Rock Knockers has a vast array of local rare minerals from
the Marquette Iron Range and the copper range of the Keewanee, Including
loads of associated minerals. We have the world's most beautiful dolomite
for sale; It's called "Kona Dolomite." We also
have plenty of Lake Superior agates, green stone, rare silver-copper half
breeds, rare datolite and a collection of some of the finest minerals found
elsewhere around the world. Our customers love our shop and our low prices.
If I'm not on the road or out collecting minerals, you'll find me at Rock
Knockers at da Trap. Come on in and we'll talk rocks!
