THE MONTANA YOGO SAPPHIRE

They were tiny crystals born in the fiery depths of the earth, of aluminum oxide with traces of iron and titanium.  Yogo Sapphires are famous for their cornflower blue color, clarity and brilliance.  They are “all natural and untreated for color” unlike most colored stones including other sapphires.  The very rare Yogo Sapphire is a premier gemstone of the finest quality and a piece of Montana history.
