It is mostly used in interiors such as flooring units, interior walls. Marble with thickness of 3 or 4 is often used for interior stairs. The price of marble in international markets depends on 2 factors. First Natural property of marble and its appearance, second the quality of processed product. For this reason, two similar batches of stones might have different prices in two stores due to the difference in production and processing.
