Who We Are

Billings Gem & Mineral Club

We are a bunch of rock lovers (like you) committed to hunting, digging, and admiring our geologic finds all over Montana. Since 1959, we have helped many of our fellow rockhounds come out of the closet and learn to embrace their passion for rocks without shame!

Montana is a great place to rockhound because there is an abundance of geological features to view, eras to investigate, and types of rocks to be found. Agates, jasper, fossils, crystals, dinosaur bones, Indian artifacts, and more.

We are delighted to have you visit us!
