What Does 750 and 925 Mean on Jewellery? Hallmarks Explained

Imagine finding the perfect necklace and flipping it over to see a tiny stamp labelled 750 or even 925. What on earth does that even mean? 

If you’re assuming these are random numbers that mean nothing, you might want to think again. These numbers tell you exactly what you’re buying, and whether you’re really getting value for your investment. 

Think of these hallmarks as the jewellery industry’s secret code. We’ve taken it upon ourselves to walk you through what they mean. 

Let’s dive in, shall we?

What Are Hallmarks and Why Do They Matter?

Hallmarks are official stamps that indicate a jewellery item’s metal purity. It’s the guarantee that the piece’s metal composition truly meets the industry  standards. 

That’s exactly why hallmarks exist in the first place, because precious metals are valuable. Without these markings, which, by the way, are standardised across the globe, anyone could claim their jewellery piece was solid gold even if it wasn’t. Not a good situation to be stuck in, is it?

Hallmark stamps protect consumers and tell you: 

• What metal  the piece contains
• The percentage of pure metal versus alloy metals
• Often, where the piece was made or by whom

Take luxury houses such as Van Cleef Arpels or Cartier, for example. Every time you buy a piece from them, you’ll find a 750 stamped neatly inside. This is your guarantee that it’s made in 18-karat gold. This stamp represents centuries of standardisation and consumer protection. 

Be warned, though, fair reader: these hallmarks most definitely do not guarantee the authenticity of the entire piece. It’s a dangerous world out there, and hallmark stamps can be forged. 

What Does 750 Mean on Gold Jewellery?

Simply put, 750 means 18-karat gold that contains 75% pure gold. 

But what does that mean? 

Pure gold is 24 karats, meaning it’s r 100% gold and contains no other metals. However, pure gold is soft, prone to bending, scratching, and wearing out quickly, which is why jewellery pieces made from 24-karat gold wouldn’t withstand the everyday wear and tear that comes with life. 

This is why jewellers mix gold with other metals, such as copper, silver, nickel or palladium. This creates alloys that are still gold but a lot more durable. 

So, 750 gold is made up of 75% pure gold and 25% other metals. These metals, called alloys, provide gold with durability without sacrificing its value. 

You’ll frequently find the jewellery stamp 750 on: 

• Fine jewellery pieces, such as engagement rings, necklaces, and bracelets
• Luxury brand items, such as Cartier, Van Cleef Arpels, Hermès and Chopard
• High-end watches
• Designer jewellery across European and international brands

You’ll typically find the stamp inside the ring band, on the necklace clasp, or on the bracelet’s interior surface. It’s small, requiring careful inspection.

What Colours Does 750 Gold Come in?

Contrary to popular belief, jewellery stamped 750 doesn’t always look the same colour. That’s because the alloy metals create different finishes:

• Yellow 750 gold is the classic gold colour you’d imagine. It’s usually mixed with copper and silver
• White 750 gold has a silvery or platinum-like appearance, and is created by mixing gold with white metals such as palladium or nickel. It is  often rhodium-plated on the surface to enhance its bright white finish, and  for that extra bling! 
• Rose 750 gold comes in a beautiful pink tone. Since they’re primarily mixed with copper, that’s what gives it that warm blush colour. 

So, yes, all versions are 750 gold, they’re just finished differently through alloy choices and surface treatments! 

Is 750 Gold Real Gold?

We’ve seen lots of confusion about this, and it’s time we set the record straight once and for all! 750 gold is solid gold, that is neither plated nor filled. 

When you buy a piece of jewellery marked 750, you’re purchasing solid gold. The entire piece contains genuine precious metal. Wear it daily, inherit it, resell it, the gold remains valuable and intact! 

What Does 925 Mean on Jewellery?

A 925 hallmark stamp on a jewellery piece means it’s sterling silver and contains 92.5% pure silver. 

Sterling silver follows the same basic principle behind 750 gold. Since pure silver is too soft for jewellery, it’s alloyed with other metals for durability. 

925 silver is basically 92.5% pure silver, mixed with 7.5% other metals. That remaining 7.5% is typically either copper, which hardens the silver, or nickel and platinum. 

If you’re wondering why pure silver gets alloyed in the first place, that’s because pure silver, 99.9%, scratches pretty easily. A sterling silver bracelet worn daily would wear out pretty quickly, which is why the copper, or any other metals in the alloy, for that matter, create hardness without actually affecting the silver’s appearance! 

Common usage of 925 jewellery appears in: 

• Fashion jewellery brands
• Contemporary designer pieces
• Vintage and antique silver jewellery
• Fine jewellery houses (often for chains, delicate settings)
• Luxury brands using silver as an accent metal

What Does 925 Stamped on Jewellery Mean?

The 925 stamp on a piece of jewellery is basically a guarantee that the piece you’re investing in is genuine sterling silver. It’s been tested and confirmed to contain at least 92.5% pure silver. 

What Is CH 750 Jewellery?

Sometimes, you might run into stamps that read “CH 750 jewellery”. The 750, as mentioned earlier, means 75% pure, 18-karat gold. The CH part, however, is where things get a tad bit trickier. 

The CH typically refers to Confoederatio Helvetica, the Latin name for the Swiss Confederation. This usually means that the jewellery piece was either manufactured or officially hallmarked in Switzerland. 

The Difference Between 750 Gold and 925 Silver at a Glance

Here’s a quick side by side comparison of 750 gold and 925 silver: 

Characteristic	750 Gold	925 Silver
Pure Metal Content	75% gold, 25% alloys	92.5% silver, 7.5% alloys
Cost	Significantly higher	Considerably lower
Durability	Extremely durable, resists scratching	More prone to scratching, requires polishing
Look	Maintains lustre indefinitely	Tarnishes over time, needs maintenance
Weight	Heavy, substantial feel	Lighter weight
Value Retention	Excellent, precious metal value retained	Good, but silver prices fluctuate more
Daily Wear	Ideal for engagement rings, everyday pieces	Works for jewellery but needs regular care
Hypoallergenic	Gold rarely causes reactions	Silver can irritate sensitive skin
Resale Value	Strong resale market	Lower resale value than gold

If we’re perfectly candid, gold jewellery typically requires minimal maintenance. Silver jewellery, on the other hand, needs regular polishing to prevent tarnishing and is more prone to wear and tear from scratching.

For heirloom jewellery pieces you’d love to pass down to your children and grand children, we’d recommend investing in 750 gold since these have impeccable longevity. If on the other hand, you’re looking for pieces to wear daily, 925 silver is the best alternative. 

Can Jewellery Stamps Be Fake?

Absolutely. It’s a scary world out there, friends, and forged hallmarks are way more common than you’d like to believe. 

Here are some red flags for fake stamps:

• Poor engraving quality: Genuine hallmarks are crisp. Forged stamps appear smudged, irregular, or uneven.
• Inconsistent positioning: Authentic stamps are positioned in expected locations (inside the ring bands, on clasps). 
• Multiple conflicting stamps: Genuine pieces have standardised marking patterns. Confusing stamps suggest forgery.
• Stamps that look painted on: Real hallmarks are struck (impressed) into metal. If the mark appears to sit on top of the surface, it’s likely fake.

How Do You Verify Jewellery Authenticity?

If you’re investing in luxury jewellery, particularly pre-owned or resale pieces, proper verification is really important.

Start with a visual inspection. Examine the hallmark closely and check whether or not its crisp, properly positioned or consistent with the brand’s standard markings. Now is also a good time to check for other identifying marks, such as serial number, that match documented pieces.

Next, carry out a physical assessment. Weigh the piece. Since gold is dense, 18-karat gold should feel substantial. Feel the piece and check for a smooth and well-finished look, with no rough edges.
