Sometimes there will be a hallmark on your necklaces or rings. The most common hallmark we may see is S925 on silver jewelry. But what about your gold jewelry? You may see 10k/14k/18k hallmarks indicating different purity of gold. Other hallmarks are equivalent to karat, that is 375/417/585/750/999. This article will mainly dive into the 750 hallmarks of gold jewelry. Let's get started!
What is 750 Gold?
750 gold is a type of gold alloy consisting of 75% pure gold and 25% other metals, typically silver, copper, or palladium. The remaining 25% of other metals are added to improve the strength, durability, and color variations of the gold.
750 gold stamp is commonly found in European countries' jewelry and is also known as 18-karat gold in the United States. 18-karat gold is a popular choice for jewelry because of its balance of purity and durability. Often used for engagement and wedding rings, necklaces, and bracelets.
What Does 750 Mean on Jewelry?
When you see the 750 mark on your gold rings or necklaces, it means the jewelry is made of 18-karat gold. This means that 750 gold jewelry contains 75% pure gold and 25% other metals. 750 is the percentage of pure gold in the gold jewelry. 750 on gold means that out of 1000 parts of pure gold, there are 750 parts. What are the other 250 parts? The other 250 parts are the other alloying metals, including copper, silver, or palladium. Pure gold is relatively soft for everyday use, so mixing it with other hard metals makes it durable and hard enough for everyday use!
Gold Purity & Hallmark
On jewelry or other gold items, gold purity is usually indicated by a mark. In the United States, common markings include karat marks such as 10k, 14k, 18k, or 24k. The higher the karat number, the higher the gold content. In European countries, gold purity is often expressed in parts per thousand, such as 375, 585, 750, or 999, with higher numbers indicating higher gold content.
The hallmark "750" is a karat measure. A carat is a unit of purity for gold, with 24 carats being pure gold. Thus, 750 gold is also known as 18-karat gold.
Gold Purity | Karat Marking | Parts Per Thousand Marking |
10k | 10k | 417 |
14k | 14k | 585 |
18k | 18k | 750 |
24k | 24k | 999 |
Carat vs. Karat
"Carat" and "karat" are two terms often confused because of their similar spellings. However, carat is used to measure the weight of gemstones, while karat is used to measure the purity of gold.
Carat (ct): Carat is a unit of weight used to measure gemstones and pearls. One carat is equal to 200 milligrams. The carat determines the size and weight of gemstones in jewelry.
Karat (kt): Karat is a unit of purity used to measure the fineness of gold. It indicates the percentage of pure gold in a gold alloy. Pure gold is 24 karat, so 18 karat gold contains 18 parts pure gold and 6 parts other metals.
Is 750 Gold the Same as 18K Gold?
Yes, 750 gold is the same as 18k gold. Both terms indicate that the gold jewelry contains 75% pure gold and 25% silver and copper metals. The difference is in how the purity of the gold is expressed - in parts per thousand (750) or carats (18K). In both cases, the purity of the gold alloy is the same.
What Does AU 750 Gold Mean?
In addition to the 750 mark, you may see the AU 750 mark on your gold jewelry. AU 750 gold refers to a gold alloy with a purity of 750 parts per thousand, meaning it contains 75% pure gold on your gold jewelry. The "AU" stands for the chemical symbol for gold, which is derived from the Latin word "aurum". The number "750", the same as the 750 hallmark, indicates the purity of the gold in the alloy, with 750 parts per thousand being pure gold.
How to Tell if 750 Gold is Real?
When it comes to buying gold jewelry, the most important thing is whether the gold is real, especially when buying online. Fake 750 gold jewelry has a rough and dull surface. But there are some fake gold rings made to look more authentic. Don't worry! There are a few simple tricks to check if the gold is real or fake!
- Look for hallmarks: Genuine 750 gold jewelry often has hallmarks or stamps that indicate the purity of the gold. Look for markings such as "750," "18k," or "18kt" on the piece.
- Magnet test: Gold is not magnetic, so if a magnet attracts the piece, it is probably not real gold. This is an easy and quick test to rule out fake gold.
- Scratch Test: A scratch test involves rubbing the gold against a test stone to see the color of the streak. Real gold will leave a golden streak, while fake gold may leave a different colored streak.
- Acid test: Acid testing uses nitric acid to test the purity of the gold. A jeweler or professional can perform this test to confirm that the gold is indeed 750 gold.

Is White Gold or Rose Gold Eligible for the 750 Gold Hallmark?
Yes, the 750 Gold Stamp can be applied to white gold, yellow gold, or rose gold. The "750" stamp indicates the purity of the gold alloy, with 750 parts per thousand being pure gold. This means that a piece marked "750" contains 75% pure gold and 25% other metals, regardless of the color of the gold (white, yellow, or rose). The color of 750 gold is achieved by mixing pure gold with various metal alloys, such as silver, copper, or palladium, to create white, yellow, or rose gold variations.
- White gold (750): White gold is created by alloying pure gold with white metals such as nickel, palladium, or silver. The result is a silvery-white color similar to platinum. White gold is often plated with rhodium to enhance its whiteness and durability.
- Yellow gold (750): Yellow gold is the natural color of gold in its purest form. When alloyed with other metals such as copper and silver to create 750 (18-karat) gold, yellow gold retains its warm, yellow hue.
- Rose gold (750): Also known as pink or red gold, rose gold is made by mixing pure gold with copper. The higher copper content in the alloy gives rose gold a pinkish-red hue. The more copper in the mixture, the redder the gold appears.
