According to the Inspection Standard for Precious Metals Jewelry and the jewelry industry standard, the weight error standard of gold jewelry is: gold net weight 1g and below, and the allowable error is 0.1g; The net weight of gold is above 1g, and the allowable error is 0.3%. Therefore, it is reasonable that the error of 32g gold bracelet is between-0.3% and+0.7%.

But the actual weight of the bracelet you mentioned is 3 1- 15g, which is quite different from the 32g weight on the label. There may be the following situations:

1. The weight error is out of the standard range: if the actual weight of the bracelet is between 29 and 33 grams, then the error exceeds 0.3% specified by the industry standard, which is unreasonable.

2. Label error: The weight error may be caused by the label error. If the actual weight of the bracelet is between 3 1-32g, then the error is within the range specified by the industry standard, which is reasonable.

3. Wear leads to weight loss: If the bracelet has been worn for a while, it may cause weight loss due to wearing, resulting in weight error.

It is suggested that you can contact the seller or relevant institutions for consultation to ensure that your rights and interests are protected.
