The Birth of a Diamond: Formation and Extraction
Natural Formation
Diamonds are formed deep within the Earth’s mantle under conditions of intense heat and pressure. This process takes millions to billions of years. Carbon atoms bond in a crystal structure that creates the hardest natural substance known. These diamonds are then carried closer to the Earth’s surface through volcanic eruptions, embedded in rocks called kimberlites.
The formation of diamonds begins about 100 miles below the Earth’s surface in an environment of extreme heat (about 2,000 degrees Fahrenheit) and pressure (725,000 pounds per square inch). These conditions cause carbon atoms to bond in a unique way that forms a diamond’s crystal structure. This atomic arrangement is what makes diamonds incredibly hard and durable.
Over millions of years, volcanic activity pushes these diamonds to the Earth’s surface. They are transported in a rare type of magma called kimberlite, which forms kimberlite pipes. These geological formations are the primary sources of mined diamonds.
Mining
Once diamonds are near the surface, they must be extracted. There are several mining methods, including open-pit mining, underground mining, and alluvial mining. Each method has its own environmental impact and efficiency.
Open-Pit Mining
This method involves removing layers of sand and rock to reach diamond-bearing ore. It is commonly used for large, shallow deposits. Open-pit mining starts with the removal of topsoil and overburden to access the ore. Large machines and explosives are often used to break up the rock. The diamond-rich material is then transported to a processing plant where diamonds are extracted.
Underground Mining
When diamond deposits are located deep underground, tunnels are created to access the ore. This method is more complex and expensive. Miners create vertical shafts and horizontal tunnels to reach the diamond-bearing rock. The ore is then brought to the surface for processing. Underground mining is typically used when open-pit mining is not feasible due to depth and environmental concerns.
Alluvial Mining
This involves extracting diamonds from riverbeds and beaches where they have been deposited by natural erosion. Alluvial mining is often done by hand or with simple equipment. It can be more environmentally friendly than other methods but is labor-intensive and yields smaller amounts of diamonds.
Ethical Considerations
Ethical mining practices are crucial to ensure that diamonds are sourced responsibly. Many companies now adhere to the Kimberley Process, which aims to prevent “conflict diamonds” from entering the market. Conflict diamonds, also known as blood diamonds, are those mined in war zones and sold to finance armed conflict against governments.
The Kimberley Process Certification Scheme (KPCS) was established in 2003 to certify the origin of rough diamonds and ensure they are conflict-free. Participating countries must meet minimum requirements and implement national legislation to control diamond trade. While the Kimberley Process has reduced the flow of conflict diamonds, concerns about its effectiveness and loopholes remain.
Additionally, lab-grown diamonds are becoming a popular alternative, offering an ethical and environmentally friendly option. These diamonds are created in controlled environments using high-pressure, high-temperature (HPHT) or chemical vapor deposition (CVD) methods. They are chemically, physically, and optically identical to natural diamonds but do not involve the environmental and ethical issues associated with mining.

Sorting and Cutting: The Art of Shaping a Diamond
Sorting
Once diamonds are extracted, they are sorted based on their size, shape, color, and quality. This process involves both automated systems and human expertise. The rough diamonds are then categorized for industrial use or gemstone quality.
Sorting is a critical step that determines the future of the rough diamond. Industrial diamonds are used in various applications, such as cutting, grinding, and drilling, due to their hardness. Gem-quality diamonds, on the other hand, are destined to become jewelry.
Cutting and Polishing
Cutting a diamond is both an art and a science. The goal is to maximize the diamond’s brilliance and minimize wastage. This process involves several steps:
Planning
Experts use advanced software to plan the best way to cut each diamond. This involves analyzing the rough stone to determine the optimal shape and facets. The planning stage is crucial as it determines the final value of the diamond. Factors such as internal inclusions, external blemishes, and the rough diamond’s shape are considered to decide the best cut.
Cleaving/Sawing
The rough diamond is split into smaller pieces. Cleaving is done along the natural grain of the stone, while sawing is used for more complex cuts. Cleaving requires precise knowledge and skill, as one wrong move can ruin the diamond. Sawing, on the other hand, uses diamond-tipped blades to cut through the rough stone.
Bruting
This step shapes the diamond into a round stone, which is essential for the round brilliant cut. Bruting, also known as girdling, involves placing the diamond in a lathe and grinding it against another diamond to create a rough round shape.
Faceting
The diamond’s facets are cut and polished in two stages – first, the table and main facets are cut, and then the remaining facets are added. This is where the diamond’s brilliance is truly brought to life. Each facet must be precisely aligned to ensure maximum light reflection and sparkle.
Certification and Grading
After a diamond is cut and polished, it undergoes certification and grading to assess its quality. The most reputable labs for diamond certification include the Gemological Institute of America (GIA) and the Hoge Raad voor Diamant (HRD). These certifications provide information on the diamond’s carat weight, cut, color, and clarity, often referred to as the Four Cs.

Certification involves a detailed examination of the diamond by trained gemologists. They use specialized tools to assess the diamond’s attributes and provide a grading report. This report serves as a “diamond passport,” offering buyers confidence in the diamond’s quality and value.
