, and Poland. Historically associated with angelic communication and protection since ancient Egyptian times, who used it to carve amulets. Its delicate nature and water solubility make it a stone linked more to the etheric element than dense matter.
