Many people assume that geodes might be present in Rhode Island. Although no instances of finding geodes were located here, it shouldn’t be ruled out as impossible. Geodes tend to appear near limestone, and Rhode Island has a couple of regions where it is present.

Agates, on the other hand, are much easier to find on Rhode Island. If you are in Providence, you can find agates in the area gravels, and quarries to the west. Beautiful green and red agates can be found at Mt. Hope Bay, in the surrounding beach gravels.

The area of gravels and quarries near Cumberland Hill is another excellent place to find agates in Rhode Island. You can also try your luck at the area beach gravels in Pawtuxet.

Staurolite rocks are found in Rhode Island as well. They are beautiful and usually rare, but you might be able to find some specimens at Jamestown Bridge, at the base near Jamestown.

Rhode Island is poor when it comes to gemstones. Some gemstones you can find are amethyst, bowenite (serpentine), amazonite, jasper (mostly pebbles), carnelian, olivine, rhodonite, and pyrite, or tourmaline among a couple of others. Some of the best places to find gemstones were the Diamond Hill and Iron Hill Mine, but they were closed.

Amethyst is among the few gemstones worth searching for in Rhode Island. It can be found in a variety of places. For example, you can find amethyst in Johnston, at the cliffs at 295 and Rte 6. Mt.

Hope Bay is the best place to find amethyst though, in the surrounding beach gravels. You can also search the beach gravels around Pawtucket for Amethyst.

If you want to find jasper in Rhode Island, you can go to Providence, and search the area gravels and quarries on the western side.

The area gravels and pits near Bristol are also excellent for searching for jasper, but mostly pebble specimens. Cumberland Hill though provides some bigger jasper specimens. Search for it in the area of gravels and quarries.

Finding a carnelian in Rhode Island is though. Carnelian pebbles are often found in Warwick, on the gravels around the shore. The gravel beaches around Mt. Hope Bay though, provide larger specimens. You can also find a carnelian at Pawtuxet, in the area of beach gravels.
