When you come across a goldnecklace or ringmarked '750', you might wonder-what does it really mean? This number refers to the purity of the gold, a key factor in determining its quality and value.
In this article, we’ll uncover the mystery behind the 750 mark, explaining why 18K goldis a popular choice for fine jewelryand how to care for your precious pieces.
Understanding what "750" means can help you make more informed decisions when purchasing or maintaining your gold jewelry.
The History Of Gold Purity Marks
Before we delve into the specifics of 750 gold, it’s helpful to understand the history of gold purity marksand how they came to be. Gold has been used for coins, jewelry, and adornments since ancient times.
Early civilizations like the Egyptiansand Romanshad systems to measure the purity of gold, although these systems were not standardized.
As trade and commerce expanded in the 19th century, the need for a formalized gold purity marking systemgrew. Today, the most widely used method is based on the karat system(where 24Kis pure gold) and millesimal fineness(measuring gold in parts per thousand).
The 750 purity mark, indicating 18K gold, became the standard because it strikes the perfect balance between purity, durability, and affordability. This mark is now recognized worldwide, ensuring consumers can trust the quality of their gold jewelry.
What Does 750 Mean On Jewelry?
When you see the stamp '750' on a piece of jewelry, it signifies that the jewelry is made of 18K gold, containing 75% pure goldand 25% other metals. These other metals, such as copper or silver, are added to enhance the strength and durability of the gold. While 24K goldis 100% pure, it is too soft for most jewelry, which is why it’s alloyed with stronger metals.
The 750 markis simply another way of expressing 18K gold. To calculate the gold content, divide the karat numberby 24 (e.g., 18/24 = 750). This makes 750 goldthe perfect choice for those looking for jewelry that combines luxurywith practicality.

Identifying 750 Gold In Jewelry
To verify whether your jewelry is made from 750 gold, look for the hallmark stamped on the piece, which should be located inside a ring or on the clasp of a necklace. If you cannot find it or are unsure, a professional jewelercan verify the purity of your jewelry.
Look For Hallmarks And Stamps
The most reliable way to identify 750 goldis to look for the hallmark stamped onto the piece. In most cases, you’ll find the 750mark on the inside of rings, the back of bracelets, or on the clasp of necklaces. This mark signifies that the piece contains 75% pure gold, with the rest made up of alloys to enhance the strength and durability of the gold.
While 750is the most common marking for 18K gold, you may also find alternative marks like 18Kor 18Kt, which refer to the same purity level. It’s essential to ensure that the marking is clear and well-defined-poorly stamped marks can sometimes be an indication of counterfeit jewelry.
Check For Certification
