Testing the Gold
Customers bring their unwanted, damaged or broken gold jewellery to the Bullion kiosks to get it tested by one of the professional gold buying consultants. The process commences by the consultant answering any questions the customer may have and by sorting the gold offered by the customer into various groups for testing and valuing.
Each item is tested using jewellers’ traditional gold testing methods:
- The consultant views the item with a magnifying glass to determine whether it has carat markings
- The gold is then rubbed on a textured black touch stone, leaving a faint line of gold on the stone
- A variety of acid solutions is then dropped onto the gold line, which enables the consultant to determine the actual purity (carat value) of the item
To verify that the item is solid and not plated gold:
- By using a fine file, the consultant gently scratches the surface of the item (on a non-prominent area such as the inside of bangle or ring)
- A tiny droplet of acid solution is placed on the scratched surface – if it reacts in any way or changes colour, the item is not solid gold
The items are sorted into 9ct, 14ct, 18ct, 21ct, 22ct or 24ct groups. Each group is then weighed using a certified digital scale. The carat and weight for each group is then entered into the computer and a ‘buy price’ or offer is calculated and directly correlated to the prevailing gold price.
ALL THE STEPS ABOVE TAKE PLACE RIGHT IN FRONT OF THE CUSTOMER.
