~I received this for my honest review, all opinions are 100% my own.~
I used to work for a jeweler and my husband now makes jewelry so I knew this would come in handy. It's a very nice scale. It's totally accurate and comes with calibration weights for recalibration of the scale. It also comes with a very nice quality pair of tweezers for moving stones and gems on and off the scale. It also includes a weighing tray so that item's do not roll off the scale. It also comes with batteries included which was a huge plus. My husband has found it very handy. He's used it quite a bit when listing and making his jewelry. It's a good quality piece for someone who needs a small scale at home. It's small and take's up no space at all.
