The tiny numbers stamped on a piece of jewellery can feel like a secret code, but once you know what they mean, everything clicks into place. If you've spotted "750" engraved on a ring, chain, or bangle, here's the short answer: it tells you the piece is crafted from 18-karat gold, which all customers search 18 carat sone ka bhaav a blend that is 75% pure gold and 25% other metals.
At Goenka Jewellers, we believe a well-informed buyer is a confident buyer. Whether you're choosing a new piece or have inherited something special, understanding these marks helps you judge quality, authenticity, and real value before you commit.
What "750" Really Tells You
Seeing "750" means three-quarters of the metal is pure gold, while the remaining quarter is made up of metals such as copper or silver. Jewellers add these to harden the gold, because gold in its purest form is too soft to hold up to daily wear.
This is exactly why 18-karat gold is so beloved for fine jewellery. It keeps that deep, warm glow people associate with luxury, yet it's sturdy enough for rings and chains you'll wear for years. You'll usually find the stamp tucked away on the inner band of a ring or on the clasp of a necklace or bracelet, quietly confirming that what you're holding is the real thing.
How Gold Purity Is Measured
The Karat Scale
Gold purity is expressed in karats, with the scale running out of 24. So 24K is gold in its purest form, with nothing mixed in, but it's far too delicate for everyday jewellery. The most practical and popular grades sit lower on the scale.
Eighteen-karat gold (the "750" mark) gives you 75% pure gold. Step down and you'll find 14K at roughly 58.3% gold and 10K at about 41.7%. The lower the karat, the harder and more affordable the piece, but the less gold it actually contains. Keeping these figures in mind is invaluable whenever you buy or sell.
Why the Hallmark Matters
A hallmark is the small stamp that reveals exactly how much pure gold a piece holds. The "750" stamp points to 18-karat gold, while other numbers tell their own story: 999 signals nearly pure gold, and 585 indicates 14-karat. A quick glance for these marks can protect you from imitations and help you gauge a piece's worth with confidence.
Inside the Hallmarking Process
Hallmarking exists to guarantee that the gold you buy is genuinely what it claims to be. Independent assay offices test the metal, confirm its purity, and only then stamp it with the appropriate mark. That stamp becomes a small promise of quality. In many countries, this testing is even required by law to keep things transparent for shoppers. You may also see the gold written as "AU 750," meaning 750 parts of pure gold for every 1,000 parts.
It's worth noting that hallmarking traditions differ across the globe. In the United Kingdom, for example, a piece may carry several symbols, including a date letter and a maker's mark, alongside the purity figure. Other regions keep things simpler. The intention everywhere, though, is identical: to make sure you always know what you're buying.
Understanding Gold Alloys
The metals mixed into gold do more than add strength; they also shape its colour. In 18-karat gold, that 25% of alloy is often a combination of silver and copper. Adjust the recipe and you change the shade entirely.
This is how the familiar gold colours come to life. Yellow gold keeps tradition alive with a balanced, warm tone. White gold mixes in metals like palladium and is usually finished with rhodium plating for a bright, silvery shine that suits modern designs and engagement rings beautifully. Rose gold leans on extra copper to achieve its soft, romantic pink blush. Compared with 14-karat gold, which holds around 58.5% pure gold, the 750 blend offers a noticeably richer presence.
Exploring Different Types of Gold Jewellery
Beyond colour, gold jewellery also varies in how it's constructed. Solid 750 (18K) gold pieces carry that full 75% purity throughout, striking an ideal balance of beauty and durability for fine jewellery.
Gold-plated pieces, by contrast, wear only a thin layer of gold over a base metal; they're budget-friendly but tend to fade with time. Gold-filled jewellery sits in between, with a thicker, bonded gold layer that lasts considerably longer than plating. From a simple band to an elaborate engagement ring, there's a style and price point for every taste.
Buying Gold Jewellery Wisely
Two things deserve your attention when investing in gold: authenticity and value. Always begin by checking for that hallmark, since a genuine "750" stamp tells you the piece is true 18-karat gold. Reliable certification adds another layer of assurance. Real gold also carries a distinctive warm hue and a satisfying heft, so trust both your eyes and the weight in your hand, and buy only from dealers who are open about gold content.
When it comes to price, purity and the day's market rate drive the cost. Compare the current price of gold per gram against the weight of the piece to sense whether you're paying fairly, and remember that craftsmanship and intricate design rightly add to the total. If an offer looks too good to be true, treat it with caution, and never hesitate to ask for a clear breakdown of the price.
