Rock enthusiasts from across the Midwest make pilgrimages to this geological wonderland where you can literally dig through barrels of rough stones to uncover your own treasures.

The Gem Shop is a true lapidary, from the mining of fine agates and jaspers to the cutting of unique designer cabochons.

Established in 1971 by Eugene Mueller, who developed his passion for rocks as a young boy visiting his grandfather in Minnesota, this family-owned business has evolved from a basement operation into one of the most comprehensive rock shops in the region.

What sets this place apart from typical tourist rock shops is its hands-on approach to discovery.

You’ll find yourself digging through outdoor yards and basement areas filled with barrels and bins of various rock types. Many visitors spend hours carefully selecting pieces that catch their eye, whether you’re a serious collector or simply curious about the natural world.

The variety is overwhelming, making each visit feel like a genuine treasure hunt where you never know what geological wonders you might discover.

Underground Mining Experience: When winter weather covers the outdoor yard, the basement remains open with organized boxes and bins full of rock specimens. The basement creates an authentic mining atmosphere where you can choose from rows of neatly labeled containers filled with stones.

The hands-on experience often sparks new interests in geology and lapidary arts, with many visitors leaving with a newfound appreciation for earth sciences.

Massive Petrified Wood Display: The centerpiece attraction is an 8000-pound Arizona petrified wood log collected in 1910 from the Petrified Wood Forest area before it became a national park. This specimen stands about 6 feet tall and serves as a stunning photo opportunity that showcases the shop’s commitment to preserving geological history.

Best Times to Visit: The shop offers optimal experiences during warmer months when you can fully enjoy the outdoor rock yard activities. However, the basement remains active year-round, ensuring winter visits still provide substantial exploration opportunities.

Bringing Containers: Serious rock collectors often bring multiple containers or buckets to hold their discoveries, as the digging experience frequently yields substantial collections. Planning ahead with proper containers maximizes your treasure-hunting success.

Group Tours Available: The shop accommodates tours for rock clubs, school groups, and geology classes seeking educational experiences focused on lapidary arts and geological sciences.

I love writing and I love Minneapolis! My favorite places to explore are charming small towns, vibrant arts scene, and hidden gems anywhere outdoors. Fall foliage with a good documentary is my version of heaven.
