How to Choose a Jewelry Scale

When purchasing gems, diamonds, or measuring carats, it’s imperative that you are equipped with a scale that can provide precise measurements. This is true for professional jewelers and artists as well as amateur collectors.

But how do you determine which scale is right for you? Well, there are a few important things to keep in mind.


Start with figuring out how much capacity does your jewelry scales need? In other words, will you be measuring very small items (< 20g)  or relatively large items on a regular basis? Next, figure out the level of accuracy required. For example, are you ok with accuracy within 1 gram, or do you need 0.001g precision?


Generally speaking, the greater the capacity and/or range of the scale, the less precise it will be. So a scale with a smaller capacity of 20g for example may have increments of 0.01g while a scale that accommodates 2000g will most likely only measure in increments of 0.1g at most, which could be all you need to measure a chunk of jade or other bulky stones.

In all likelihood, you’ll need a scale with a smaller range that can measure in very small increments for diamonds, gemstones, and other precious metals.  Good milligram scales usually boast precision to 1 milligram/ 0.001 grams.

This may mean that you will actually need to buy 2 or more different scales if you deal with jewelry in different sizes.

For example, if you weight large weights like pounds or kilograms you will need a scale specially for this. due to its larger capacity it will not be as precice.

Then you will probably need another scale for measuring small units like that of a single piece of jewelry that is accurate enough to give you good measurements small enough to ensure that the small pieces are accurate.

Measurement Units

Next, consider the measurement units. Good scales can count in troy ounces, grams, diamond weight total (dwt) and carats.

Tare/Calibration Function

This is a feature that allows you to place your stone(s) into a container and subtract the container’s weight, giving you the true weight of the stones. As a bonus, some scales even have memory features to help you keep track of your count of measurements.

Many jewelry scales have a tray built in for holding your gemstones, diamonds, and other precious metals, along with tweezers and calibration weights.

For high accuracy scales like jewelry scales calibration is also a very important feature that corrects any inaccuracies in the scale. High precision scales can be affected by many things and become inaccurate.

Some of the things that can make a digital scale incorrect include, temperature, level, movement, vibration, age, air movement, dust, and even light. this is why it is important to calibrate high precision scales regularly. Here is ou guide on how to calibrate your digital scales.
