Rectangular Diamond Gauge – One Arm – 0.01–4.00ct

This Rectangular Diamond Gauge is a one-armed metal sizing gauge designed for accurately measuring diamonds and other gemstones by carat size, ranging from 0.01 to 4.00ct.

The gauge consists of a metal sheet with precision-cut holes, each clearly marked with its corresponding carat size. To measure a stone, simply place the appropriate hole over the stone to obtain an indication of size and weight.

It can also be used to check stone sizes for settings—place the gauge over the setting and test each hole across the top until the nearest fit is reached. This makes it a practical tool for jewellers, setters and repair work.
