Quartz that are harder and considerably more denser are more difficult and exspensive to quarry and process. Quarrying methods vary as well; stones may be quarried below ground, which is more exspensive than above ground. Also since natural stone is quarried all over the world, long distance shipping factors into the price.

The larger the stone, the more difficult it is to process, handle, pack, and transport. Larger sizes also tend to have a higher amount of waste compared to the part that is used, which makes them more expensive.

The availability of a particular stone is the most important factor in determining price. However, handling and transportation cost does drop slightly for a larger quantity. The best way to reduce cost is to find a stone dealer who is running a special on a particular product.
