The term "Marble" is derived from Latin word "Marmor" which itself comes from the Greek root "Marmaros" meaning thereby a shining stone. Technically marble is a recrystallised, compact variety of metamorphosed limestone capable of being polished. Commercially, marble is any crystalline rock composed predominantly of calcite, dolomite or serpentine having 3-4 hardness, which can be excavated as blocks and can be sawed and polished. Amongst the building stones, marble occupies a unique position. Since time immemorial, marble has been used in temples, mosques, palaces, monuments etc. as an ornamental and decorative stone because of its pleasing colours, attractive patterns and designs.
