At the different quarry places, Lasa Marble is found in several grain sizes. The one in the Lasa Valley (Laaser Tal) is more fine grained, which makes it particularly valuable and precious. Compared to most of the commercially available marble types, the Lasa Marble shows an up to twenty percent increased hardness. The calcium carbonate content (CaCO3) for pure white Lasa Marble ranges between 96.4 and 98.6 percent. Lasa Marble is resistant to frost and de-icing salt. The good and even indentation of the crystals in the stone makes Lasa Marble water-impermeable.
