Collection of high quality diamonds
Diamonds hold considerable value due to their rarity, durability, and cultural significance. While market fluctuations and ethical concerns may affect their perceived worth, diamonds remain highly sought-after gemstones, cherished for their beauty and symbolism in various contexts.

Many of us have grown up with the notion that diamonds are synonymous with value, rarity, and unbreakable permanence. Our collective consciousness is dotted with phrases like 'diamonds are forever' and images of these glittering stones as the ultimate symbols of love and commitment. However, this widespread belief is worth examining in the light of both historical events and the current state of the diamond market.

When we dig into the history of diamonds, we find that their high value is a fairly recent development, heavily influenced by successful marketing rather than intrinsic rarity. Diamonds are indeed a naturally occurring mineral, but they are not as scarce as we once believed. Advancements in mining technology and the discovery of new reserves have shown that diamonds are more abundant than the diamond industry might have us think.

Considering the role of marketing campaigns, we start to see a different picture of the diamond market. The perceived value of diamonds is highly influenced by the narratives we've been told. Meanwhile, the true value of diamonds, like many other goods, is impacted by a variety of factors such as cut, clarity, carat weight, and color. Moreover, the introduction of high-quality synthetic diamonds has added a new dimension to the conversation about what diamonds are actually worth.

Historical Context of Diamonds as Valuables

In exploring the historical context of diamonds as valuables, we witness a fascinating evolution of the diamond market and the impact of strategic control over diamond supply by entities like De Beers. This section illuminates how diamonds transitioned from gemstones to coveted items of wealth and status.

Development of Diamond Market

Initially, diamonds were treasured for their unmatched hardness and brilliance. In ancient times, they were considered precious across various cultures, with some of the earliest known references originating in India. As trade routes expanded, diamonds found their way into the medieval markets of Europe where they gradually became symbols of wealth and status, particularly among the aristocracy.

The turning point for the global diamond market came in the 19th century. The discovery of diamond mines in South Africa in 1867 catalyzed a transformative increase in diamond availability. Despite their abundance, diamonds were marketed as rare to maintain their high perceived value. This was achieved by establishing a distribution chain that controlled the flow of diamonds from mine to market, ensuring that their supply remained regulated.

DeBeers and the Control of Diamond Supply

De Beers, founded in 1888, rapidly established a monopoly over the diamond industry. They effectively controlled global diamond prices through strict regulation of supply and demand. By limiting supply, De Beers ensured that the perceived rarity of diamonds was maintained, reinforcing their status as valuable and desirable.

Their control over the industry was further solidified through a historic marketing campaign in 1947, encapsulating the notion that "a diamond is forever." This slogan ingeniously linked diamonds to the concept of eternal love, ingraining diamonds as the quintessential choice for engagement rings. Consequently, we saw De Beers' influence extend beyond just the supply chain to embed diamonds deeply into social customs and consumer expectations.

Through our examination, we understand that the market value of diamonds is not solely rooted in their physical properties, but significantly shaped by market forces and the adept maneuvering of supply by monopolistic entities like De Beers.

Physical and Material Properties

Natural vs lab grown diamond


When we examine diamonds, we pay close attention to their distinct physical and material attributes. These properties not only influence a diamond's beauty and use in jewelry but also its overall value and distinction in the gemstone market.

Diamonds Under the Lens

Under close examination, diamonds reveal unique characteristics that allow us to evaluate their worth. We focus on attributes such as cut, color, and clarity — each of these contribute to a diamond's allure. The cut of a diamond refers to how well it has been shaped and faceted, directly influencing its ability to reflect light and sparkle. The color of a diamond can range from colorless to shades of yellow or brown, with colorless diamonds generally being the most valued. Clarity is determined by the presence of internal inclusions or external blemishes, with fewer imperfections signaling a higher quality diamond.

Lab-Grown Versus Natural Diamonds

The advent of lab-grown diamonds has introduced a counterpart to natural diamonds that presents similarities in physical and chemical properties. Both types of diamonds display the same extraordinary hardness, topping the Mohs scale at a hardness level of 10, which is why diamonds are renowned for their durability. However, their origins mark a significant distinction; natural diamonds are mined, whereas lab-grown diamonds are created in controlled environments. Our scrutiny of lab-grown gems is as meticulous as with natural stones, with grading systems from institutions like the Gemological Institute of America (GIA) and the American Gem Society (AGS) applied to certify their quality. These systems assess the same qualities in lab-grown diamonds as they do in natural ones to ensure a reliable standard of cut, color, and clarity.

Market Dynamics of Diamonds

In our exploration of the diamond industry, we have identified significant environmental and ethical concerns associated with diamond mining and purchasing. It is essential to consider the full scope of these impacts to make informed choices.

Impact of Diamond Mining

  • Environmental Impact: Diamond mining has considerable effects on ecosystems. Mines can result in large craters, devastate vast tracts of land, and affect local wildlife. For example, traditional mining practices may disrupt 1750 square feet of land per carat. Specifically, open-pit mines excavate extensive areas to reach the diamonds, contributing to soil erosion and deforestation. Further, it is estimated that mining one carat of diamond can result in over 100 square feet of disturbed land and nearly 6000 pounds of mineral waste.
  • Carbon Emissions and Water Use: The carbon footprint of diamond mining is also a concern; it is associated with significant CO2 emissions due to energy consumption, particularly carbon-intensive types of energy. Moreover, mining consumes vast quantities of water—about 127 gallons per carat, raising concerns about water use and pollution.
  • Industrial Diamonds and Pressure: While not all diamonds are used for jewelry, industrial diamonds are subjected to similar environmental pressures. Their production involves high-energy processes to create the extreme pressure and temperatures required to form diamonds.

Responsible Diamond Purchasing

  • Certifications and Origins: We, as purchasers, can look for certifications that assure ethical sourcing and minimizing environmental harm. There are industry certifications indicating responsibly-mined diamonds, which aim to protect local ecosystems and reduce the carbon footprint.
  • Lab-Grown Alternatives: Lab-grown diamonds present a less damaging alternative. They typically use less water and produce fewer carbon emissions per carat. In terms of land disruption, lab-created diamonds are far less impactful, theoretically using only 0.07 square feet of land per carat. These diamonds are grown under controlled conditions using advanced technologies that replicate the high pressure and temperatures found deep within the Earth.

By prioritizing responsible purchasing practices, we encourage the industry to adhere to sustainable and ethical standards, subsequently reducing our environmental impact.

The Science of Diamond Formation



In exploring the science behind diamond formation, we find a fascinating interplay of extreme conditions that transform simple carbon into a treasured, brilliant crystal. Our focus rests on the geology that facilitates the existence of natural diamonds and the meticulous human processes of cutting and shaping that enhance their allure.

Geology of Diamond Mines

Diamonds originate deep within the Earth's mantle, where temperatures soar above 1,200 degrees Celsius and the pressure reaches an immense 45 kilobars—equivalent to 45,000 times the atmospheric pressure at sea level. These conditions enable the crystallization of carbon into diamonds. Over millions of years, volcanic eruptions can bring these gems closer to the surface, where they become accessible through mining.

Most natural diamonds are found in two types of deposits:

  • Kimberlite pipes: These are volcanic pipes that push diamonds from the Earth's mantle to the surface. Named after the town of Kimberley in South Africa, where such a deposit was first discovered.
  • Alluvial deposits: These are Diamonds that have traveled from their primary kimberlite sources by natural erosive processes. They are found in riverbeds, coastlines, and ocean floors, having been carried there by water.

Diamond mining involves extracting these precious stones from the earth through various methods. Whether through open-pit mining, underground mining, or alluvial mining, each method is designed to efficiently locate and retrieve diamonds from the surrounding rocks and sediment.

Cutting and Shaping Diamonds

Once unearthed, diamonds are not immediately in the sparkling form we find in jewelry. They require the skills of expert cutters to reveal their beauty. Cutting and shaping diamonds is a delicate process, rooted in rich tradition, precision, and an intimate understanding of the crystal structure of each diamond.

The process involves:

  1. Planning: Analyzing the rough diamond to determine the best cut that maximizes size, shape, and overall quality.
  2. Cleaving or Sawing: Splitting or cutting the rough diamond into pieces more suitable for individual gemstones. Lasers are often employed for their precision.
  3. Bruting: Also known as girdling, this involves grinding two diamonds against each other to shape them into a round form.
  4. Polishing: Transforming the bruted diamond into a faceted gem involves the intricate work of polishing each facet to perfection.
  5. Inspection: A final examination ensures that the diamond meets the exacting standards of quality and brilliance.

It is during this stage that the diamond is graded by its cut, as well as its clarity, color, and carat weight—collectively known as the "Four Cs." Ourite cutting and grinding processes enhance the diamond's natural properties and prepare it to be set into a variety of jewelry pieces, ultimately determining the stone's value and desirability.
