Montana's nickname, The Treasure State is a fitting one as sapphires can be found throughout the state.   Most can be attributed to four major locales:  Yogo Gulch, Rock Creek, Dry Cottonwood Creek, and the gravel bars along the Missouri River northeast of Helena. The Missouri River, Rock Creek, and Dry Cottonwood Creek deposits are associated with high yields of high-clarity fancy sapphires, with colors ranging from light pinks, purples, oranges, yellows, and greens, to pale blues.

Untreated Yogo sapphires are known for their excellent "cornflower blue" color and exceptional clarity; and many believe their natural qualities surpass heat-treated stones from all over the world.  However, their primary drawback is their small size.  Cut gems from Yogo Gulch are very rarely more than one carat in size.
