kid checking for diamond value

Diamonds have always held an allure that is hard to resist. They are the epitome of luxury and elegance, and their beauty is unmatched. But have you asked yourself how much your precious diamond is worth?

A diamond’s valuation involves more factors beyond just its carat weight. From cut, clarity, and color to market demand and the latest industry trends, many variables can influence the value of your diamond.

As a diamond jewelry company with over 20 years of experience, we’ve seen and worked with every possible diamond type. In this article, we’ll unveil the mysteries of diamond valuation, explaining the factors that determine the value of a diamond. I will give you a comprehensive guide on how to choose the true worth of your precious gem.

Whether you’re a diamond collector, a jewelry enthusiast, or simply curious about the world of diamond valuation, this article is a must-read for you. So, dive with us into this fascinating world.


Factors that Affect Diamond Value

A diamond’s value is determined by several factors, including its cut, clarity, color, and carat weight. These factors work together to determine the overall quality of the diamond, which in turn affects its value. The cut of a diamond is, without any doubt, the most critical factor in determining its value. A well-cut diamond will always have more sparkle and fire and be more valuable than a poorly-cut diamond.

The clarity of a diamond is very important, as it refers to the number and size of inclusions and/or blemishes on the diamond’s surface. The diamond is more valuable if it has fewer inclusions.

The color of a diamond is another important factor, with diamonds graded on a scale from D (colorless) to Z (yellow). The closer diamonds are to being colorless, then the more valuable they are. Finally, the carat weight of a diamond is a measure of its size, with larger diamonds being more valuable than smaller ones.


Comprehending  the 4Cs of Diamond Grading

To understand diamond grading, we need to consider the 4Cs: cut, clarity, color, and carat weight. These factors are crucial in determining a diamond’s quality and value. Let’s explore each of these factors in more detail.

Diamond Cut:

This refers to a diamond’s symmetry, proportions, and polish. If a diamond is well-cut then it will have more sparkle and fire, increasing its value. Conversely, a poorly cut diamond will have less brilliance and appear dull.

Diamond Clarity:

The clarity refers to the number and size of inclusions or blemishes on the diamond’s surface. Fewer inclusions indicate higher clarity, and therefore a more valuable diamond.

Diamond Color:

There is a color scale to grade diamonds ranging from D (colorless) to Z (yellow). A diamond’s value increases as it gets closer to being colorless.

Diamond Carat Weight:

The carat weight is a measure of a diamond’s size, with larger diamonds being more valuable than smaller ones. A higher carat weight not necessarily mean a better diamond, however, as the other three Cs also play a big role in determining value.

The Importance of Diamond Certification

When it comes to diamond valuation, certification is critical. A diamond certification is an official document that analyzes a diamond’s quality, including its cut, clarity, color, and carat weight. Therefore, it is vital to ensure that your diamond is certified by a reputable organization. One like the Gemological Institute of America. A certified diamond will be more valuable than an uncertified one, as it assures its quality and authenticity.

For further reading, we covered the 5 C’s of a diamond on another article in our site.

Evaluating Diamond Cut

As we mentioned earlier, the cut of a diamond is the most crucial factor in determining its value. A diamond that is well-cut will have a greater degree of sparkle and fire, thus increasing its value compared to a poorly cut diamond. Proportions, symmetry, and polish determine the cut of a diamond. A diamond with ideal proportions will reflect the lightest and be valuable. The balance of a diamond refers to the alignment of its facets, while the polish refers to the smoothness of its surface. A diamond with excellent symmetry and polish will be more valuable than one with poor symmetry or polish.

Evaluating Diamond Clarity

The clarity of a diamond indicates the number and size of inclusions and/or blemishes on the diamond’s surface. Diamonds are evaluated based on the presence of internal and external flaws, which are referred to as inclusions and blemishes, respectively. The fewer the inclusions and blemishes, the more valuable the diamond. The grading system for diamonds ranges from Flawless, which means no inclusions or blemishes are visible under 10x magnification, to Included, which indicates the presence of inclusions or blemishes visible to the naked eye. A diamond with a higher clarity grade is more valuable than one with a lower clarity grade.

Evaluating Diamond Color

Other important factor in determining a diamond’s value is its color. Diamonds are graded from D (colorless diamonds) to Z (yellow diamonds). The closer a diamond is to be colorless (grade D), the more valuable it is. Diamonds can also come in other colors, such as pink, blue, and yellow, known as fancy color diamonds. These diamonds are valued based on the intensity and rarity of their color.

Evaluating Diamond Carat Weight

The carat weight of a diamond is a measure of its size. One carat equals 0.2 grams, and diamonds can come in various sizes, from less than one carat to several. Usually, larger diamonds are more valuable than smaller ones, as they are rarer and more difficult to find.

Carat weight should be one of many factors considered when you are valuing a diamond. For example, a smaller diamond with excellent cut, clarity, as well as color can be more valuable than a larger diamond with poorer quality.

Evaluating a Diamond Ring

When evaluating the price of a diamond ring (a diamond engagement ring, for example), multiple factors contribute to its overall value. As we mentioned above: the diamond’s cut, color, clarity, and carat weight, all affect its price. The cut affects the diamond’s brilliance, color grades range from colorless to light yellow, clarity grades determine the presence of inclusions or blemishes, and carat weight determines size and rarity. Considering the interplay of these factors, along with the material of the ring (white/rose/yellow gold, platinum or other) and additional aspects like diamond shape, fluorescence, and certification from reputable labs is crucial. If you’re seeking to buy an engagement or wedding rings, a professional appraisal from a trusted jeweler is recommended. Working with  a diamond designer ensures a fair and accurate valuation of the entire ring, along with a costumed design to match you budget, taking into account unique ness high value.

How to Get Your Diamond Appraised

If you want to know the actual value of your diamond, it is essential to have it appraised by a professional. An appraiser will examine your diamond and provide a detailed report of its quality and value. Therefore, it is essential to choose an appraiser who is certified and experienced in diamond appraisal. You can find a list of certified appraisers on the websites of organizations like the National Association of Jewelry Appraisers (NAJA) and/or the American Gem Society (AGS).

Once you’ve found a certified appraiser, schedule an appointment to evaluate your diamond. During the appraisal process, the appraiser will examine your diamond using specialized equipment and techniques to determine its cut, clarity, color, carat weight, and other factors that affect its value. Upon completing the appraisal process, the appraiser will furnish you with a comprehensive report detailing the value of your diamond.

Remember that the appraisal report needs to be updated every now and then to reflect any changes in the diamond’s value. An updated appraisal report will be necessary if you plan to sell your diamond or insure it.

Selling Your Diamond: Tips and Considerations

Selling a diamond can be daunting, but it can be a smooth and profitable process with the proper knowledge and approach. If you want to sell a diamond, there are a few things to remember:

Know the value of the diamond: Before you sell it, it’s essential to understand its true value. It is crucial to have your diamond appraised by a professional to determine its actual value; otherwise, you can research the market value of similar diamonds.

Be realistic about your price: While you may have an emotional attachment to your diamond, buyers will not be willing to pay an inflated price. Know the actual value of your diamond and set a reasonable asking price. Be prepared to negotiate, as the price may differ from what you hoped.

Consider getting a grading report: A grading report from a reputable grading agency like the GIA can provide buyers with an objective evaluation of your diamond’s quality.

Be cautious of scams: Unfortunately, the diamond industry is prone to scams and frauds. Be cautious of potential buyers who offer to pay significantly more than the market value or ask for payment upfront.

Negotiate carefully: When negotiating with potential buyers, be firm but flexible. Don’t hesitate to withdraw from a deal if you feel uncomfortable or undervalued.

Wait for the best moment: It’s important to keep in mind that the diamond market can be unpredictable. It might be very wise to wait for the optimal time to sell


Selling a diamond requires careful consideration and research. Knowing the value of your diamond, deciding where to sell it, presenting it in the best light, and negotiating carefully are all essential steps to ensure a successful sale. Follow these tips and you can maximize the value of your diamond and sell it with confidence.

Find Your Size & Ring Match with Our Guide Size Chart

If you would like to measure your ring size immediately the quickest ways and with an accurate fit – you can do it with our Ring Size Chart here.

The way to quickly get your measurements is either going to the nearest jewelry shop and ask them to measure you, or to buy a Ring Sizer Measuring Gauge with a 2-day delivery to the US!
Then you can match your measurement to the size chart below to get your exact ring size.

A few factors we recommend to consider for the perfect measure:

  1. First, it’s important to measure the exact finger of the specific person you’re buying the ring for.
    We all have different measurments & each finger is unique. Measuring right will spare future gaps.
  2. It’s best to measure the finger at the end of the day, when it is at its largest, as fingers tend to swell in the heat.
    It’s also a good idea to measure the finger at least a few times to ensure an accurate measurement.
    For best results: measure at different times of the day and under different conditions (e.g. hot, cold, humid…)
  3. In addition to finger size, you should also consider  the wearer’s personal preference. Some prefer a snug fit, while others like it looser.
    Find the perfect balance: A comfortable wear that doesn’t easily slip off.
    Consider the width of the ring as well: A wider ring will need to be a slightly larger size to fit comfortably on the finger.
    Consider the style of the ring: Some styles are narrow & delicate and therefore snugly, while others are chunky and fit more loosely.
  4. There are a few different size systems used around the world. We gathered different international sizes to make it as easy as possible to find your right fit. Make sure you’re using the correct units!
