Frequently asked questions

What does 916 mean on gold?

916 is the hallmark for 22K gold: 91.6% pure, a factor of 0.9167 against 24K. On 9 August 2026 that makes a tola of 22K Rs 421,100 against Rs 459,400 for 24K.

How do I convert karat to purity?

Divide the karat by 24. 22 ÷ 24 = 0.9167, 21 ÷ 24 = 0.875, 18 ÷ 24 = 0.750. Multiply the 24K rate by that factor for the metal value.

How much will a jeweller pay for my old gold?

The pure metal content at the board rate, less a deduction of roughly 5–15% for refining loss and margin. Making charges from the original purchase are not recovered.

Is Gulf 21K gold worse than Pakistani 22K?

It is lower purity, not lower quality. 21K is 87.5% gold and 22K is 91.6%, so value the piece by its actual karat rather than assuming a market standard.

How can I check purity without a lab?

Look for the hallmark stamp first, then ask for an electronic purity test — most established sarafa shops have an XRF or touchstone test and will run it while you wait.
