Measure the stone, find a calculator, refer to the formula we give you, look up the gemstone (we give you constants for 16 gemstones), calculate the weight.


Brand: unbranded, made in China

Range: 0.01mm to 25.00mm

Tolerances: unknown. I can only guess: (this is not a guarantee) ± 0.02mm.

Accuracy: I'd guess (this is not a guarantee) it would be accurate to within 0.1mm when measuring 25mm (the error on smaller measurements would be less).

Units: millimetres or inches

Cuts: it will 'weigh' 12 different shapes

Takes one size LR44 battery (included) - lasts 1 or 2 hours of continuous use.

Measuring modes (mechanical): with the 'points' for loose stones and most mounted stones (note, these are 1.8mm in diameter so they will not fit through small mounts to reach the underneath of the stone); or with the 'wedge' for measuring the insides of holes (e.g. rub-over settings).
