Diamond Estimation Loupe

The Diamond Estimator Scale Loupe is the perfect professional gemologist tool for quickly measuring the size/weight of diamonds both set and unset. This loupe can be used to estimate the weight of a mounted gemstone or to measure the table, facets, etc of the stone.

The distance between the measuring scale and the lens is adjustable so you can obtain a sharp image of the measuring scale imposed on the gemstone. The measuring scale ranges from 0 to 11 mm, in 0.1mm increments. Alongside the millimetre scale, there are corresponding approximate weights for round brilliant diamonds, eliminating the need to look up a separate chart for weight estimation.
