Description

The Presidium Dial Gauge (PDG) is a precision millimeter gauge designed for gemstone measurement, weight estimation, and ring sizing. Functioning similarly to the Leveridge gauge, the PDG delivers enhanced performance through a patented nonstick rack and pinion slide mechanism that provides noticeably smoother action during use.

Built with components manufactured in Switzerland and assembled in Singapore, the PDG is approximately 20% lighter than the original Leveridge gauge—reducing hand fatigue during extended bench sessions without sacrificing accuracy. Measurements are read directly from the dial in 0.1 mm increments across a full range of 0.0–23.0 mm, making it suitable for a wide variety of gemstones, settings, and ring shanks.
