Digging for gems can be a profitable pastime, especially if you are a gem and mineral enthusiast. There are rock hunting and dig sites all over the United States that are open at different times of the year. Most digging sites consist of dump piles that are brought up from privately claimed mines, but occasionally private mining companies will allow you to excavate dig sites on their land. Always contact the owners of the dig site in advance, so you know what the current fees are and what equipment to bring for digging.
