AME World of minerals ltd can offer various high quality marble in distinctive varieties and colours from Afghanistan and Pakistan. Marble is a metamorphosed limestone, consisting of very pure calcium carbonate. The different types of marble have densities between 2500 and 2800 kg / m3. Because of its beautiful, almost transparent light, solidity, relative isotropy and homogeneity, marble is very popular as a building material and in sculpture, although it is a rather hard stone for manual processing. The temperatures and pressures required to convert limestone into marble are so high that any fossils present in the limestone are destroyed.
