These professional quality gem / jewellery scales offer touch screen convenience and superior accuracy to 0.005 carat precision. Stored in a strong box with foam protection and magnetic catch to protect the scales and slots to store the scoop, weighing tray and calibration weight.


Five different weighing modes are available - grams (g), carats (ct), grains (gn), Troy ounces (ozt) and pennyweight (dwt).  Also a parts counting feature with handy scoop included.


These are well built and accurate at an affordable price.  Perfect for those who are more serious about their gems and require a top quality set of scales.  Compared to many other scales (0.01ct.10g), these have double the capacity at 20grams with superior load cell quality and accuracy (to 0.005 carats).


NOTE: this batch of scales has the original packaging of zipper storage case with padding to securely hold the scales.  Separate areas to hold the calibration weight, tray and scoop so they are ready to hand when you need them.

  • Touch screen function
  • 20 gram capacity
  • 0.005 carat accuracy 
  • Low battery & Overload indicator
  • 20 gram calibration weight included

  • 6 months return warranty (excludes damage from dropping)

At this level of accuracy, stability of surface and air movement will cause fluctuations in the readout. This is normal for units with such highly sensitive readouts and should be taken into account during calibration and usage. 

To manually calibrate this unit, turn on and hold the MODE button down until "CAL" shows on the readout.  Press MODE again and when 20.000 shows on the readout, place the calibration weight gently on the weighing platform.  When "PASS" shows on the readout, scales are calibrated and can be used normally - you may need to just TARE off before weighing an item.

Great value scale and accurate

By: on 24 May 2024
Purchased this after previous model finally broke after many years of use. This new model, does tend to drift early. To combat this I turned it on and left it sit. Turns off after 3 mins so kept it on, after 5 min calibrated it and away we went. I tested against my A&D fx300, the little scale was constantly 0.02gr more. So 30.0 would read 30.02gr. Pretty close. I use this for reloading and apart from the initial drift, I'd recommend it. Great for those on a budget.
