Rock Shop of Earthly delights from jewelry, crystals, minerals, fossils, chakra, reiki & feng shui s We are a Rock Shop and more

Third Rock Emporium is a Rock Shop offering a variety, perhaps a plethora and possibly even a cornucopia of Earthly Delights including rocks, minerals, fossils, Handmade Native American Jewelry, Handcrafted Local Artisan Jewelry,Gemstones, Wood/Stone Carvings, Polished Stones, Crystals, Spheres, Pyramids, Chakra, Reiki & Feng Shui Supplies and much much more. After thirty years of rock peddling from town to town at fairs, festivals and flea markets as Mark's Rocks, I have decided that rocks are way too heavy to carry and that I needed a permanent Rock Shop location. Following a three month search and much consideration I'm thrilled to say our Rock Shop is located at 75 Main Street East Greenwich Rhode Island, next to The Greenwich Odeum and across from the municipal parking lot. We also carry an assortment of antiques and oddities so please stop in for a unique shopping experience that we hope you will enjoy.

Good Morning!

It’s going to be a good week too with nice weather and the Sip & Shop on Saturday from noon to five! Word on the street is that the Third Rock Fossils might be crawling in for a set!

The shoulder season between summer and the holidays is an important time to support small businesses. Maybe it’s time for a visit to Main Street.
