The answer depends on your definition of ‘rock’. If you are talking about minerals, mineral specimens can be very valuable and certain minerals and stones are prized for jewelry. If you are talking about crushed rock, it is used for grading and filling on excavation sites and building sites. It is also used for landscaping. Delivery is typically done by the truckload or the ‘yard’.
