There are some historicallyimportantkinds of marble, named after the locations of their quarries, include:
- Carrara (Italy)
- Pentelicus (Greece)

White marbles, like Carrara, have been prized for sculpture sinceclassical times. This preference has to do with the softness and relativeisotropy and homogeneity, and a relative resistance to shattering. Also, thelow index of refraction of calcite allows light to penetrate severalmillimeters into the stone before being scattered out, resulting in thecharacteristic “waxy” look which gives “life” to marblesculptures of the human body.
