Plastic Diamond Gauge

This diamond gauge is made out of clear acrylic that includes a precise measuring scale in carats, which helps in determining the size of diamond and gemstones. The gauge is useful for jewellers and gemmologists during the evaluation and sizing of gemstones in a setting. It can also be used to suggest what size stone a setting will accommodate.

The sizes are listed on the gauge:
Oval – 0.25ct, 0.50, 0.75ct, 1ct, 1.25ct and 1.5ct
Pear – 0.25ct, 0.50ct, 0.75ct, 1ct, 1.25ct and 1.5ct

To accurately determine the carat weight of a diamond, it is essential to weigh the diamond precisely and understand the relationship between its weight and size.
