Tiffany jewelry is known around the world for its beauty, craftsmanship, and quality. When you look closely at a piece of Tiffany jewelry, you may notice small markings or stamps on the metal. One common mark is “750.” But what does this number mean? And why is it important?
In this article, we will explore the meaning behind the 750 stamp, its significance in Tiffany pieces, and how it relates to gold purity. We will also discuss how to identify real Tiffany jewelry and how to care for these precious pieces.
What Does the 750 Stamp Represent?
Understanding Gold Purity
The number 750 refers to the purity of gold used in the jewelry. Gold purity is measured in parts per thousand. Pure gold is 1000 parts out of 1000, or 100% pure. However, gold in its pure form is very soft. It bends easily and can scratch or break.
To make gold stronger and more suitable for everyday wear, it is mixed with other metals such as copper, silver, or palladium. This mixture is called an alloy.
The 750 mark means that the jewelry contains 750 parts of pure gold out of 1000. This equals 75% pure gold, or what is commonly known as 18 karat gold.
Why 18K Gold is Popular
18K gold offers a beautiful balance between purity and strength. It contains a high amount of gold but is still durable enough for fine jewelry. It has a rich, warm color that many people love.
Luxury brands like Tiffany & Co. often choose 18K gold for their fine jewelry collections. It offers elegance, luxury, and long-lasting wear.
Is 750 Gold Real?
Yes, 750 is Real Gold
The 750 stamp is a guarantee that the piece is made with genuine 18K gold. It is one of the most respected gold standards around the world, especially in Europe and the United States.
This mark is not only a sign of quality, but also a way to help buyers and collectors understand what they are purchasing.
How It Compares to Other Gold Types
Here’s how 750 gold compares to other common gold types:
- 24K gold (999) – 99.9% pure gold (very soft and usually not used for fine jewelry)
- 22K gold (916) – 91.6% pure gold (softer and less durable than 18K)
- 18K gold (750) – 75% pure gold (rich color and good durability)
- 14K gold (585) – 58.5% pure gold (harder, but less yellow in tone)
- 10K gold (417) – 41.7% pure gold (least expensive, more alloy)
So, 750 gold stands out as a luxurious and practical choice, making it perfect for high-end jewelry.
Why Tiffany Uses 750 Gold
A Standard of Excellence
Tiffany & Co. is famous for setting high standards in the jewelry world. Using 18K gold (750) is part of that standard. It reflects the brand’s commitment to quality and luxury.
When you see the 750 stamp on Tiffany jewelry, you are looking at a piece that was made with care, precision, and a fine balance of purity and durability.
Color Options and Style
Tiffany offers 18K gold in different colors:
- Yellow Gold – classic and timeless
- White Gold – modern and sleek, often rhodium-plated for shine
- Rose Gold – romantic and warm, with a pink hue from copper
All of these are 750 gold. The difference is in the mix of metals added to pure gold to create the desired color.
Where to Find the 750 Mark on Tiffany Jewelry
Check the Inside or Underside
The 750 stamp is usually placed in a discreet location. On rings, it is often on the inside of the band. On necklaces, bracelets, or earrings, it may be near the clasp or on a small tag.
Sometimes, it appears along with other marks, such as:
- “Tiffany & Co.” – confirming the brand
- “Made in Italy” or country of origin
- Other purity stamps – depending on the region (like “18K”)
Always Look for Consistency
A real Tiffany piece will always have clean, clear stamps. The engraving will be neat and precise, never messy or hard to read.
How to Know If Tiffany Jewelry Is Real
Check the Hallmarks
Genuine Tiffany jewelry will always have the proper hallmarks. These include:
- The Tiffany & Co. name in exact lettering
- The purity stamp, such as 750
- Sometimes a serial number, especially on high-end or limited pieces
Examine the Craftsmanship
Tiffany is known for its flawless craftsmanship. Real Tiffany jewelry will have:

How 750 Gold Wears Over Time
Durability and Wear
Since 18K gold contains a high amount of pure gold, it is softer than 14K or 10K. But it is still strong enough for everyday wear if cared for properly.
With regular use, 750 gold may develop a soft patina—a slightly darker look. Some people love this aged appearance, while others prefer the bright, polished look.
Avoid Harsh Chemicals
To protect your 750 gold Tiffany jewelry:
- Remove it before swimming in pools (chlorine can damage it)
- Avoid exposing it to cleaning agents or perfumes
- Store it in a soft pouch or lined box when not in use
Clean Gently
Clean 750 gold jewelry with:
- A soft cloth and warm water
- Mild soap, if needed
- A jewelry polishing cloth for extra shine
- Avoid abrasive materials that can scratch the gold.
Is 750 Gold Worth More?
Yes, It Has High Value
Because 750 gold is 75% pure, it is more valuable than 14K or 10K gold. The higher the gold content, the more expensive the piece.
When buying Tiffany jewelry marked 750, you are paying for:
- High gold content
- Timeless design
- Exceptional craftsmanship
- The brand’s prestige
Good for Investment and Heirlooms
Tiffany jewelry made of 750 gold can hold or even increase in value over time. Many people choose it for:
- Gifts on special occasions
- Heirlooms to pass down through generations
- Investment pieces that keep their worth
