Marble is formed from Limestone, by additional heat and the earths crust forces. This process is called re-crystallization. The variety, textures and makeup of the marble is the result of the differences in the original carbonate minerals, the impurities, and the heat forces during this process.
Marble that comes from the purest calcite is usually white. Marble containing limestone is yellow or cream, if it contains serpentine then its green, if it contains hematite it is red. Marble is ageless and always remains contemporary. It has been used for thousands of years for its beauty, strength and resistance to fire and erosion.
The ancient Persians, Romans and Greeks used marble in many buildings and statues. To date, even with the advancements in technology, no one has been able to imitate the natural beauty of marble while maintaining characteristics of the real thing.
