Is it true that marble is more expensive than granite?

Quick question - what is the price difference between marble and granite slabs?  
Thank you!

Just as there are inexpensive and high-priced granites, the same goes for marble. It is the supply and demand (rarity) of the stone that dictates the price; so while the more easily sourced stones are less expensive, the stones more difficult to source will be more pricy.
