If you’ve seen something marked as sterling silver, you may assume that it’s no different from regular silver. However, that’s not the case. These two terms may sometimes be used interchangeably, but they’re not truly equivalent.

Sterling Silver Vs Silver

There is a difference between sterling silver and standard silver, and if you’re buying a lot of different silver jewelry, you should know exactly what it is you’re purchasing.

Antique Silver Vs Sterling Silver

What is Pure or Fine Silver & How Pure is Sterling Silver

If you’re purchasing something that is advertised as pure silver, that means it has 99.9% silver in it. It’s as pure as you can get there’s no such thing as 100% silver with no impurities. Fine silver is not used in jewelry because it’s simply too soft. The items would be too malleable by hand. That’s why the silver jewelry and other items you purchase will be made from a mixture of silver and another metal (or several metals).

Know What is Sterling Silver?

Sterling silver, on the other hand, is a silver alloy. It’s made when pure silver is mixed with copper. The result is an alloy that is not as soft as pure copper and is much more durable. Sterling silver is generally 92.5% pure. That means only 7.5% of the mixture is another metal. While copper is the most common, zinc and nickel are also often used in making sterling silver.

In many cases, items that are made out of sterling silver are actually coated with pure silver. This thin layer improves the look of the piece by making it shinier. However, these products should never be labeled as pure silver because they aren’t.
You should also look for the term “sterling silver plated” on products. These products are not made of sterling silver. Instead, they’re made out of other metals such as copper or nickel. They’ve just had an outer layer of sterling silver applied to them. Over time, this layer is going to start wearing off, leaving the item looking much less attractive.

What is Coin Silver?

If you’re researching sterling silver vs. pure silver, you may also see the term “coin silver” come up. This is another type of silver alloy. However, it’s less pure. Coin silver is generally no more than 90 percent pure silver, so it’s not used in jewelry that often.

How Do You Tell the Difference?

Reputable silver makers should always stamp their creations. On fine silver pieces, you’ll find a number that shows the amount of silver per hundred parts (or thousands, in some cases). The higher the number, the more silver is in the product. Pure silver should have a high number such as 999 (some items are marked as 99.9 or as .999, but these are all indicative of pure silver). On sterling silver, you should see 925 (or, again, 9.25 or .925). If the number is any lower than that, it shouldn’t be marked as sterling silver in the U.S.

Note that sterling silver sold in other countries may have a purity lower than 925. Not all countries have the same purity requirements that the U.S. has.

How to tell if something is silver plated or solid silver?

You have a prized silver antique collection, but do you know if it is solid silver of simply silver plated? Does it really make a difference? It does if you are concerned with the value.

Silver plating was developed as an inexpensive way for people who couldn’t afford sterling (or solid silver) to enjoy the beauty of the metal without the hefty price tag. In fact, some manufacturers got so good at creating silver plated items that it is sometimes difficult to tell the difference between the two. Unfortunately, when it comes to the value of your antiques, whether you have solid or plated silver makes a big difference, so it is important to be able to differentiate between the two.

Look for a Stamp

If your antique silver technique is truly sterling silver and not simply plated, it will be stamped with a telltale hallmark. Typically found on the bottom of the piece, a silver stamp may include:

• The words “Sterling Silver’
• A numeric value (800, 900, 925, etc.)
• A lion hallmark

If you notice a stamp on your antique silver, use a magnifying glass to inspect it closely. International sellers commonly use the numeric values, as they will indicate the percentage of fine silver that is found in the piece. For example, a piece stamped with 925 will indicate that the item is 92.5% silver.

If your antique silver doesn’t have a stamp, you should be leery about its silver content. It may have simply been produced in a country that doesn’t stamp its solid silver products, but you should follow up with an additional test.

Perform the Magnet Test

A strong magnet can be a good tool in determining whether your silver antique is solid silver or plated. Silver exhibits weak magnetic effects, so if you hold a magnet up and it sticks to the piece strongly, you can feel pretty confident that the piece isn’t silver. Similarly, if the magnet doesn’t stick, you shouldn’t automatically assume that you’ve got the real deal. There are plenty of materials that resemble silver and are not magnetic.

Use Some Ice

Another great way to test whether or not you own a solid silver piece can be performed with something that is probably already in your freezer – ice cubes. Silver is an excellent conductor, meaning it relays heat and cold quickly. Put some ice on or inside of your silver item, depending on what it is, and wait to see if it gets cold. Sterling silver items should be cold in less than a minute. This is an especially helpful method when you have two items that you can compare, such as a sterling silver spoon and a spoon from a silver plated set.

Get Your Piece Evaluated

If you still aren’t sure about whether or not your antique is solid silver or silver plated, there are a variety of great professionals out there that can give you some insight. An antique dealer, auctioneer, appraiser, or estate sale company should be able to examine your item and tell you about its silver composition.
