Gem mining is a hit for kids and parents. In fact, many adults buy their own big bag because it’s such a fun surprise to see what’s inside!
STEP 1: Purchase a bag of mining rough.
STEP 2: Go outside to the running water sluice.
STEP 3: Get a wooden mining pan. Empty your mining rough in small sections, rinse it in water, and pull out all the gemstones!
STEP 4: Identify rocks at the assay station and take them home in a bag we provide — or purchase a custom Olentangy Caverns rock collector’s box.
