Coming In 2018...

We anticipate a limited selection of the following new items:

  • Mookaite slabs from Australia
  • Binghamite slabs from Minnesota
  • Great selection of petrified wood bookends
  • A nice selection of Montana sapphires, jewelry and faceted

Cooke City Rocks is interested in purchasing select specimens for future processing

We are also interested in:

  • Larger lapidary equipment
  • Lapidary estate sales
  • Fossils
  • Bear claws*

*The rules regarding buying and selling of bear claws vary by state. Some states prohibit buying, selling, both or neither. Montana state laws allows buying and selling of black bear claws, skins, and teeth from animals legally harvested. It is illegal to sell grizzly bear parts.

Can you ID these rocks?

Take a look at these photos and give me your best guess.
