What Gem Mountain Sapphire Mine is known for
Gem Mountain Sapphire Mine is Montana's oldest sapphire mine, letting visitors sift their own sapphire gravel at its seasonal mine site before having stones heat-treated, faceted, and set into jewelry back at its downtown Philipsburg store. The shop also sells finished sapphire jewelry, loose stones, and home décor items like teak furniture and amethyst cathedrals.
