Why should you ask for an invoice or a receipt?

It is recommended that you ask for an invoice for the gold you buy from a jeweller.2 The document puts in writing what you bought: what the item is, how many grams it weighs and what karat it is all stay on paper. Karat is the basic information that directly affects the value of gold; a wrong karat can cause the buyer a loss.4

What information should the document contain?

According to the sources, the invoice or receipt should state the item’s type, weight in grams and karat.1 If the item has a code, checking that this code also appears on the purchase document is one of the details to look at.3

InformationWhat it meansExample
TypeWhat the item isBangle, ring, gram gold
WeightThe item’s weight10 grams
KaratGold content (out of 24)22 karat
Item code (if any)The code or serial number on the itemSame as on the item

Example: a 10 gram, 22 karat bangle

Imagine you buy a 10 gram, 22 karat bangle. The document should state that the item is a bangle, that it weighs 10 grams and that it is 22 karat. On the bangle’s stamp you would also expect to see 22 karat (or its fineness equivalent, 916).

How do you compare the document with the item?

1Look at the stampThe item should have a karat stamp; the stamp is sometimes placed on the inside of the item.3
2Compare with the karat on the documentThe karat on the document should match the stamp on the item.3
3Check the codeIf the item has a code or serial number, it should not be worn and should match the information on the document.3
4Read the packagingFor gram gold, the packaging should show the weight, the purity (fineness) and the serial number.1

What if something does not match?

If the information on the document and the information on the item do not match, or a piece of information is missing, consider this carefully and ask the jeweller.3 A stamp on its own is not conclusive proof; fake items may have no stamp, or a fake stamp may be used.3 So when in doubt, karat is not guessed, it is measured: the common methods at the jeweller are the touchstone, the acid test and XRF analysis.
