Diamond Mining: From Earth's Depths to Jewelry
Diamonds, the epitome of beauty and luxury, have a fascinating journey from deep beneath the Earth's surface to becoming cherished pieces of jewelry.
The Formation of Diamonds
Diamonds are composed entirely of carbon, formed under intense pressure and heat more than 100 miles beneath the Earth's crust. Temperatures exceeding 750 degrees Fahrenheit and millions of years transform carbon into these precious stones. They remain hidden in diamond-bearing rocks until a volcanic eruption enables their rise to the surface.
Diamond Mining Techniques
Pipe Mining: Primary Source
In pipe mining, diamonds reach the Earth’s surface through volcanic pipes?"pathways connecting the Earth's mantle to its surface. Volcanic eruptions propel magma upward, potentially carrying diamond-bearing rocks like kimberlite or lamproite. These eruptions must be swift and forceful; otherwise, extended exposure to high temperatures could convert diamonds to graphite.
Initially, open-pit mining is conducted to inspect surface remnants for diamonds. Once these resources are depleted, large shafts are drilled near volcanic pipes to extract more diamond-bearing rock. This material is then processed at screening plants, where soil is separated from the diamonds.
Alluvial Mining: Secondary Source
Alluvial mining involves retrieving diamonds displaced by erosion, often found in ocean beds and riverbanks. Miners construct barriers to redirect water, using bulldozers or pumps to access the diamond-bearing rock. This rock is transported to screening plants for processing, separating rough diamonds from soil and silt.
Quality of Rough Diamonds
Only about 20% of mined diamonds are gem-quality, while the rest serve other purposes. Diamonds are categorized as follows:
- Gem Quality: Approximately 20% are suitable for jewelry, ranging from flawless to visibly included.
- Near Gem Quality: These require evaluation to determine their usability in jewelry or else they serve industrial purposes.
- Industrial Quality: Used in machinery like drills and saws, these have significant inclusions unsuitable for jewelry.
Interesting Facts about Diamond Mining
- Orapa Diamond Mine: The largest diamond mine is located in Botswana, Africa.
- Global Presence: Diamonds are mined in 25 countries across all continents except Antarctica, where mining is prohibited by international agreements.
- U.S. Consumption: Although the U.S. is the largest diamond buyer, it has only one mine in Arkansas.
- Extraction: Processing 200 tons of ore yields just one carat of gem-quality diamond.
- Gem Quality Ratio: Only 20% of mined diamonds qualify as gem-quality.
These insights reflect the intricate journey diamonds undergo to become coveted treasures, underscoring their rarity and value.
