Montana september sapphires come from alluvial deposits along the Missouri River and from the Yogo Gulch deposit. The color they produce is a steely blue to teal not found in other sources.
Style Notes
Unlike most pendant chains, which try not to be noticed, the rope chain's dimensional profile and surface complexity contribute their own presence to the composition.
Made With Purpose
The use of 10kt gold in chain manufacturing reflects the established relationship between alloy hardness and chain performance. Fine link styles including rope, Figaro, snake, and box chains require a metal that can be drawn into fine wire or stamped into small components while maintaining sufficient tensile strength to resist the flexion fatigue of daily wear. The harder alloy composition of 10kt gold addresses both the manufacturing requirement and the performance standard at the same time.
