Why Your Gold Weighs Less: Cleaning & Accurate Weighing

Learn why gold may weigh less during valuation after ultrasonic cleaning. Discover how accurate weighing and purity testing ensure fair gold value.
Why Does Your Gold Weigh Less at Some Shops? Understanding Ultrasonic Cleaning and Accurate Gold Weighing
Customers who sell old gold sometimes notice that the weight shown during valuation is slightly different from the weight mentioned on the original purchase bill or remembered from previous measurements. This often creates confusion and raises questions about whether the weighing process is accurate.
The difference in weight is usually related to how the jewellery is cleaned and weighed before valuation. Factors such as accumulated dirt, dust, oil, and the precision of the weighing machine can all influence the final measurement.
