How Much is My Ring Worth? Calculate the Value of a Diamond Ring


Modern society has placed A LOT of emphasis on the value of diamond rings. The diamond ring a man buys his fiancé says a lot not only about his financial possibilities, but also about his style and tastes and how well he knows his future wire. The value of diamond ring extends far beyond sheer monetary value—it’s as much a status symbol as a fancy car or beautiful house.

If you’re looking at your diamond ring and thinking “How much is my ring worth?” you’ve come to the right place! Here, we’ll teach you how to find the value of a ring—any wedding ring or band—using a few simple principles. That means not only estimating the value of the gemstone itself, but the band as well.

By the end of this article, you’ll be ready to take your band to any jeweler’s and understand what they say when they talk about the various aspects of ring valuation.

How Much is My Ring Worth:
The Stone



The most important part of any diamond ring is, of course, the diamond!

The diamond was the most expensive part of the ring, hence the primary source of its value.



To determine the value of the stone, you need to take into account the 4 C’s:

  • Cut

    The most common cut types are round, oval, marquis, and princess. However, there are unique cuts specific to certain jewelers, or even cuts unique to certain pieces. The more unique (and beautiful) the cut, the higher the value of the gemstone.

  • Carat

    The carat determines the size of the diamond. A cheap diamond will usually be in the ½ to 1-carat size, whereas diamonds of higher carats will be more expensive. The larger stones will definitely cost more, making your ring more valuable.

  • Color

    The diamond may look perfectly crystalline, but almost all diamonds have some small element of color—usually a bit of yellow, blue, or, if you’re very lucky, pink. The color will affect the price of the stone.

  • Clarity

    Flecks, cracks, dark smudges, and other imperfections are naturally-occurring, and are simply part of the diamond. However, they will often decrease the value of the diamond, making the ring worth less.

The most common cut types are round, oval, marquis, and princess. However, there are unique cuts specific to certain jewelers, or even cuts unique to certain pieces. The more unique (and beautiful) the cut, the higher the value of the gemstone.

These are the four most important elements to consider when trying to determine the value of diamond ring. However, there are a couple of other factors to take into account, such as:

  • Settings

    Antique settings can make the diamond ring more valuable than modern settings. The setting will often make it clear how old (antique) a ring is. The older the ring, the more valuable (in most cases).

  • Condition

    A diamond in pristine condition will be worth more than one that is dented, chipped, or scratched. Of course, it’s VERY unlikely that a diamond can be damaged in daily use, but it’s vital that you give the diamond a thorough examination to ensure it’s in perfect condition.

The truth is that you can’t determine the value of your gemstone on your own. You have to take it to jeweler to get it valued.

Thankfully, our jewelers at Twery’s are happy to do the valuation for you, giving you a clear idea of how much the diamond in your ring is worth.

How Much is My Ring Worth:
The Band

Twery’s The value of your ring isn’t only determined by the stone, but the band also raises the value of the ring. After all, it’s made of gold (white, rose, or yellow), platinum, or silver, all of which are precious metals.

The costlier the metal and the more pure the metal, the higher price of the band.

When evaluating the value of a gold ring, the first thing to evaluate is the purity of the gold.

This is usually denoted by the hallmark, or the number etched into the metal of the ring. The number will usually range between 9K (very low-grade quality) and 24K (pure gold). Most wedding rings will be between 18K and 22K.

Note: Gold is very malleable, so other metals are mixed in to make the jewelry strong enough to survive daily use. 24K jewelry is very uncommon due to the fact that it bends easily.

If you’ve got a platinum ring, the hallmark will read 900PT, PT900, or 900Plat. This shows that the ring is 90% platinum—a VERY valuable ring. Of course, the lower-grade platinum rings will have a lower platinum content, thus a lower number etched into the metal.

To find the hallmark, you may need a loupe, a special magnifying glass used by jewelers. The hallmark is usually tiny, and difficult to see even with a regular magnifying glass. Once you’ve found the hallmark, it’s fairly easy to calculate the value of the band:

Step 1: Calculate the gold content

Take the hallmark number (let’s say 18K for this example) and divide the number by 24 (for 24K, or pure gold). 18 divided by 24 is 0.75. This means the 18K ring is made up of 75% gold (25% other metals).

Step 2: Weigh the ring

Gold is sold by weight (ounces or grams). You’ll need a very precise jeweler’s scale to weigh the ring.

Step 3: Multiply weight by gold content

In this example, let’s say you’ve got a ring that weighs 4 ounces. You know the ring is 75% gold, so you multiply 8 by 75%. The result: 3 ounces of pure gold.

Step 4: Multiply gold weight by price

The price of gold is always changing, so the results you get will differ from day to day. For this example, we’ll take today’s Gold Price: $1259.09. Multiply that by 3, and you get 3777.27. Your 18K ring would be worth close to $3,800.

Note: If there is a gemstone set into the ring, it can make the calculations a bit more difficult. You’ll have to subtract the weight of the stone and setting from the band.

To get the value of your ring, our experts at Twery’s add the value of the gemstone to the value of the band. But we also evaluate the style, workmanship, and condition of the ring. This is especially true of rings that have been worn (used). The use will lower the value of the ring depending on the amount of wear and damage.

If you’re trying to figure out how to find the value of a diamond ring, we recommend working with a professional appraisal service. Twery’s specialists will perform tests to determine not only the size and weight of your ring, but also the quality of the metal and stone. Our tests are 100% accurate and safe, and they are the best option for finding out the EXACT value of your ring.

We believe that it’s important to appraise your diamond ring. Not only will it help your insurance company know exactly how much it’s worth (to insure), but it will also tell you what to expect should you plan to sell it down the line. It’s good to be aware of the value of your jewelry, as that will prevent you from being “taken for a ride” by a less-than scrupulous jeweler.

Remember, when it comes to assessing the diamond ring’s value, you have to assess the value of both the stone (using the 4 C’s) and the band (using the gold content and current price).
