DIGITAL DIAMOND GAUGE (PRESID PEGG)

DIGITAL DIAMOND GAUGE (PRESID PEGG)

Ref: dg-presid-PEGG


Price: 349.00 Including VAT

Quantity:  

Measure the diamond horizontally and vertically, look up the measurements in the little book to see the weight, cleverly designed for different shapes not just rounds.

Also included, a chart listing 16 gemstones and a formula. You measure the stone in mm, find yourself a calculator and follow the formula to calculate the weight.

This is the only gauge that can be switched to carat (usually you can only measure in millimetres and must convert it); the only gauge I have seen that has an extra attachment for inserting into small items of jewellery.
Other features: clever power system, to turn it off you simply put the gauge back in its case - and that protects it - it is an exceptionally accurate and sensitive instrument.
