Gold Purity Guide: 24K, 22K, 21K, and 18K Explained

Written by: AssetRateHub Market Research Team Reviewed by: Bullion Research Desk
Direct Answer / Quick Summary

Gold purity is measured in Karats (out of 24 parts) or Millesimal Fineness (parts per 1,000). 24K gold is 99.9% pure (Gold 999), 22K is 91.67% pure (Gold 916), 21K is 87.5% pure (Gold 875), and 18K is 75.0% pure (Gold 750). The higher the karat, the higher the pure gold content and monetary value.

What is Gold Karat and Fineness?

The word "Karat" (denoted as K or kt) indicates the proportion of pure gold out of 24 total parts. Pure gold without any added base metal is 24 Karats. Because pure gold is naturally soft and malleable, metals such as copper, silver, zinc, or nickel are alloyed with it to create durable jewelry.

How to Verify Gold Purity in Pakistan

In Pakistan, hallmark stamping (such as "916" for 22K) is standard at reputable jewelers. For independent verification, consumers can use certified XRF (X-ray Fluorescence) assay testing labs in major Sarafa markets (such as Karachi Saddar, Lahore Suha Bazaar, and Rawalpindi Raja Bazaar), which test purity without damaging the jewelry item.

Frequently Asked Questions

Is 24K gold suitable for daily wear rings and bangles?

No. 24K pure gold is too soft and can easily bend, scratch, or lose its shape under everyday pressure. 22K or 21K is recommended for jewelry, while 18K is preferred for stone-studded rings.

How is the price of 22K gold derived from 24K?

Multiply the 24K rate by (22 / 24). For example, if 24K gold is Rs. 451,799 per tola, 22K gold is approximately Rs. 414,149 per tola.
