Top Spots For Gem Hunting In The US


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, there are plenty of gem hunting spots in the United States where you can find these and many other stones. Most of these sites are not 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’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. So far, visitors to the park have found well over 30,000 diamonds, including a 16-carat beauty in 1975, so your chances of landing a stone are high. As with other diamond deposits, most of the stones are small and included, but some fine gems have been found here.

(UPDATE: In June, 2015, an 8.52-carat diamond was discovered at Crater of Diamonds State Park.  With an estimated value of $1 million, it’s the most valuable diamond ever mined in the US.  Read more about this unique diamond named Esperanza).
