Most precious metal items are marked with stamps and marks. Since ancient times, marking jewelry, coins, or even kitchen items has been a common practice. Therefore, valuable metal objects have been often used to commit fraud and forgery. - bulk sterling silver rings

This is why jewelers and coin makers implemented stamping to mark their products and protect them from fraudsters. Checking the weight and stamp on the ring will help you determine its value and what 925 means. Let's examine this topic more closely by looking at some facts and tricks.

Stamping and Marking

The stamp is usually placed on the inside of the ring. You may find it quite small so make sure to have a magnifying lens handy. The stamp may be one, two, or more letters, numbers, and sometimes a combination of both.

It is possible to get confused as different markings on a ring can mean different things. This can confuse the uninitiated. You should look carefully at all markings and learn about Marking 925.

The hallmark 925 stands for high-quality silver. Let's find out why this particular number is important. Pure silver is a silver item that contains 1,000 units. Pure silver, also known as fine silver, can be difficult to work with because it is extremely soft.
Only a small number of items and details can be made from pure silver, like ornaments or decorations on earrings or pendants. All other parts are made from silver mixed with a small amount of alloys.

Hallmarks 925

The most commonly used mark 925 when talking about silver jewelry or coins is Mark 925. These jewelry contain 92.5% silver and only 7,5% other alloys. It is strong and durable and can withstand mechanical and scratching. It is a popular metal for jewelers, who make rings, bracelets and necklaces out of it.

Different percentages of silver may have different markings. However, the most popular is 925. This is because stamping has changed over time. The reason for this is not only historical but also geographical. Let's see.

Through History, Stamping

You can find silver hallmarks 800, 958 and 999 in addition to 925. Sometimes, you might even find a stamp that says Italy or a hallmark with a lion sculpture. You can see that 999 is fine-silver, and 800 only 80% of this precious material.

Ancient Egypt

Old Egyptian silver is only 60% silver. This means you could be fooled into thinking that the band is very valuable . It is actually made of 600 of 1000 units of silver. This makes it almost worthless.


An earlier time, every European craft shop that traded with silver had a different stamp. Every piece of jewelry came with its own stamp that included details such as the date of manufacturing or the name of the shop.


Italy's sign, or the lion hallmark, indicates that this 925-quality piece of silver is from Europe. These marks are a guarantee that your sterling ring is a fine piece of jewelry.

Silver origins may show that the silver is not as pure and high quality as it should be. German silver can have an 800 hallmark, except for Egyptian. This signifies that the silver is not of high quality.


All silver items in the US had sterling or sterling silver hallmarks until the 1860s. This changed over time. Nearly all jewels and rings have the marking 925 between the 1960s and 1970s. These markings are a sign that your piece of jewelry is 92.5% sterling.

Valid stamping

You should ensure that you get the most valuable silver ring possible.
You can always check the value of any old jewelry if you find a different hallmark.

How to Test Silver Quality

It is always a good idea to have your silver ring checked in a certified jewelry shop or pawnshop. It's a quick and simple task that will allow you to quickly find what you have.

A professional will take a small amount of your ring and remove it from an unnoticed area. Next, apply a nitric acids to the silver. You can tell if the silver is sterling silver if it has a milky white hue. If it turns green, you'll know you have fake or silver coated ring.
If someone offers you an unmarked engagement ring, you should not buy it. It is usually made of cheap metal and plated with a thin silver layer. To avoid wasting money, you should always buy stamped rings.

A ring that looks and feels like silver, but has unusual hallmarks, is usually a sign that you have an antique piece. You can still find models that were made during the time when every jewelry shop had its stamps. You can only test the jewelry that you already own.


You should always check the hallmark on your ring to ensure that it is not worth less than the fair market value. The ring's price will vary depending on its quality and the model.
