| Overview: Understanding the difference between hallmarked gold and KDM gold, and the difference between KDM and 916 gold is crucial for making informed purchasing decisions. This guide explains purity standards, regulatory compliance, health implications, and financial considerations to help you choose the right gold type for your investments and personal use. |
What Is Hallmarked Gold?
Hallmarked gold represents the gold standard in India’s jewellery market. It carries official BIS certification, guaranteeing its purity level. The difference between hallmark gold and KDM gold becomes evident when you examine the certification process.
Each hallmarked piece displays five key marks:
- BIS Standard Mark: Official Bureau of Indian Standards logo
- Purity Grade: Such as “22K916” indicating 22 carats with 91.6% purity
- Assaying Centre Mark: Identifies the testing facility
- Jeweller’s Mark: Unique identification number
- Year Code: When hallmarking occurred
Benefits of Hallmarked Gold
Investment Security: Hallmarked gold maintains better resale value because its purity is pre-verified. When you need quick liquidity, lenders prefer hallmarked gold for loans since valuation becomes straightforward.
Loan Advantages: Banks and NBFCs readily accept hallmarked gold as collateral. The difference between KDM and hallmark becomes crucial here—lenders can offer up to 75% of hallmarked gold’s value as per RBI guidelines.
| Pro Tip: Always verify the six-character HUID number on BIS website before purchase to ensure authenticity. |
What Is KDM Gold?
KDM gold contains 92% gold and 8% cadmium, used as a soldering agent. However, understanding the difference between KDM and 916 gold reveals a critical health concern that led to KDM’s ban.
The Bureau of Indian Standards banned KDM gold in January 2017 due to cadmium’s toxicity. Medical research linked cadmium exposure to:
- Respiratory problems
- Kidney damage
- Cancer risks
- Hormone imbalances
- Contact dermatitis
The difference between hallmark gold and KDM gold includes this safety aspect—hallmarked gold uses safer alloys without toxic substances.
What Is 916 Gold?
916 gold indicates 91.6% purity, equivalent to 22-karat gold. The number “916” represents parts per thousand of pure gold. This standard helps understand the difference between KDM and 916 gold in terms of composition and market acceptance.
916 Gold Characteristics
| Aspect | 916 Gold Details |
| Purity | 91.6% pure gold |
| Karat | 22K |
| Alloy Content | 8.4% other metals |
| Market Standard | Most popular in India |
The difference between hallmarked gold and KDM gold becomes clear when considering 916 gold—it can be hallmarked if it meets BIS standards, while KDM cannot receive hallmarking due to cadmium content.
Key Differences: Hallmarked vs KDM vs 916 Gold
The table below summarises the key differences between the three:
| Factor | Hallmarked Gold | KDM Gold | 916 Gold |
| Certification | BIS certified | Banned since 2017 | Can be hallmarked |
| Health Safety | Safe alloys | Toxic cadmium | Safe when hallmarked |
| Loan Eligibility | Highly preferred | Not accepted | Accepted if hallmarked |
| Resale Value | Higher | Problematic | Good if certified |
| Legal Status | Compliant | Illegal to sell | Legal |
Practical Example
Consider Priya buying gold worth ₹2 lakh. If she chooses hallmarked 916 gold, she gets:
- Guaranteed purity verification
- Better loan eligibility (up to ₹1.5 lakh against 75% LTV)
- Higher resale value
- Health safety assurance
The difference between KDM and hallmark becomes financially significant—KDM gold offers none of these benefits.
Types of Gold and Their Usage
Investment Gold: Hallmarked 916 gold works best for long-term investment. The difference between hallmark gold and KDM gold shows clearly in investment returns and liquidity options.
Jewellery Gold: 18K hallmarked gold (75% purity) suits daily wear jewellery, offering durability while maintaining good value.
Loan Collateral: Only hallmarked gold qualifies for quick loan processing. The difference between KDM and 916 gold matters significantly when you need emergency funds.
Making the Right Choice
Understanding the difference between hallmarked gold and KDM gold, plus the difference between KDM and 916 gold, empowers you to make informed decisions. Always choose hallmarked gold for safety, investment value, and financial flexibility.
When selecting gold, prioritise BIS-certified pieces with proper documentation. This ensures you’re getting genuine purity levels while maintaining eligibility for future financial products. Whether you’re building wealth through gold investment or need collateral for emergency funding, hallmarked gold provides the security and recognition you need in India’s regulated market.
