Gold purity is one of the key factors used when valuing jewellery, coins and other gold items. Sona Buyers explains the testing and valuation process so customers can understand how purity, weight and the applicable market rate affect an offer.

Gold is assessed using appropriate testing methods together with physical inspection, weight and item characteristics. The purpose is to determine the purity or karat level before valuation.

Customers should be able to understand what is being tested and why it matters. Ask for the test result and valuation details before completing a transaction.

24K represents very high-purity gold, while 22K and 18K contain other metals to provide different physical properties. The actual value of an item depends on its verified purity, weight and the applicable rate.

Jewellery may also contain stones, solder or other non-gold components. These factors can affect the amount of gold considered for valuation.

After testing and weighing, the valuation can be explained to the customer before the sale is completed. Sona Buyers also provides today’s gold price information and instant cash for gold services.

For customers with pledged jewellery, see the pledged gold release service before selling.
