What is 916 gold? It means 91.6% pure gold, which is 22 karat

If you have looked at a gold bill, a bangle, or a hallmark stamp and seen the number 916, you have probably wondered what it actually means. It is one of the most searched gold questions in India, and the answer is simpler than the jargon makes it sound. This guide explains 916 in plain language, shows how it lines up with karat and purity, and tells you how to check that your 916 gold is genuine and what it is worth.

What 916 means

916 is a purity number. It tells you how much of the metal is actually pure gold. Read it as a fraction out of 1000: 916 parts pure gold per 1000 parts of metal. Do the maths and 916 divided by 1000 is 0.916, or 91.6 percent. So when a jeweller, a bill or a stamp says 916, it is saying the gold is 91.6% pure.

This way of writing purity is called fineness. Instead of karat, it states purity directly as parts per thousand. It is the same system used worldwide: 999 fineness is 99.9% pure, 750 fineness is 75% pure, and 916 fineness is 91.6% pure. India uses fineness numbers like 916 on hallmarks because they are exact and leave no room for guessing.

Is 22K the same as 916? Yes

Yes, 22K and 916 are exactly the same gold, written two different ways. Karat measures purity out of 24 parts, where 24K is pure gold. So 22 karat means 22 parts gold out of 24. Work that out: 22 divided by 24 is 0.9166, which rounds to 91.6 percent, and 91.6 percent written as fineness is 916.

That is the whole link. 22 karat, 91.6% pure, and 916 fineness are three names for one thing. When you see "22K916" stamped together on a hallmark, it is not two grades. It is the karat (22K) and the fineness (916) of the same single purity, printed side by side so there is no confusion.

What 91.6% purity means in practice

91.6% pure means that out of the total weight of the metal, 91.6% is gold and the remaining 8.4% is other metals. Those other metals, usually copper, silver or a little zinc, are called the alloy. They are added on purpose, and we will get to why in a moment.

Here is what it looks like in real weight. Take a 10 gram 916 chain. About 9.16 grams of that is pure gold, and roughly 0.84 grams is alloy. Take a 20 gram 916 bangle and about 18.32 grams is pure gold. This matters when you sell, because a fair gold buyer pays you for the actual gold content at the day's rate, not for the alloy.

Why 916 and not 999

If 999 (24K) gold is purer, why is most jewellery made from 916? The answer is durability. Pure 24K gold is very soft. A ring or chain made from it would bend, scratch and lose shape with daily wear. It simply cannot hold fine detail or a clasp for long.

Adding that small 8.4% of other metals makes the gold much harder and tougher while keeping it visibly rich and yellow. 916 is the sweet spot India settled on: high enough purity to hold value and look like real gold, hard enough to survive being worn every day, set with stones, and passed down for years. That balance of workability and durability is exactly why 916 became the default for ornaments, while 999 is kept for coins and bars where softness does not matter.

The 916 hallmark: what is actually stamped

In India, gold jewellery is hallmarked by the Bureau of Indian Standards (BIS). A genuine BIS hallmark on 22K gold has three parts, and it is worth knowing all three so you can spot a real mark:

• The BIS logo. A small triangular mark. This is the certifying body's stamp and the first thing to look for.
• The purity grade. Shown as 22K916 (or just 916). This confirms the gold is 22 karat, 91.6% pure.
• The HUID code. A 6-character alphanumeric code, for example a mix of letters and numbers. HUID stands for Hallmark Unique Identification. It has been mandatory since 2021, and every hallmarked piece carries its own unique HUID.

The older hallmarks used to also show a jeweller's mark and an assaying centre mark. Under the current system the 6-character HUID replaces those, because the code itself ties back to the registered jeweller and the testing record. If a piece is sold as hallmarked but has no HUID, treat that as a reason to ask questions. For a deeper walk-through, see our guides on gold hallmarking and the HUID code.

916 vs other gold purities

916 sits in the middle of the purity range. Here is how the common hallmark fineness numbers, their karat, their purity and their typical use line up. Tables like this are the quickest way to see where 916 fits.

The big two to remember are 916 for everyday Indian gold jewellery and 750 (18K) for diamond and stone pieces, where the harder alloy holds the stones better. If you want to dig into the top of the table, our guide on 22K vs 24K gold compares 916 and 999 in detail.

Is 916 gold good, and where is it used?

916 gold is good, and for jewellery it is arguably the best practical choice in India. It is the standard for wedding sets, festival purchases, bangles, chains, necklaces and the gold that families buy to keep and pass on. When someone says they bought "22 carat gold" for a wedding, they almost always mean 916.

Because it holds high value and is universally recognised, 916 is also easy to sell back. A trustworthy gold buyer will weigh it, confirm the 916 purity from the hallmark, and pay for the gold content at the current rate. That is one more reason 916 is so dominant: it is liquid, recognisable and trusted across the whole market. You can check today's gold rates any time to see what 916 is fetching.

How to verify your 916 gold is genuine

Verifying 916 gold is straightforward, and you can do most of it yourself for free:

• Find the hallmark. Look for the triangular BIS logo, the 22K916 grade, and the 6-character HUID. All three should be present on genuine hallmarked gold.
• Check the HUID in the BIS Care app. Download the official BIS Care app, open the verify HUID option, and enter the 6-character code. It shows the registered jeweller and the certified purity. This is the single best free check.
• Get it assayed if in doubt. For older or unmarked gold, a BIS-recognised assaying and hallmarking centre can test the actual purity. This is the most accurate option.

If you want the full step-by-step, see our guides on the BIS hallmark check and how to test gold purity at home and professionally.

What your 916 gold is worth

The value of any 916 piece comes down to two things: how many grams of pure gold it holds, and the day's gold rate. Since 916 is 91.6% pure, you take the weight, multiply by 0.916 to get the pure gold content, and value that at the current rate. A fair buyer does exactly this and does not charge you for the alloy weight.

You do not have to do the sums by hand. Use our 916 gold value calculator to get an indicative figure for your piece, and cross-check it against today's rates before you sell.
