Montana sapphires form in specific geological conditions found in the American Northwest. They often display a distinctive color range including golden yellow, and many retain their natural color without heat treatment. The state's deposits at Rock Creek and along the Missouri River produce gem-quality corundum recognized by gemologists worldwide.
Sapphire measures 9 on the Mohs hardness scale, making it suitable for rings worn daily. Only diamond surpasses sapphire in hardness among natural gems. This durability means your ring resists scratches from common contact with surfaces and objects.
Sterling silver contains 92.5% pure silver and 7.5% copper alloy. This standard, recognized internationally, provides the strength needed for jewelry settings while maintaining silver's natural luster. The .925 stamp indicates authentic sterling silver composition.
