Buying Lake Superior Agates
Sell us your lake superior agates and other local finds! For large collections or estates, we will travel. Due to the abundance of smaller agates, we do turn down many agate offers, but we still encourage you to bring us your finds. If you have larger agates—bigger than a golf ball—definitely bring them in or give us a call at (218) 834-2304.

Rock and Mineral Identification
Have something interesting you just found on the beach? Bring it in; we’ll help you identify it! However, if you have a large amount of stones you’d like us to look through, we do charge for our time and expertise. These situations will be handled on a case-by-case basis. Or, if you prefer, you can purchase one of the many guide books offered , including books written by the shop owners!
