This is perhaps the most common decorative stone type of all times. It is formed naturally when limestone underground is heated and pressurised over the years, a process referred to as re crystallisation. These processes change the texture and the makeup of limestone resulting in impurities that change the mineral composition the limestone and therefore the colour.
Based on this, Marble containing hematite is reddish in colour, that containing limonite is yellow while that featuring serpentine is green in colour. Marble is fragile and less resistant to external factors and therefore may not be suitable for certain types of buildings. It is best for countertops, fireplace-housing elements, windowsills as well as steps and risers. Marble has always been highly valued for its beauty, strength, and resistance to fire and erosion.
