Antique Yogo Sapphire & Diamond Pin

A client inherited this gorgeous antique Yogo Sapphire pin and asked us to appraise it.

Sapphires were known to occur in several areas of western Montana as early as 1865. For the most part, these deposits produced only moderately good sapphires. The discovery of sapphires in Yogo Creek was different. In 1895, famed gemologist G.F. Kunz, working for Tiffany’s of New York, labeled them “the finest precious gemstones ever found in the United States”.

The Yogo stones are prized for their good clarity and wonderful natural color, often called “cornflower blue”.
