BIS Hallmark vs. KDM: Understanding Gold Purity at MP Jewellers HSR Layout
Buying gold jewellery is a significant investment, and understanding gold purity standards is essential before making a purchase. Many customers often come across terms like BIS Hallmark, KDM gold, and 916 gold, which can create confusion when choosing the right jewellery.
At a trusted jewellery store in Bangalore, educating customers about gold purity is a priority. Whether you are purchasing bridal jewellery, daily-wear ornaments, or investment pieces, understanding the difference between BIS hallmarked gold and KDM gold helps ensure you make a confident and secure purchase.
If you are visiting a reputed jewellery store in HSR Layout, knowing these purity standards will help you identify authentic jewellery and protect your investment.
What is BIS Hallmarked Gold?
BIS Hallmarked gold is jewellery that has been officially tested and certified for purity by the Bureau of Indian Standards (BIS), the national standards authority of India. This hallmark acts as a guarantee that the gold meets strict purity and quality standards.
The hallmark is applied after the jewellery is tested at BIS-approved Assaying and Hallmarking Centres, ensuring that the gold contains the purity level mentioned on the piece.
Components of a BIS Hallmark
A BIS hallmarked jewellery piece typically contains:
BIS logo
Purity mark (such as 22K916, 18K750, or 14K585)
Hallmark Unique Identification (HUID) number
Assaying centre mark
Jeweller’s identification mark
These marks confirm that the jewellery has undergone official testing and meets government-approved purity standards.
When customers visit a professional jewellery shop in Bangalore, they are encouraged to always check for BIS hallmark markings before purchasing gold jewellery.
What Does 916 Gold Mean?
The term 916 gold refers to 22-karat gold that contains 91.6% pure gold, with the remaining percentage made up of other metals to increase durability.
Pure 24-karat gold is extremely soft, which makes it unsuitable for jewellery. Therefore, 22-karat 916 gold is commonly used because it balances purity and strength, allowing intricate jewellery designs to be crafted without compromising quality.
A trusted jewellery shop in HSR Layout usually offers BIS-certified 916 hallmarked gold jewellery, which is widely accepted across the market for both wear and resale.
What is KDM Gold?
KDM gold refers to jewellery manufactured using a cadmium-based soldering process. In this method, cadmium is used as a filler metal to join gold pieces during jewellery making.
Typically, KDM jewellery may contain approximately 92% gold and 8% cadmium alloy, which was traditionally used to maintain gold purity during the soldering process.
However, the use of cadmium has raised health and environmental concerns, and this method has largely been discontinued in modern jewellery manufacturing.
Because KDM jewellery does not undergo BIS certification, it does not provide guaranteed purity verification, which makes it less reliable compared to hallmarked gold.
Customers visiting a reliable jewellery store in Bangalore today are usually advised to choose BIS hallmarked jewellery instead of KDM gold.
Key Differences Between BIS Hallmark and KDM Gold
Hallmarked jewellery provides transparency, authenticity, and trust, which is why it has become the preferred choice among modern jewellery buyers.
When shopping at a reputable jewellery store in HSR Layout, customers can confidently purchase BIS-certified gold knowing that the purity has been officially verified.
Understanding the difference between these two types of gold is crucial before purchasing jewellery.
Why BIS Hallmarked Gold is the Better Choice
Today, BIS hallmarked jewellery has become the standard for quality gold in India. Buyers prefer hallmarked gold because it offers multiple advantages:
1. Guaranteed Purity
Hallmarked jewellery undergoes strict testing, ensuring the gold purity matches the stated karat value.
2. Government Certification
The hallmark is issued by the Bureau of Indian Standards, providing official authenticity.
3. Better Resale Value
Jewellery with BIS certification usually has higher resale and exchange value because its purity is verified.
4. Consumer Protection
Hallmarking protects buyers from purchasing gold with lower purity than claimed.
At a trusted jewellery shop in Bangalore, customers are always guided to check the hallmark details before finalizing their purchase.
How to Identify Hallmarked Gold Jewellery
When purchasing gold jewellery from a reputable jewellery shop in HSR Layout, customers should look for the following hallmark indicators:
BIS logo – confirms certification by the Bureau of Indian Standards
Purity mark – such as 916 for 22K gold
HUID number – unique identification code for the jewellery piece

Jeweller identification mark
These markings ensure that the gold jewellery meets official standards and protects buyers from fraudulent claims.
