What Does 750 Mean on Gold Jewellery? 

A 750 stamp on gold jewellery means the piece is 18 karat gold, made up of 75% pure gold and 25% alloy metals like copper, silver or zinc. It is one of the most common purity marks you will find on fine jewellery sold across India today. 

You know the feeling. You're playing with your new ring in the light, maybe about to snap a pic for the gram, and you see a tiny "750" hidden inside the band. Your first thought is probably somewhere between “is this even real gold” and “wait should this have said 916”. Fair questions, and you are not the only one to ask them. That search is performed thousands of times a month, usually by somebody standing at a jeweller's counter or scrolling through an online cart, phone in one hand, ring in the other.

So we need to fix it right. 750 gold ? It's 18 karat gold. That's all. Not phoney, not watered down, not a step down from the 22K sets your grandmother wore. It’s a purity standard that is recognised across the globe and frankly, it’s the standard that most fine jewellery brands are built on (yes, including those dainty stackable rings all over your Pinterest boards right now).

If you have been seeing more 18K gold pieces on your feed lately, it’s not a coincidence. 750 gold is almost always the minimal, everyday gold jewellery that looks expensive but not loud. And we’re getting into it. There is a reason for that. 

750 Gold Purity Explained: The Math Behind the Mark 

Here is the part that no one explains simple enough. Gold is measured in purity on a scale of 24 parts, with 24 karat being pure gold. The purity of gold is given a number when it is mixed with other metals to make it wearable.

The purity of 750 gold is based on a system called millesimal fineness, which is simply “parts per thousand.” So 750 parts per 1000 is pure gold. Do the karat math and it comes out just right: 18 divided by 24 is .75, or 75%. So, you will find “18K” and “750” stamped interchangeably on the same piece of jewellery. Gold, also, two ways of writing it. 

In an 18k gold stamp 750 piece the other 25% is not filler. It is copper, silver, zinc or some mix of these, deliberately added to make the piece strong enough to actually survive being worn. 24K gold is so pure that it will bend if you merely glance at it cross-eyed. Nobody wants a wedding band that gets dented by a handshake. 

Is 750 Stamped Gold Real Gold in India? 

Short answer, yes. Real gold is real 750 carat gold, certified and legally recognised. The confusion is generally due to people assuming "lower karat" automatically means "less real" when in fact it just means "mixed with more strengthening metal".

How to tell real 750 gold from fake

A stamp is not proof alone. What makes it trustworthy is the system behind it. And specifically the BIS hallmark that should be right there next to the 750 number. If you see 750 and no BIS triangle anywhere near it, that’s your signal to ask more questions before you pay.

Can You Fake a 750 Stamp?

Yes, unfortunately, counterfeiters sometimes press false numbers into low purity metal. That’s exactly why hallmarking is a separate verifiable layer on top of the stamp. The 750 is the claim, the BIS hallmark is the receipt that backs it up. 

Understanding the BIS Hallmark on 750 Gold Jewellery 

In India, a 750 hallmark gold piece is not just stamped by the jeweller and left at that. Hallmarking is mandatory for gold jewellery sold in the country from June 2021 and it goes through the Bureau of Indian Standards, or BIS, an independent government body that tests and certifies purity.

The Four Elements of a True BIS Hallmark

Your jewellery should bear a full hallmark that includes:

BIS logo – a small triangular mark

Purity number - 750 in this case

Assaying and Hallmarking Centre mark – indicates which centre tested the piece HUID code – a unique 6 character alphanumeric code specific to that exact item 

What Is HUID and Why It Actually Matters 

HUID is Hallmark Unique Identification. Every hallmarked item has its own code, almost like a fingerprint, so it can be traced back to the exact jeweller and testing centre. This one detail is what actually protects you as a buyer, much more than the purity number alone.

Does 18K gold have to be hallmarked?

Yes, but there’s a small exception that most people don’t know about. At present, it is not mandatory for gold jewellery below 2 grams to be hallmarked. So if you have a small gold stud or a minimal charm below that weight and without a full hallmark, it doesn’t necessarily mean that there’s something amiss. But anything over 2 grams should get the full mark. 

How to Check 750 Hallmark on Gold Jewellery 

This is the part you should screenshot before you go on your next jewellery shopping spree.

Locate the stamp. Look on the inside of a ring shank, near a bracelet clasp, or on the back of an earring post.

See the BIS triangle. A magnifying glass or your phone camera zoomed in will work well.

Read the number of purity. Should be 750 for 18k gold.

Write down the HUID number. Six characters, mixed letters and numbers.

Verify online.  You can either open the BIS Care app or log in to the BIS portal and punch in the HUID to get the registered details of that particular item.

If the code does not match, or if there is no HUID at all on a piece over 2 grams, that is a real red flag and not to be brushed off.

750 vs 916 Gold: Which Is Better for You? 

This is probably the most searched comparison in Indian gold buying, and honestly, there is no single right answer. It depends on what you are buying it for. 

Purity and Value Comparison

Durability: Why 750 Gold Suits Everyday and Stone-Set Wear

The practical truth they won’t tell you at the counter. Golds of a higher purity like 916 are softer and usually do not hold gemstones as well over time. They tend to stretch out faster with daily wear. 18K gold, because of the added strength of the alloy, holds a stone in place for years. That's why most fine diamond jewellery around the world is made in 18K, not 22K.

Which One Should You Really Choose?

Imagine it as stages rather than one fixed rule. When you're buying your first real gold piece for yourself, something lighter and daily-wearable makes more sense early on. As your collection expands, the heavier traditional 22K pieces are reserved for weddings and special occasions, while 18K is what you reach for to wear every single day, the pieces that make up half of your outfit photos without you even trying.  

750 Gold Purity Percentage vs Other Karat Marks 

585 (14K) vs 750 Gold

14K gold is 58.5% pure, noticeably less gold content than 750. A lot less gold than 750 . It is more scratch resistant and usually cheaper, but if you are choosing between the two for fine jewellery meant to last then 750 offers a better balance of value and strength.

24K Gold 750 vs 999

24K is as pure as gold gets, but it is too soft for jewellery you plan to wear on a regular basis. That’s why you see 999 gold used for coins and bars, not for rings you’re wearing to work five days a week. 

Why 18K (750) Gold Is the Standard for Diamond Jewellery 

This is the part most gold guides skip entirely, and it is honestly the most useful thing to understand if you are shopping for anything with a stone in it. 

How Alloy Strength Holds Diamond and Gemstone Settings Securely 

A diamond doesn’t just sit on top of gold. It is held by small claws or a metal rim known as a prong or bezel setting, and that setting must hold fast for years without loosening. Softer gold like 22K just can't hold that grip as consistently over the long haul. 18K gold alloy has just enough strength to keep a stone where it needs to be, through gym sessions, dishwashing, everything. 

Prong and Bezel Settings: Why Softer Gold Falls Short 

Jewellers worldwide, from European ateliers to Indian fine jewellery houses, default to 18K for this exact reason. It is not a trend, it is a structural decision that happens to also look beautiful. 

Heer by GIVA's Approach to 18K Gold

Colours of 750 Gold: Yellow, White and Rose Explained 

Same 75% purity, three totally different looks, all depending on what metal is mixed into that remaining 25%.

Yellow gold is made with copper, silver and a touch of zinc for that classic warm tone

White gold is alloyed with metals like palladium or nickel and then often rhodium plated for its bright silvery appearance.

Rose gold is more coppery which is what gives it that soft pink undertone everyone has been obsessed with for the last few Pinterest seasons.

Choosing a Shade for Indian Skin Tones and Occasions 

Rose gold is a colour that complements warmer undertones beautifully and photographs incredibly well, which is probably why it dominates so many jewellery mood boards right now. Yellow gold is the safest bet and a versatile choice for everyday wear and compliments both Indian and western attires. If you want something a little more formal or minimal, white gold is a great option.

Where to Find the 750 Stamp on Your Jewellery 

The mark 750 on jewellery is usually hidden in places that do not interfere with the design.

Rings: inside band or shank

Bangles and Bracelets: (Near the Clasp/Opening)

Necklaces and Chains: At or Close to the Clasp

Pendants: on back or by bail side

Earrings: on post or back plate

If you can’t see a 750 stamp mark on gold somewhere on a piece that says 18K, then it’s worth asking the jeweller directly before you buy, especially for anything above 2 grams.

Daily Wear Tips for Humidity and Sweat 

Jewellery of any sort doesn’t do well in Indian summers, but 18K wears better on a daily basis than most. But take rings off when applying sunscreen, perfume or hand cream as chemical buildup will dull the shine faster than the gold itself will wear down.

Cleaning Without Damaging the Finish 

750 gold looks new with a soft cloth and mild soap water every couple of weeks. Avoid harsh chemical cleaners as these can affect the alloy finish over time, especially on white gold with rhodium plating.

Storing to Prevent Scratches 

Separate them, not rolled up together in one pouch. Gold is tough, but gold on gold will still scratch with years of storage.
