We love visitors of all ages. If you're planning a vacation in Montana join us for a sapphire mining experience the whole family will love. We're Montana's largest, oldest and funnest sapphire mine, with the best facilities, equipment and fun loving, helpful staff. Hidden in the mountains of Montana - we're hard to find but worth the drive.

Located between Hamilton and Philipsburg, Montana in the aptly named Sapphire Mountains you can discover your own Montana Treasure - a Montana sapphire gemstone from Gem Mountain. As seen on TV - Grab a bucket of sapphire gravel, belly up to the wash trough and find Montana sapphires. Depending how you handle your gravel and wash screen this might just be the dirtiest good, clean family fun you can have.
