When you think of mining for the "big four" gemstones — diamond, ruby, sapphire, and emerald — it's easy to imagine places like India, South Africa, and Colombia. However, you can find these stones and many others at plenty of gem hunting spots in the United States. Most of these sites aren't on the same scale economically as mines in other countries, but they make exciting gemology-themed vacation destinations for the lone prospector and the whole family alike.

You can mine all sorts of beautiful gemstones in the United States. This Montana sapphire made a wonderful engagement ring stone. Imagine finding your own treasure this summer through gem hunting. Watch your own gem take shape, from rough to faceted, then have it set in an amazing jewelry piece. Video by CustomMade. Used with permission.

Gem Hunting is a Great Vacation Idea

Crater of Diamonds State Park, Murfreesboro, Arkansas

Want to mine for diamonds? Murfreesboro is the place to go. The Crater of Diamonds State Park, 120 miles from Little Rock, AR, is the only existing mine where visitors can prospect for diamonds and keep their findings. Stay at the park campsite and enjoy wildlife and natural scenery as well as some sparkling stones.

You'll see diamonds everywhere, even laying in the dirt, but you can rent equipment at the park for deeper digging. Once you have a pan of stones, head over to the office so an appraiser can check your stash to see how much your sparklers are worth.
