When selling gold jewelry, it is important to know the accurate weight. The most common measure for weight of gold is a gram scale. The gram scale will likely weigh in pennyweights, ounces or grams, but most prefer to weigh gold in grams.

Set the gram scale with calibration weights if necessary. If the scale automatically calibrates, use the method in the instructions.

Turn the gram scale on. Wait a few seconds for it to come on. It will likely display 88888 or something similar. Be sure it is set to grams.

To use the gram scale to weigh gold jewelry, gently lay the gold onto the gram scale on the flat side and check the reading.

Remove the gold jewelry from the gram scale. For optimal accuracy, turn the scale off and perform the process again. Turn the gram scale on, wait for the 88888, then 00. Lay the gold jewelry on the scale and read it again.

Remember that a gram is a tiny weight, and any slight variance is important in the weighing of gold jewelry. It takes approximately 31 grams to make a Troy ounce of gold. If the weight is not exactly the same, go through the process again. Some slight changes can be from the ceiling fan or air conditioner. A good gram scale is accurate to weigh gold jewelry if it is used correctly.

Take a photograph of the items on the gram scale if you intend to sell gold jewelry. This will give you proof of the weight and pictures of the items if there is ever a question.
