Golden yellow sapphires are mined from alluvial deposits in Montana, primarily near Rock Creek and along the Missouri River. These are the only commercially viable sapphire deposits in the United States.
The golden yellow hue results from trace amounts of iron that replace aluminum atoms in the sapphire's crystal structure during formation. Higher iron concentrations produce deeper golden tones.
Montana sapphires rank 9 on the Mohs hardness scale, making them extremely scratch-resistant and suitable for daily wear in rings, bracelets, and other high-contact jewelry pieces.
