Gold is one of the most valuable and sought-after metals, but its purity and authenticity are crucial factors to consider before making a purchase. This guide explains gold purity, hallmarking, and how to ensure you buy genuine gold.
What is Gold Purity?
Gold purity is measured in karats (K) and represents the proportion of gold in an alloy. The higher the karat, the purer the gold.
Gold Purity Chart
| Karat (K) | Gold Percentage | Common Uses |
|---|---|---|
| 24K | 99.9% Pure Gold | Investment, Coins, Bullion |
| 22K | 91.6% Gold | Jewelry, Wedding Ornaments |
| 18K | 75% Gold | Jewelry, Watches |
| 14K | 58.3% Gold | Affordable Jewelry |
| 10K | 41.7% Gold | Budget Jewelry, Durable Accessories |
What is Hallmarking?
Hallmarking is a certification of gold purity, ensuring that the gold you buy meets the required standards. In India, hallmarking is regulated by the Bureau of Indian Standards (BIS).
BIS Hallmark Components
- BIS Logo – Confirms it is BIS-certified.
- Purity Mark – Indicates gold karat (e.g., 22K, 18K, 14K).
- Assaying & Hallmarking Center’s Mark – Identifies the testing lab.
- Jeweler’s Identification Mark – Identifies the jeweler.
- Year of Hallmarking (Letter Code) – Indicates the year of certification.
Why is Hallmarking Important?
- Ensures Purity – Prevents fraud and ensures you get what you pay for.
- Resale Value – Hallmarked gold has a higher resale value.
- Legal Compliance – As of June 2021, hallmarking is mandatory in India for gold jewelry.
How to Check Gold Purity at Home?
If you’re unsure about the authenticity of your gold, try these methods:
- Use a Magnet: Real gold is non-magnetic. If it sticks to a magnet, it’s likely fake.
- Ceramic Scratch Test: Rub the gold on an unglazed ceramic plate. If it leaves a gold streak, it’s genuine.
- Vinegar Test: Place a drop of vinegar on gold; if it changes color, it’s not pure.
- Check BIS Hallmark: Always look for the BIS logo and purity stamp.
Where to Buy Hallmarked Gold?
To ensure authenticity, buy gold from BIS-certified jewelers like:
- Tanishq
- Kalyan Jewellers
- Malabar Gold & Diamonds
- GRT Jewellers
- Bhima Jewellers
