Yogo Sapphire Jewelry

In 1895, gold miners in Montana were annoyed by "blue pebbles" clogging their sluice boxes. They didn't realize they were tossing away one of the rarest gemstones on the planet. Today, Yogo Sapphires are celebrated as the finest North American gemstone, prized for a clarity and color that rivals the best Kashmir sapphires.

What makes a Yogo special? Purity. almost all commercial sapphires are "cooked" (heat-treated) to improve their color. Yogo Sapphires emerge from the ground in Montana already boasting their signature electric "Cornflower Blue" and exceptional clarity. They are never heated, never treated, and 100% natural. Because of the difficult mining conditions in Yogo Gulch, large stones are incredibly rare, making every piece in our collection a scarcity. Whether set in a custom engagement ring or a solitaire pendant, owning a Yogo means owning a geologic miracle from our own backyard.
