We work directly with miners in Montana to source our rough sapphires, then have each stone hand-cut by our dedicated team. Our cutting process is designed to remove as little material as possible, preserving the natural character, color, and shape of the original rough.

Rather than forcing each stone into a standardized shape, we create sapphires that are naturally one of a kind, with their own character and proportions.

This piece was created with recycled 18k yellow gold, our preferred gold alloy for its rich, warm color and beautiful density. 18k gold has a depth and warmth that we love, while still offering the strength and durability needed for everyday wear.

It’s a material chosen to be worn, lived in, and passed down for generations.
