Birthstone: September

Anniversary: 5th, 45th

Montana sapphires hold a special place in American gemstone history as the first gem-quality sapphires discovered in the United States. Found by gold rush prospectors in 1865 near the Missouri River, these beautiful stones were initially discarded in favor of precious metal until miners realized what treasures they'd been overlooking. Today, 150 years later, Montana sapphires are still being ethically mined from the western half of the state, primarily near the Missouri River, Dry Cottonwood Creek, Rock Creek, and the famous Yogo Gulch.

What makes Montana sapphires truly captivating is their incredible range of colors and exceptional clarity. Stones from the Missouri River, Rock Creek, and Dry Cottonwood Creek deposits showcase hues ranging from soft pinks and warm oranges to deep blues and delicate lavenders. The legendary Yogo Gulch produces some of the world's most coveted cornflower blue sapphires alongside rich blue-green varieties. Montana sapphires combine everything you want in a precious gem: stunning natural beauty, everyday durability with a hardness of 9 on the Mohs scale, and ethical sourcing close to home. Their unique American heritage and trusted provenance make them perfect for pieces that celebrate both patriotic pride and responsible luxury.
