This is one of our most exciting additions to the farm. Gem miners buy a bag of mining sand. We have several different bags available from $5 to $25. Each bag contains a variety of gems and in some bags fossils and a geode. Miners then put their bag of sand into a tray and into the water of the sluice and find their treasures as the sand washes away. Included in the activity is a collection bag for the gems and an identification card to help discover what each gem is. The Gem Mining activity has been a huge hit at the farm so far and we are sure you’ll love it too. Some of the bigger bags can be shared between several people.
