Product Details
  • Programmable Auto-Off Feature

    If you've ever had your scale turn off on ya in the middle of important measurements, you'll realize what a blessing this feature is. You can program this gem scale to turn off automatically, or to stay on until you turn it off yourself.

  • Protective Case

    This little jewelry scale comes with a hard, protective case to keep your scale, along with all of its accessories, nice and safe.

  • Bright Backlit Display

    This digital scale has a fancy backlit display to help ya see your weight readings, even in dim lighting.

  • Man, This Thing Is Tiny!

    You won't have to worry about this scale taking up space. It's just over five inches long, and only two and a half inches high.

  • Hinged Platform Protecting Cover

    This precision scale has a hinged hardcover ya flip down over the weighing platform when you're not using it. This helps prevent accidental damage to the load cells.

  • It Remembers The Last Unit Ya Used

    If your application needs weights in the same unit of measurement, (like ounces for instance), it can be a real pain if your scale always turns on ready to weigh in grams. It's a good thing the GemPro turns on displaying the unit of measurement you were using when ya turned it off.

  • Stainless Steel Platform

    The Gem Pro has a durable stainless steel weighing platform to make cleanup a breeze. Unlike gold or silver, stainless steel doesn't scratch easily and keeps its shine without rusting or tarnishing.

  • Easy Calibration

    To make sure ya keep getting the best weight readings from your scale, it helps to calibrate it from time to time. This jewelry scale has instructions to make calibrating your scale easy. The Gempro even comes with the 50 gram calibration weight ya need to use for regular calibration, however, if ya need to calibrate the linearity you'll need to pick up a 100 gram calibration weight because that one is not included.

  • Tare Feature

    The tare button on the front of this digital scale can be pressed to "zero out" the weight on the scale. You can then add more weight, and the display will only show the weight of the items you're adding. This sure is useful when ya want to use the included expansion tray to weigh your things, or if ya want to get separate weights of multiple items.

  • Liquid Level Indicator

    This very handy feature helps you quickly and easily get your scale nice and level. A level scale is important for getting the most accurate weight readings.

  • Five Useful Accessories

    The GemPro 500 comes with great accessories. Use Old Will's exclusive VibraKill® Pad under the GemPro to keep vibrations from messing up your weight readings, and the calibration weight to keep it nice and accurate. If you're looking to use the GemPro as a diamond scale or carat scale, the little expansion bowl is perfect for weighing those teeny tiny jewelry pieces, and the included tweezers make picking up those pieces easy. You even get an AC power adapter, just in case ya don't have any batteries on ya. You can store the GemPro500, along with the expansion bowl, tweezers, calibration weight, and adapter in the included protective storage case.

  • Kill Those Vibrations With VibraKill®

    Did ya know that vibrations can cause a scale's reading to bounce around from one weight to another? Included with this digital scale is a VibraKill® Pad to keep vibrations, (caused by everyday items like, your fridge, nearby music, your washing machine, etc...) from messing up your weighing.


    If ya have a problem with this scale, just send it to MyWeigh's warranty center in Phoenix, Arizona. They'll fix or replace your scale and send it on its way back to ya within a week of receiving it. You should expect your replacement to arrive in about two to three weeks from the day you send the original off. Keep in mind that sometimes MyWeigh runs out of stock, which can cause a delay in the warranty replacement process.

GemPro 500 Table top Jewelry Scale
Although I bought it for some other weighing, it has performed as advertised. It is very precise but does not take any longer than my old one. I am very satisfied with it AND the great help I received from the on line chat with Old Will Knott Scales. I highly recommend both!
