Gold and silver have long been considered more than just ornaments in Indian households. They represent tradition, financial security, and are often passed down through generations. But while gold’s value remains unmatched. This is why hallmarking your gold is now more important than ever-especially if you’re planning to sell gold for a fair price.
As one of India’s most reliable old gold buyers, HNS Gold Guwahati ensures complete transparency and value for your jewellery. Whether you’re looking for cash for gold or simply want to verify the purity of your item, understanding hallmark certification is key.
What is Hallmark Gold?
To protect consumers and maintain gold purity standards, the Government of India made hallmarking mandatory from June 2021. According to the Ministry of Consumer Affairs, Food, and Public Distribution, only around 30% of gold sold in India is hallmark-certified—despite its critical role in ensuring purity, especially for online and offline gold buyers.
A hallmark is an official stamp on gold or silver jewellery indicating its purity. This becomes crucial when someone decides to sell gold, as the hallmark assures the buyer of authenticity and protects both parties in the transaction.
Unfortunately, some jewellers may display their brand name as a purity mark, which holds no value during resale. At HNS Gold Guwahati, we always check for valid hallmark certification before offering cash for gold, ensuring you get the most accurate value.

These are the trusted indicators we look for at HNS Gold Guwahati when evaluating jewellery for customers who want to sell gold offers.
Why Choose Hallmark Gold Jewellery?
Gold is a high-value asset, and without proper certification, you could end up paying full price for a lower purity item—or get underpaid when trying to sell gold later. That’s why hallmarking matters.
By buying hallmark-certified jewellery:
- You’re assured of the gold’s purity.
- You avoid fraud.
- You gain better resale value-especially when working with reputed old gold buyers like HNS Gold.
We guide every customer through the hallmark verification process before giving a quote for cash for gold.
Components of a Hallmarked Gold Item
The Bureau of Indian Standards (BIS) governs hallmark certification in India. When evaluating your jewellery, look for these components:
- BIS Certification Mark (triangle logo)
- Purity Mark / Caratage (e.g., 22K916)
- Assaying Centre ID
- Jeweller’s Identification Mark
Additionally, always ask for a bill breakdown when purchasing new jewellery. As per the government, hallmarking charges are capped at ₹35 per gold item. This ensures transparency and makes resale easier when you wish to sell gold.
