Rockhounding Tip: Knowing state rocks, gemstones, minerals, fossils, and dinosaurs often can be very useful information for rockhounders.
Ordinarily, states with significant mineral deposits, valuable gemstones, fossils, or unusual or significant rock occurrences will designate an official state mineral, rock/stone, gemstone, fossil, or dinosaur to promote interest in the state’s natural resources, history, tourism, etc.
Accordingly, such state symbols often are a valuable clue as to potential worthwhile rockhounding opportunities.
Tennessee designated calcium carbonate, commonly known as limestone, as its official state rock in 1979.
