Pearl Bead Thickness Measuring Caliper

A specialist caliper built solely for determining the physical dimensions of pearls and beads, with verified accuracy across the full 0–20 mm measurement span. Its linear scale is arranged for left-to-right reading, matching natural scanning patterns and reducing cognitive load during high-volume assessments. The tool’s low-profile jaws accommodate both flat-backed cabochons and fully rounded pearls without rocking or misalignment. Lightweight yet rigid construction prevents flex during measurement, preserving fidelity across repeated use. Frequently specified by UK craft suppliers and bead distributors for technical data sheets and product specifications.
