Diamonds are often considered one of the world's most valuable and sought-after gemstones. Among the various types of diamonds, yellow diamonds are particularly intriguing due to their unique and captivating beauty. 

But how much are yellow diamonds worth

Understanding the true value of these gems can be a complex and multifaceted task, as it depends on several factors that affect their rarity, quality, and market demand

In this blog, we will dive into the world of yellow diamonds and explore the key factors that determine their worth. 

Understanding The Rarity Of Yellow Diamonds

Understanding the rarity of yellow diamonds is an essential aspect of determining their value, as it affects their market demand and availability. 

Here, we will explore the formation process of yellow diamonds, compare them with other coloured diamonds, and examine their rarity and availability.

Formation Process 

Like all natural diamonds, yellow diamonds are formed beneath the earth's surface under high temperature and pressure conditions. However, the specific process that creates the yellow colouration in diamonds is still not fully understood. 

It is believed that nitrogen atoms trapped inside the diamond crystal lattice during the formation process are responsible for the yellow hue. The more nitrogen atoms present, the more intense the yellow colour will be.

The formation process of yellow diamonds is similar to other coloured diamonds, such as pink, blue, and green diamonds. However, the specific conditions required for forming yellow diamonds are less understood, making them more challenging to find and mine.

Comparison With Other Colored Diamonds

Yellow diamonds are part of the coloured diamond family, which includes diamonds that exhibit a range of hues, from pink, blue, green, red, and orange, among others. 

Compared to other coloured diamonds, yellow diamonds are less rare than pink, blue, and red diamonds but more challenging to find than brown diamonds. This makes yellow diamonds a unique variety in the coloured diamond world.

Yellow diamonds also come in various intensities, from faint yellow to fancy vivid yellow. The more intense the colour, the rarer and more valuable the diamond becomes. The most valuable yellow diamonds are those with a pure yellow hue, without any secondary hues such as green, brown, or orange.

Rarity And Availability 

Yellow diamonds are among the rarest coloured diamonds, accounting for less than 1% of all diamonds mined worldwide. Most yellow diamonds are found in mines in Australia, South Africa, and Russia, although some have been discovered in other locations worldwide.

The rarity of yellow diamonds is also affected by their size and quality. Larger and higher-quality yellow diamonds are much rarer than smaller, lower-quality ones. As a result, these diamonds command a higher price in the market.

Regarding availability, yellow diamonds are not as widely available as white diamonds. 

However, they are more commonly found than other coloured diamonds, such as pink, blue, and red. Yellow diamonds are also more readily available than rare gemstones, such as alexandrite, emerald, and ruby.

Evaluating The Quality Of Yellow Diamonds

Evaluating Of Yellow Diamonds

When evaluating the quality of yellow diamonds, there are four key factors: colour, clarity, cut, and carat weight. These factors are collectively known as the 4Cs of diamond grading and play a crucial role in determining the value of yellow diamonds.


The colour of a yellow diamond is the most important factor in determining its value. The more intense and pure the yellow colour, the more valuable the diamond is. 

The Gemological Institute of America (GIA) grades yellow diamonds on a scale from faint yellow to fancy vivid yellow, with the latter being the most valuable. Yellow diamonds with secondary colours, such as green, brown, or orange, are less valuable than those with a pure yellow hue.


The clarity of a yellow diamond refers to the number, size, and location of inclusions or blemishes within the diamond. Inclusions are natural imperfections during the diamond's formation process, while blemishes are external flaws caused by the cutting and polishing process. 

The fewer inclusions and blemishes a yellow diamond has, the more valuable it is. The GIA grades diamond clarity on a scale from Flawless to Included, with Flawless being the most valuable.


The cut of a yellow diamond refers to the angles and proportions of the diamond's facets, which affect how light is reflected and refracted within the stone. A well-cut yellow diamond will have superior brilliance, fire, and scintillation, making it more valuable than a poorly cut diamond. 

The GIA grades diamond cut on a scale from Excellent to Poor, with Excellent being the most valuable.

Carat Weight

The carat weight of a yellow diamond refers to its size and weight, with one carat equaling 0.2 grams. Larger yellow diamonds are rarer and more valuable than smaller ones, all other factors being equal. 

However, the value of a yellow diamond increases exponentially with its size, meaning that a 2-carat yellow diamond is worth more than twice as much as a 1-carat diamond of the same quality.

Pricing Yellow Diamonds

When it comes to pricing yellow diamonds, several factors can affect their value, including their colour, clarity, cut, and carat weight, as mentioned above. Market demand, supply, and other economic factors also play a role in determining the price of yellow diamonds.

Factors That Affect The Price Of Yellow Diamonds

Aside from the 4Cs, several other factors can affect the price of yellow diamonds. One of the primary factors is market demand

The prices tend to rise when there is a high demand for yellow diamonds.

Conversely, when the market demand for yellow diamonds is low, the prices may drop.

Another factor that can affect the price of yellow diamonds is the diamond's rarity. Yellow diamonds are relatively rare, which means they may be more expensive than other diamonds of similar quality. 

The diamond's size and shape can also influence the price. Larger yellow diamonds are generally more valuable than smaller ones.

Comparison Of Yellow Diamond Prices With Other Types of Diamonds

Yellow diamonds are generally more expensive than white diamonds due to their rarity and unique colour. 

However, other coloured diamonds, such as pink and blue, can be even more valuable than yellow ones. For example, the Pink Star diamond, a 59.60-carat fancy vivid pink diamond, sold for a record-breaking $71.2 million in 2017.

Conclusion: How Much Are Yellow Diamonds Worth?

In conclusion, yellow diamonds are a stunning and unique gemstone that is highly sought after by collectors and enthusiasts. Their rarity and beauty make them valuable, with prices determined by various factors such as colour, clarity, cut, carat weight, market demand, and rarity. When evaluating the value of yellow diamonds, it is crucial to consider each factor to determine a fair price. 

Whether you're looking to buy, sell, or admire yellow diamonds, understanding their true value is key to making informed decisions and appreciating their beauty.


What is the average price range for yellow diamonds?

Generally, the price range for a high-quality yellow diamond can range from several thousand to several hundred thousand dollars per carat. However, lower quality or smaller yellow diamonds may be available for less.

Are there any famous yellow diamonds, and how much are they worth?

Yes, several famous yellow diamonds have gained worldwide recognition. 

For example, the Tiffany Yellow Diamond, one of the world's largest yellow diamonds, is estimated to be worth over $30 million.

Other famous yellow diamonds include the Incomparable Diamond, the Graff Vivid Yellow, and the Allnatt Diamond.

Is it essential to get a GIA certificate when buying a yellow diamond?

When buying a yellow diamond or any other diamond, getting a GIA (Gemological Institute of America) certificate is essential. The GIA is a trusted and respected organisation that objectively and objectively assesses a diamond's quality based on the 4Cs (colour, clarity, cut, and carat weight). 

A GIA certificate ensures you get what you paid for and can help protect you from purchasing a diamond that is artificially enhanced or treated.
