Natural Diamonds. The word itself conjures images of dazzling brilliance, timeless elegance, and enduring love. But have you ever stopped to think about where these captivating gems truly come from and the incredible journey they undertake to adorn our jewellery?
In this blog post, we’ll delve deep into the world of Natural Diamonds, exploring their formation, mining, market, and everything in between. Prepare to be amazed by the ancient story etched within each sparkling stone.

What are Natural Diamonds, Anyway?
Simply put, natural diamonds are diamonds formed by natural geological processes. This is crucial to distinguish them from lab-grown diamonds, which, while chemically identical, are created in a factory setting. Natural diamonds are gifts from the Earth, born deep within our planet billions of years ago.
The Earth’s Fiery Crucible: How Natural Diamonds are Made
Imagine a place hundreds of kilometers beneath your feet, in the Earth’s mantle. Here, immense pressure (around 725,000 pounds per square inch) and scorching temperatures (over 2,200 degrees Fahrenheit) reign supreme. It’s in this extreme environment that carbon atoms, over billions of years, crystallize into the incredibly strong and beautiful structure we know as diamond.
This process typically occurs in ancient parts of the Earth’s crust, often beneath continental plates. These diamond-bearing rocks are then brought closer to the surface through volcanic eruptions, specifically through conduits called kimberlite and lamproite pipes. Think of these pipes as elevators carrying these precious gems from the depths to a reachable level.
Unearthing Brilliance: How Natural Diamonds are Mined
Mining natural diamonds is a complex and often challenging undertaking. There are several primary methods used:
- Open-Pit Mining: This is often used when diamond-bearing ore is close to the surface. Vast pits are excavated, and large quantities of rock and earth are removed to access the diamond-rich kimberlite or lamproite pipes.
- Underground Mining: When diamond deposits are deeper underground, underground mining becomes necessary. Complex tunnel systems are built to reach the ore, which is then extracted and brought to the surface. This method is more expensive and technically demanding.
- Alluvial Mining: Diamonds are incredibly durable and can be eroded and transported by rivers and streams over millennia. Alluvial mining involves searching for diamonds in riverbeds, coastlines, and even seabeds where they have been deposited. This can be simpler but often yields smaller, less concentrated deposits.
- Marine Mining: Off the coasts of some countries, diamonds have been eroded and deposited on the seabed. Specialized ships and underwater equipment are used to extract diamond-rich gravel from the ocean floor.
The Human Touch: How Many People Mine Diamonds?
Mining diamonds is a labor-intensive industry that employs hundreds of thousands of people worldwide. From geologists and engineers to heavy machinery operators, miners, and sorters, a vast workforce is essential at every stage. The number of people directly involved in mining at any given mine varies greatly depending on the size and type of operation. Large-scale mines can employ thousands, while smaller artisanal operations might involve just a few individuals or families.

From Mine to Market: The Cost of Bringing Diamonds to You
The journey of a natural diamond from deep within the Earth to the jewellery store is a long and costly one. The “cost to mine to market” is a multifaceted figure that includes:
- Exploration Costs: Finding diamond deposits is expensive and often unsuccessful. Geological surveys, drilling, and analysis are all significant investments.
- Mining Equipment and Infrastructure: Setting up and maintaining mines requires massive investments in heavy machinery, processing plants, infrastructure (roads, power), and safety equipment.
- Labor Costs: As mentioned, the industry is labor-intensive, and wages for the workforce contribute significantly to the overall cost.
- Processing and Sorting: Once mined, the rough diamonds need to be crushed, processed to separate the diamonds from the ore, and then meticulously sorted by size, color, clarity, and carat weight.
- Cutting and Polishing: Rough diamonds are far from the sparkling gems we see in jewelry. Skilled artisans, known as diamond cutters and polishers, are crucial to transforming these rough stones into the brilliant forms that maximize their beauty and value. This is a highly skilled and often time-consuming process.
- Transportation and Security: Diamonds are high-value goods, and their transportation requires robust security measures, adding to the overall cost.
- Marketing and Distribution: From diamond dealers to jewelry manufacturers and retailers, there are numerous steps and players in the supply chain, each adding their margin and marketing costs.
The Diamond Market: How Natural Diamonds are Sold
Natural diamonds are traded through a complex global network. The journey from mine to consumer typically involves:
- Mining Companies: Sell rough diamonds to diamond trading companies or dealers.
- Diamond Dealers and Trading Centers: These centers (like Antwerp, Belgium; Mumbai, India; and Tel Aviv, Israel) are hubs for sorting, valuing, and trading rough and polished diamonds.
- Diamond Manufacturers/Cutters and Polishers: Purchase rough diamonds and transform them into polished stones.
- Jewelry Manufacturers: Buy polished diamonds and set them into jewelry designs.
- Retailers and Jewelry Stores: Sell diamond jewelry to consumers.
Who are the Customers of Natural Diamonds?
The customer base for natural diamonds is incredibly diverse and spans the globe:
- Individuals: The most significant customer segment. People purchase diamond jewelry for various reasons: engagement rings, wedding bands, anniversary gifts, celebratory presents, personal adornment, and as investments.
- Businesses: Diamond components are used in various industries beyond jewelry, including industrial applications (cutting tools, abrasives), technology (heat sinks, semiconductors), and research.
- Collectors and Investors: Rare and exceptional natural diamonds, especially colored diamonds, are often sought after by collectors and investors as valuable assets.
The Sparkle in Your Jewellery: The Cost After Setting
The final price of a diamond in jewelry is influenced by many factors beyond just the cost of mining and the diamond itself. “What does it cost after studding in jewelry?” depends on:
- The Diamond (The 4Cs): Carat, Cut, Clarity, and Color are the primary determinants of a diamond’s value. Larger, higher quality diamonds naturally command higher prices.
- The Metal Setting: The type of metal used (gold, platinum, silver) and the weight of the metal contribute to the cost. Platinum is generally more expensive than gold, and gold more than silver.
- Jewelry Design and Craftsmanship: Intricate designs, the complexity of the setting, and the skill of the jeweler all impact the price.
- Brand and Retailer Markups: Luxury brands and established retailers often have higher markups compared to smaller independent jewelers.
- Geographic Location and Market Demand: Diamond prices can vary slightly based on location and local market conditions.
Natural Diamonds: More Than Just a Gem
Natural diamonds are more than just beautiful stones. They represent billions of years of geological history, an intricate and often arduous journey from the Earth’s depths, and the skilled hands that bring their brilliance to light. When you wear a natural diamond, you’re not just wearing a gem; you’re wearing a piece of the Earth’s story, a symbol of enduring beauty, and a testament to nature’s incredible power.
