This sapphire originates from the alluvial deposits of El Dorado Bar in Montana, United States, a locality known for producing sapphire within the Missouri River system. Montana sapphires are typically recovered from secondary gravel deposits formed through weathering and river transport of corundum-bearing host rocks. This stone shows blue color and has received traditional heat treatment, a widely accepted practice used to improve color and clarity in corundum. Cut and polished in the United States.
