🔧 What it does & how to use

A gemstone sizing gauge for jewellers, gemmologists and hobbyists who need a quick, reliable way to check the size of loose round or baguette stones without scales. The plate carries a graduated series of cut-outs matched to stone sizes across the 1/100 to 2 carat range.

• Choose the shape: use the round cut-outs for round stones and the baguette cut-outs for baguette-cut stones.
• Start small: try the stone in the smallest opening first.
• Work up: move to progressively larger cut-outs until the stone sits flush without falling through or standing proud.
• Read the size: the marking beside the matching cut-out gives the stone's size/carat weight.
