Marble is a metamorphic rock that forms when limestone is subjected to the heat and pressure of metamorphism. It is composed primarily of the mineral calcite (CaCO3) and usually contains other minerals, such as clay minerals, micas, quartz, pyrite, iron oxides, and graphite. Under the conditions of metamorphism, the calcite in the limestone recrystallizes to form a rock that is a mass of interlocking calcite crystals.
Marble is a beautiful and plentiful crystalline stone that is commonly found in USA, Italy and Greece. Every marble is unique like a snowflake and can be found in shades of white, yellow, green, brown, black and grey. The healing properties of Marble is used as a cleanser which is beneficial for the blood, skin and systems that help cleanse the body such as the lymphatic, digestive system and integumentary system. Metaphysically this stone is beneficial for clarity during tantric activities and meditative states. It aids strength of self control and mastery of thought. It improves total recall of dreams and provides protection, stability and structure of one’s physical, emotional and spiritual facets.
