Does calcite have the function of feng shui regulation?

No, in geomantic omen, calcite ornaments can also improve the geomantic omen at home, save houses and gather wealth. But these are folk superstitions, which have no scientific explanation and have no effect on regulating Feng Shui. Calcite is similar to anhydrite, smooth as Bai Shiying, and widely distributed. It is an endogenetic hydrothermal vein and sedimentary carbonate rock.
