Vintage sterling silver commemorative ring by Clark & Coombs, likely made in the 1950s or early 1960s for an employee of Sheller Manufacturing Co., a major mid-century automotive parts supplier. The face features a gold-tone panel (likely gold-filled or plated) with colorful enamel details and the word SHELLER across the center. Three red stones, assumed to be lab-created rubies, are set below the panel.

I assume this is a woman’s ring based on its size and proportions — size is approximately 6.75. These types of rings were commonly awarded for years of service or company milestones.
