Metamorphosed Limestone (principally Calcium Carbonate, CaCO3)

Rock Type: metamorphic

Carrara Marble

Physical Properties

Hardness: 3 on Mohs scale; Color: White to blue-gray; Luster: Vitreous to pearly; Crystal structure: Trigonal/Hexagonal (granular); Cleavage: Perfect rhombohedral in calcite crystals; Specific Gravity: 2.7

Formation & Geological History

Formed from the regional metamorphism of limestone or dolostone under high pressure and temperature, often during mountain-building processes. The specific Carrara variety is found in the Apuan Alps of Italy.

Uses & Applications

Extensively used in sculpture, interior decoration, flooring, countertops, and luxury construction. Due to its calcium carbonate content, it is also used in pharmaceuticals and paper manufacturing.

Geological Facts

Michelangelo's David was carved from a single block of Carrara marble. It has been used since the time of Ancient Rome for iconic structures like the Pantheon and Trajan's Column.

Field Identification & Locations

Identified by its white-to-gray ground color with subtle, smoky grey veining. It feels cool to the touch and will effervesce (fizz) when exposed to a weak acid like vinegar or lemon juice.
