How much is a 0.25 carat diamond ring worth? Here is the short answer: it is worth between $275 and $440.

Here is the long answer: the price of a 0.25 carat diamond ring is subject to certain factors. The same applies to all types of diamonds.

Valuing a diamond ring is not such a straight forward task. There are some things to take into consideration. This is because they greatly affect whether or not the diamond has any value.

Factors Affecting the Value of Diamond

Let me explain the important factors that affect how valuable a diamond is.

There are, of course, the 4 Cs that come first. Keep them in mind when you want to buy, sell or simply value your diamond:

  • Clarity
  • Cut
  • Carat
  • Color
  • Shape
  • Fluorescence

Then, there is the Rapaport Report that is published every Thursday at midnight. It shows the current cost of diamond.

Then, there is the certification from American gem Society or Gemological Institute of America.



This is the least important of the 4 Cs I will talk about. This is because clarity is usually not visible to the untrained eye.

So if you are not particular about flaws and blemishes, you should not even consider this factor.

In truth, your diamond ring is not going to be rejected or valued less if it has internal flaws. Just consider it an extra point that only comes into play for meticulous jewelers.

A diamond could have surface or internal flaws. And for a surface flaw to be considered, it needs to be visible under 10x magnification.


I’m sure you are thinking shape but cut does not mean that. It means polish, symmetry and proportion.

When a diamond is freshly mined, it lacks luster. It has nothing to draw you to it, except the knowledge that it is diamond.

But you begin to appreciate it when it is cut. The sparkles and light reflection will bounce off of it beautifully.

Now, if your diamond is not cut well, it will still reflect light but it won’t look so great. Place it side by side beside a better cut diamond and it will look dull.

In other words, the cut of the diamond should be the first factor you consider when valuing it.

With a great cut, you can throw out one or more of the other Cs. This is because once a diamond looks beautiful, shine and pattern, little else matters.


You thought this was the most important factor in the general sense, right? Not exactly but it depends on who is looking.

Carat means the weight or size of the diamond and is the most visible factor. A carat equals 0.2grams.

So the weight of your diamond, which is part of what affects its value, is about 0.05grams. This is way less than the weight of a paper clip.

If you are not sure, this video shows what a 0.25 carat diamond looks like…

Interestingly, though, this factor affects the value or price. Sadly, you cannot do anything about it. Once it is cut, it is cut and you get what you pay for.

The higher the carat of a diamond, the higher the price, and sometimes, the difference in price is just ridiculous.

For example, you may find a 0.4 carat diamond is close to half the price of one that is 0.5 carat.

Why? It is harder to find materials for larger carats. So the price increases in leaps and bounds.

An interesting fact: if the carat of a diamond is just under a whole number, the price difference won’t be much.

So if you want to value a 0.9 carat and 1 carat diamonds, the difference may be just about $1,000. But to the naked eye, is there any difference? No difference.



This factor has an effect on the price and beauty of a diamond, though not as much as cut or clarity.

The color of a diamond means a tint in the gemstone, usually yellowish. The range of the color goes from D, which is totally colorless, to Z, which is a clear brown/yellow tint.

If your diamond has a tint, no matter how little, it will affect the value. This is because colorless diamonds are really rare. So, they are sold at a premium. And the value goes downwards the more color the diamond has.

The price difference between two diamonds of the same cut, carat and clarity but of different colors can be as much as $3,500. Mind boggling, right?

Therefore, check your diamond. Does it have any color to it? This should give you an idea of how much worth it has.



If the diamond on your ring is round, then you may get good value for it. This is because round diamonds cost more than other shapes in diamonds.

Other shapes in diamonds have their value. And being able to identify each one will help you recognize its value:

Princess Cut

Diamonds with a princess cut has some value. They come second to round diamonds. This is because they come out sparkly, almost the same as the round ones.

Marquise Cut

This is fancy and draws attention. But it does not attract as much value as the previous cuts. However, it tends to look bigger than other cuts, even the round ones. The same is true for a pear cut.

Oval Cut

This elegant and modern. And because of its closeness to the round shape, it attracts good value.

Other shapes include step cut and rectangular or square cuts. While they look sophisticated and beautiful, they may not fetch a good price.


When diamond has a slight glow when put under blue UV light, it is considered to have fluorescence.

Some minerals that infuse themselves into the diamond cause this glow. It is completely natural and does not appear in all diamonds.

However, despite the fact that it is natural and does not affect the gemstone in any negative way, it is seen as bad. In other words, it is seen as devaluing the diamond.

There is an upside to this. If your diamond has some color, that little glow or fluorescence masks it. That is it improves the color, making it look more colorless than it actually is.

Therefore, if you are buying, you may diamond with fluorescence cheaper than its normal price. And if you are selling your colored diamond, fluorescence masks the color and gives it more value.


Your diamond ring would have more value if it has been certified. In fact, it is so important that you certify that you can consider it one of the Cs.

There are few reliable certification labs but the American Gem Society (AGS) and the Gemological Institute of America (GIA) are the most reliable. They are known and trusted around the world. And if your stone carries their verifiable certification, it increases it value.

Rapaport Report

The report that comes in from Rapaport every Thursday night lists the prices of different diamond grades.

The report usually looks so simple. But it may not be wise to rely on it when valuing your diamond for the following reasons:

  • Two same-grade diamonds may have different prices. Placed under different fluorescent lights, one may look hazy while the other looks bright and clear. And naturally, the clear one sells higher.
  • Cut does not matter in their pricing. Due to the fact that cut affects how much a diamond sells, not taking it into consideration affects the reliability of the report’s pricing. It considers only the clarity, color and carat.
  • The listed prices are usually the highest ones. Using the report to value your diamond may play to your advantage or not.

Will the Value of the Diamond Ring Increase with Time?

The value may increase with time but don’t count on it. In fact, the minute you buy a diamond is the minute the value starts decreasing. This means the market for reselling is not strong.

However, if you are looking at it from the investment angle, you may make some profit.

Data shows that there is about 4% increase, on the average, in the price of diamond every year. Seemingly, it keeps in line with the country’s inflation.

These factors affect the value of your 0.25 carat diamond ring has. It is also important to bear in mind that the jeweler or valuer is important.


The worth of your diamond ring depends on the following:

  • Clarity
  • Cut
  • Carat
  • Color
  • Shape
  • Fluorescence
  • Rapaport Report
  • Certification

However, if it has the right cut and is colorless, the other Cs may not play a major role. Add proper certification, lack of fluorescence and a round shape and you have hit a jackpot.

But don’t despair even if it does not meet all these factors. The value may appreciate with time.
