Gold jewelry is a timeless treasure, but it’s important to understand the purity and value of what you’re buying. Gold content can vary widely, even between pieces that look nearly identical.
Have you ever noticed a tiny stamp on your gold jewelry that reads “750”? That little number tells you a lot about the gold’s purity, composition, and ultimately, its worth.
This article will explore what the “750” stamp means, how it affects a piece’s value and durability, and how it stacks up against other gold purities.
What does “750” mean on gold jewelry?
When it comes to gold, purity is everything. You’ll usually see gold purity measured in karats, with 24 karats (24K) being as close to pure gold as you can get. But pure gold is very soft and easily damaged, so it’s not a great choice for jewelry. That’s why gold is often mixed, or alloyed, with other metals.
Alloying helps the gold hold up better, and it also changes the color of the gold.
If a piece of jewelry is stamped with the number “750,” that means the jewelry is made of 750 parts pure gold for every 1,000 parts of metal. In other words, it’s 75% pure gold.
A “750” stamp is the same as saying the jewelry is 18 karat gold (18K). The other 25% of the metal is usually made up of metals like silver, copper, or zinc, which alter the color and hardness of the gold.
The 750 mark is a sign of quality and value. The higher the gold content, the more valuable the piece is likely to be. The “750” stamp is there to assure you that the jewelry contains a certain amount of gold.
How does 750 gold compare to other purities?
Gold jewelry comes in different purities, so how does 750 (18K) gold stack up against the others?
750 Gold (18K) vs. 585 Gold (14K)
585 gold, also known as 14K gold, is made of 58.5% pure gold. Because it has a lower gold content, 14K gold is more affordable and durable than 18K gold.
18K gold, on the other hand, has a richer color and a higher value than 14K gold.
750 Gold (18K) vs. 999 Gold (24K)
999 gold, or 24K gold, is almost completely pure gold (99.9%). However, 24K gold is so soft that it scratches easily, making it impractical for most jewelry.
18K gold strikes a balance between purity and durability that you just can’t get with 24K gold.
Other gold purities
You may also see jewelry in these purities:
- 22K gold: 91.6% pure gold
- 10K gold: 41.7% pure gold. This is the minimum standard for gold jewelry sold in the U.S.
Gold alloys and their influence on color
When you see a piece of jewelry stamped with the number 750, you know that it’s 75% pure gold. The other 25% is made up of alloys that give the gold strength and can also influence its color.
The composition of 18K gold alloys
As mentioned, 18K gold is 75% gold. The other 25% is made up of other metals, and the specific metals included affect the gold’s color.
- Adding copper gives a reddish tone, resulting in rose gold.
- Adding silver or palladium results in white gold.
White gold and rhodium plating
Even though white gold contains alloys like silver or palladium, it’s still considered to have a “750 fineness,” meaning it’s 75% pure gold.
To enhance its brightness and durability, white gold is often plated with rhodium, a naturally occurring, silvery-white, extremely durable metal.
Identifying and caring for 750 gold jewelry
If you think you have a piece of 750 gold jewelry, take a close look for the “750” stamp or hallmark. Jewelers usually put the stamp in a spot that doesn’t show when you’re wearing the jewelry, like on the inside of a ring or on the clasp of a necklace.
Once you know you have a piece of 750 gold, you’ll want to take good care of it.
To clean the piece, gently rub it with a soft cloth and mild soap. When you’re not wearing your gold jewelry, store each piece separately in a soft fabric-lined box or pouch to keep it from getting scratched. You’ll also want to avoid exposing your gold jewelry to harsh chemicals like chlorine and bleach.
