What is the Stamp on a Diamond Ring?
When you purchase a diamond ring, you may notice a small stamp or inscription on the inside of the band. This stamp is often referred to as a “hallmark” and serves as an indication of the ring’s metal content and quality. The hallmark can also provide information about the ring’s manufacturer and the country of origin.
In this article, we will explore the different types of hallmarks, their significance, and how to decipher their meaning. We will also provide tips on how to ensure that the hallmark on your diamond ring is genuine and accurate.
Understanding Hallmarks
Hallmarks are typically small, discreet stamps that are applied to the inside of a ring’s band. They are usually less than 1 millimeter in size and may be difficult to spot with the naked eye. However, a magnifying glass or jeweler’s loupe can be helpful in identifying and deciphering the hallmark.
There are several different types of hallmarks that can be found on diamond rings. The most common type is a “karat mark,” which indicates the purity of the metal used to make the ring. Karat marks are typically expressed in 24 parts, with 24 karat being pure gold and 18 karat being 75% gold. Other common hallmarks include:
- Milgrain: A decorative border of tiny beads or granules.
- Filigree: Delicate, intricate metalwork with woven or twisted threads.
- Engraving: Personalization or decorative designs etched into the metal.
- Chasing: A technique that involves hammering or punching designs into the metal.
- Repoussé: A technique that involves hammering or punching designs from the reverse side of the metal.
Significance of Hallmarks
Hallmarks are important because they provide valuable information about a diamond ring. The karat mark indicates the purity of the metal used to make the ring, which can affect its durability, color, and value. Other hallmarks can provide information about the ring’s manufacturer, the country of origin, and the date it was made.
For example, a ring with a “18K” hallmark indicates that it is made of 18-karat gold, which is 75% pure gold. A ring with a “925” hallmark indicates that it is made of sterling silver, which is 92.5% pure silver. A ring with a “PT950” hallmark indicates that it is made of platinum, which is 95% pure platinum.
Tips for Ensuring Authenticity
It is important to ensure that the hallmark on your diamond ring is genuine and accurate. There are several things you can do to verify the authenticity of a hallmark:
- Examine the hallmark carefully. The hallmark should be clear and legible. If the hallmark is faint or difficult to read, it may be a fake.
- Compare the hallmark to other rings. If you have other diamond rings, compare the hallmarks on the rings to see if they are similar. If the hallmarks are different, one of the rings may be fake.
- Take the ring to a jeweler. A jeweler can examine the hallmark and tell you if it is genuine. The jeweler can also tell you the purity of the metal used to make the ring and the country of origin.
FAQ
Q: What is the difference between a hallmark and a carat?
A hallmark indicates the purity of the metal used to make a ring, while a carat indicates the weight of the diamond in the ring.
Q: What is the highest karat gold that can be used in jewelry?
24-karat gold is the highest karat gold that can be used in jewelry. However, 24-karat gold is very soft and is not suitable for everyday wear. Most jewelry is made of 18-karat or 14-karat gold, which is more durable and less likely to tarnish.

The “925” hallmark indicates that a ring is made of sterling silver, which is 92.5% pure silver.
Q: What is the difference between platinum and white gold?
Platinum is a naturally white metal, while white gold is an alloy of gold and other metals, such as palladium or nickel. White gold is plated with rhodium to give it a white color.
