โ๏ธGem Mountain Sapphire Mine in Montana allows visitors to dig through gravel and search for sapphires.
๐งบSpecial techniques, such as washing gravel and using screens, help separate the sapphires from other rocks and dirt.
๐The sapphires found at the mine are typically small and have a rounded, tumbled look due to being deposited from an alluvial source.
๐ฅSome of the sapphires found can be heat-treated to enhance their color and clarity, resulting in more vibrant stones.
๐Reservations are required to visit the mine due to limited space and high demand.
