Why Are Diamonds So Expensive?

November 29, 2023

Diamonds may be a girl's best friend, but that friendship can come at a high cost. Is the relationship worth it? Absolutely! While people and relationships are mortal, diamonds are enduring, nearly impossible to destroy, and can be passed down over generations, increasing in both sentimental and financial value. Many beautiful things cost money, but many consumers wonder why diamonds are so expensive.

Diamonds are often considered the epitome of luxury in the world of gemstones, leading many to wonder: Why are diamonds so expensive? Their value stems from several key factors that make diamonds so valuable.

Firstly, the formation process of diamonds contributes significantly to their value. Unlike other gemstones, diamonds are formed over millions of years under extreme pressure and heat deep within the Earth’s crust. This long, natural process of creation adds to their rarity and allure.

Another crucial factor is the quality and carat weight of the diamond. Diamonds are priced per carat, and the cost can increase dramatically with the size of the stone. Larger, high-quality diamonds are rarer, making them significantly more expensive.

Furthermore, the diamond market itself plays a vital role in the pricing of these gemstones. The supply of diamonds has historically been tightly controlled by a few major companies, which has kept prices high. Additionally, marketing campaigns over the years have successfully positioned diamonds as symbols of wealth, love, and commitment, further driving their demand and value.


How is the Diamond Market?

The diamond market has captivated people for years, not just because of the allure of diamonds but also due to the high prices they command. Understanding why diamonds, particularly expensive diamonds, are so costly requires an exploration of several facets of this market. The rarity, the intricate process of mining, and the significant demand all contribute to the high value of these precious stones.

One primary reason diamonds are expensive is their formation process. Diamonds are formed over millions of years under extreme pressure and heat deep within the Earth’s crust. This long formation period, coupled with the challenging mining process, contributes significantly to the rarity and cost of diamonds.

Another factor influencing diamond prices is carat weight. Diamonds are priced per carat, and the price increases exponentially with the carat size due to the rarity of larger diamonds. This pricing structure makes acquiring a larger, high-quality diamond a notably expensive endeavor.

The diamond supply chain also plays a crucial role. Historically, the diamond market has been tightly controlled, with a few major players influencing the diamond supply. This control over supply has traditionally kept diamond prices high. However, the emergence of the lab diamond has introduced a new dynamic. These lab-created diamonds, which mimic the properties of natural diamonds, offer a less expensive alternative, challenging the traditional diamond market.

Marketing campaigns have significantly impacted the high demand for diamonds. These campaigns have successfully ingrained diamonds as a symbol of luxury and status, further driving the demand for diamonds.

In conclusion, the diamond market is shaped by a combination of factors, including the natural formation process, carat weight, controlled supply, and effective marketing strategies. All these elements contribute to the high cost of diamonds and the continuous demand for these precious stones, making them a valuable and sought-after commodity in the global market.


The De Beers Myth

The legendary De Beers Mine is at the heart of the diamond industry's history. Established in 1888 by Cecil Rhodes in South Africa, De Beers once held a formidable 80-85% monopoly over the global rough diamond distribution. This dominance allowed De Beers to control the prices of diamonds - by strategically purchasing and stockpiling diamonds, De Beers limited supply, creating an artificial scarcity that drove up their value.

However, as more countries entered the diamond-mining arena and new mine discoveries were made, the market began to fragment. By 2019, De Beers' market share had diminished to about 30%, a far cry from its once-dominant position. The decrease in market control highlights the changing landscape of the diamond industry and dispels the myth that a single entity can dictate global diamond prices in modern times.


How Rare Are Diamonds?

In the early 1800s, diamonds were indeed a rare and exclusive commodity, primarily found in India and Brazil. The diamond landscape underwent a seismic shift when De Beers started discovering mines in South Africa, flooding the market with diamonds. Today, diamonds are mined in over 30 countries, with major producers including Russia, Botswana, Canada, the Democratic Republic of Congo, and South Africa.

An average of 134 million carats are mined yearly, which hardly makes diamonds scarce. However, only 20-30% of these diamonds are of gem quality and find their way into diamond jewelry pieces; the rest are used for industrial purposes. That means extremely high-quality diamonds, such as those graded as flawless D color stones are so rare that many jewelers never even get to handle them. Many more diamonds with slightly lower grades are available, giving consumers access to more choices and diamonds that still reflect a great deal of sparkle.


The True Costs of a Diamond

While supply and demand play a role in diamond prices, several other factors contribute significantly to their price tag.

Mining Costs Are High:

Where Are Diamonds Found? The quest to locate diamond deposits takes us to very few places on Earth. These locations are among the only areas where the quantity of diamonds is sufficient for mining operations, which underscores the rarity and preciousness of earth-mined diamonds. Mining companies allocate substantial investments to unearth these gemstones when they discover viable deposits. The scarcity of such mined diamonds contributes to their mystique and high value, making the discovery of these locations all the more significant in the diamond industry.

Many diamond-rich sites are located in some of the world's most remote and inaccessible areas. For example, significant deposits can be found in the Canadian Tundra, where the harsh climate poses unique challenges. Similarly, diamonds from the earth are also extracted from the ocean floor off Namibia's coast, requiring advanced marine technology for underwater mining. The deserts of Botswana are another notable source of earth-mined diamonds, where extreme conditions demand robust and specialized equipment.

The mining process is slow and laborious, with miners often needing to excavate over 200 tons of rock to uncover a single carat of diamond, which may not even be of gem quality. This arduous process contributes significantly to the overall expense of diamond production.

Diamond Yield Is Low:

What is extracted from mines is considered rough, and the actual diamond yield is much smaller. On average, a one-carat rough diamond will yield only a third-carat polished diamond. In the cutting and polishing process, round diamonds lose the most rough, which is one reason they cost more than fancy-shaped diamonds, such as oval or princess cuts.

No matter how a rough diamond is cut or divided, most of the mined carats end up as dust from the cutting and polishing processes. The transformation from rough diamond to finished stone can take hours, days, or even weeks as expensive experts meticulously determine the best way to extract the most value from each rough diamond.

The Grading Process:

The final piece of the production puzzle is left to a diamond grading institute such as the Gemological Institute of America (GIA). A gemologist will inspect, weigh, and grade each diamond, carefully evaluating its cut, color, and clarity and issuing it a certificate. Each step in the diamond pipeline requires substantial capital and financing, which can only be recouped once the stone finally makes it into a piece of diamond jewelry and is sold.


Ethical and Environmental Considerations

In years past, the diamond industry has faced scrutiny for unethical labor practices and environmental degradation; however, in recent decades, consumers have become increasingly conscious of the ethical and ecological impact of their gemstone purchases. 

Many consumers seek gemstones with certifications like the Kimberley Process, which aims to prevent the trade of conflict diamonds or blood diamonds. Responsible mining practices, while adding to production costs, are viewed as essential investments that align with consumers' values.


Market Trends and Influences on Diamond Prices

The diamond market is dynamic and subject to various factors influencing prices. Economic conditions like the 2008 economic downturn and the recent COVID-19 pandemic have impacted the diamond market. Global events and changes in consumer preferences also play crucial roles.

Celebrity endorsements and jewelry trends can drive consumer interest in specific diamond shapes, affecting demand and subsequently influencing prices. The dynamic nature of the market underscores the complexity of diamond pricing and the importance of staying attuned to shifts in trends and economic conditions.


Why Diamonds so Expensive: Fancy Color Diamonds

Beyond the traditional colorless diamonds, fancy color diamonds have gained immense popularity, especially in the realms of engagement rings and high-end jewelry. These unique diamonds make for a distinctive choice for a diamond engagement ring, offering a splash of color and exclusivity that stands out in any jewelry case.

Colored diamonds, representing just 0.01% of diamonds mined globally, highlight their exceptional rarity. Among them, blue, green, and pink diamonds are particularly scarce, which translates into a higher price point, making them a luxurious choice for an extraordinary diamond engagement. These colors are often the centerpiece of high-end jewelry pieces, coveted for their uniqueness and beauty.

Conversely, yellow and brown diamonds, while still rare, are more commonly found. They offer a more accessible entry point into the world of colored diamonds, making them popular choices for diamond engagement rings for those seeking both uniqueness and affordability. Their warm hues provide a rich depth to any jewelry design, making them a favorite in the jewelry case for those who desire a touch of color in their engagement rings.

The question "Are Diamonds a Good Investment?" often arises when considering the factors that contribute to diamond prices. These factors are multifaceted, reflecting a complex interplay of historical significance, the challenges and costs associated with mining, the rarity of high-yield deposits, stringent grading processes, ethical sourcing considerations, and the ever-shifting dynamics of the global market.

Despite their high expense, diamonds have proven to be stable investments over the decades, often retaining or increasing in value. Beyond their emotional value, diamonds represent a significant purchase that can transcend mere adornment. A diamond ring, often seen as a symbol of enduring love, is also an investment that withstands economic fluctuations, holding its value over time and becoming a treasured heirloom for future generations.
