Price of Non-916 Gold: How to Calculate Value & Sell Non-Hallmark Gold
Many people own non-916 gold jewellery, old ornaments, or non-hallmark gold, but are unsure about its value. Questions like “How much is 1 gram of 916 gold?”, “What is the price of non-916 gold?”, and “How to calculate non-KDM gold rate?” are very common. This guide explains everything in simple terms, including how to calculate gold value based on purity and how to sell non-hallmark gold safely.
History of Hallmark and 916 Gold in India: Government Rules and Mandatory Hallmarking
In India, the concept of hallmarking and 916 gold was introduced to protect consumers from under-purity jewellery and unfair gold pricing. The Bureau of Indian Standards (BIS) launched the gold hallmarking scheme in the year 2000, initially as a voluntary system, allowing jewellers to certify gold purity such as 916 (22 carat), 750 (18 carat), and 999 (24 carat). Over the years, due to widespread misuse, inconsistent purity in jewellery, and customer complaints, the Government of India decided to strengthen regulation. As a result, mandatory hallmarking was officially implemented in phases starting from June 2021, making BIS hallmarking compulsory for specific caratages and regions. This move established 916 gold as the standard for jewellery in India, improved transparency in gold pricing, and made purity-based gold value calculation more reliable for buyers, sellers, and those dealing with non-hallmark or older gold.
How Much Is 1 Gram of 916 Gold?
The price of 1 gram of 916 gold depends on the daily 24 carat gold rate.

Calculation:
This is the pure gold value only, before any deductions.
What Is Non-916 Gold?
Non-916 gold means gold that has less than 91.6% purity.
This includes:
- Old jewellery
- Non-hallmark gold
- Non-KDM gold
- Jewellery with unknown purity
Common non-916 purities include:
- 900 gold
- 840 gold
- 750 gold (18 carat)
Price of Non-916 Gold (How It Is Calculated)
The price of non-916 gold is calculated using the same method as 916 gold — only the purity factor changes.
Formula
24 Carat Gold Price × Gold Purity Factor
Example: 840 Gold
How to Calculate Non-KDM Gold Rate?
Non-KDM gold simply means gold that is not certified or not marked, especially older jewellery.
To calculate the non-KDM gold rate:
- Start with today’s 24 carat gold price
- Find the tested purity (916, 900, 840, etc.)
- Multiply the price by the purity factor
This gives the actual gold value per gram, before deductions.
Gold Purity Conversion Table
| Gold Type | Purity % | Multiply By |
|---|---|---|
| 916 (22 ct) | 91.6% | 0.916 |
| 900 | 90.0% | 0.900 |
| 840 | 84.0% | 0.840 |
| 750 (18 ct) | 75.0% | 0.750 |
| 585 (14 ct) | 58.5% | 0.585 |
| 375 (9 ct) | 37.5% | 0.375 |
How to Sell Non-Hallmark Gold Safely
Non-hallmark gold can be sold legally in India, but sellers must be careful.
Important Points
- Gold should be purity tested
- Stones and impurities are deducted
- Pawn shops may undervalue non-hallmark gold
- Lack of hallmark does not mean low value, purity matters
Knowing the correct calculation helps you avoid losses.
Why Non-916 Gold Often Gets Undervalued
Non-916 and non-hallmark gold may get lower offers due to:
- Assumed low purity
- No hallmark certification
- High deduction margins
- Interest or charges (if pledged)
That is why calculating value before selling is important.
Key Takeaway*
- Daily gold price is always for 24 carat gold
- 916 gold value is 24 carat price × 0.916
- Non-916 gold value depends on actual purity
- Non-hallmark gold can still have high value
- Always calculate before selling
