We provide everything you’ll need to find your own Montana Sapphires. We have an excellent staff to do the heavy lifting and show you how to find your sapphires. Searching for your own Gem Mountain Sapphires is FUN! You find your very own sapphires. It rocks! (no pun intended) Good, kind-of-dirty, family fun! Wear your grubby clothes, or we have aprons for sale to help keep you clean.

Gem Mountain sapphires make stunning jewelry! When you’ve found all of your sapphires our expert staff can grade your sapphires for gem quality. Check the Heat Treating & Faceting section for more information. Nothing compares to wearing jewelry with a precious gemstone that you found!

We invite you to stop by and look for some precious Montana Sapphires of your own.
