Sapphire Montana is a type of sapphire that is found in the state of Montana in the United States. It is known for its rich, blue-green color, which is caused by the presence of iron and titanium in the stone.
Montana sapphires were first discovered in the late 19th century in the Rock Creek area of Montana. Since then, mining for sapphires has become an important industry in the state. Montana sapphires are typically found in alluvial deposits, which are deposits of sediment that have been transported by water.
