How to Check Gold Purity: Complete Guide for Pakistani Buyers

Understanding Gold Purity

Gold purity is measured in karats, with 24K being the purest form of gold. In Pakistan, the most commonly used purities for jewelry are:

24K Gold (99.9% pure): Too soft for jewelry, primarily used for investment

22K Gold (91.6% pure): Most popular for jewelry in Pakistan

21K Gold (87.5% pure): Slightly harder, good for daily wear

18K Gold (75% pure): More durable, often used in modern designs

How to Verify Gold Purity

1. Check for Hallmarks

Always look for the hallmark on gold jewelry. The hallmark typically includes:

PSQCA certification mark (Pakistan Standards)

Purity grade (22K, 21K, 18K)

Assaying center's mark

Jeweller's identification mark

2. Acid Testing

Jewellers use nitric acid testing to verify gold purity:

22K gold remains unchanged when acid is applied

Lower purity gold will show reactions

This test should be done by professionals

3. Electronic Gold Testers

Modern jewellers use electronic testers that measure:

Electrical conductivity

Provide instant purity readings

Non-destructive testing method

4. Weight and Measurement

Use certified weighing scales

Compare weight before and after purchase
