How To Find Diamonds In Rivers

How Are Diamonds Mined?

Although your search for a natural diamond may begin with a trusted online retailer or in a velvet lined drinking glass case, diamonds come from—or are more than accurately mined from—a source much closer to globe. About i hundred miles hush-hush, heat and pressure from the earth crystallize carbon into rough diamonds. Merely how are diamonds mined so that they get from the earth to your ring?

A specific type of volcanic eruption, the kimberlite eruption, brings Kimberlite, a diamond-containing igneous stone, closer to the earth's surface—with the most recent eruption occurring over 100 million years agone. Kimberlite is normally found in kimberlite pipes—vertical structures in the earth's chaff. Diamonds are mined from Kimberlite through iii types of diamond mining: alluvial mining, pipage mining, and marine mining.

How are diamonds mined? Run across the 3 different methods

Alluvial diamond mining occurs in riverbeds and beaches, where thousands of years of erosion and natural forces such as wind, rain, and water currents wash diamonds from their chief deposits in kimberlite pipes to beaches and riverbeds. Miners build walls or divert rivers to expose the diamond-bearing dry river or ocean bed. While workers initially sifted through the sand at the original site, the process soon advanced, with sand beingness transported to a screening facility to exist more than efficiently processed.

Every bit the global demand for diamonds increased, diamond miners adult modern day's near common class of diamond mining: pipe mining. While alluvial mining requires waiting for diamonds to first ascension up through kimberlite pipes and be washed away past erosion to settle on river or ocean beds, pipe mining allows diamond miners to strike closer to the source—the kimberlite pipes. Piping mining has ii forms: open up-pit diamond mining and hush-hush diamond mining.

Open-pit diamond mining is used closer to the earth's surface, every bit miners remove the layers of sand and stone just higher up the kimberlite rocks. In contrast, underground mining requires the creation of two parallel and vertically continued tunnels where miners in the height tunnel smash the ore of the kimberlite pipes which falls and collects on the lesser tunnel.

Marine diamond mining

The 3rd method, marine diamond mining, extracts diamonds from the sea floor. While the primeval form of marine diamond mining laboriously required a swimmer to collect gravel from a shallow seabed, modern technology granted admission to greater depths through horizontal and vertical marine mining. Horizontal marine diamond mining uses a crawler to suck gravel from the ocean floor to the surface via flexible pipes, while vertical diamond mining uses a large, ship-mounted drill to pull up the diamond-begetting gravel.

Diamond mine locations

These mining techniques occur in diamond mines all over the world. Diamond mines exist as both privately owned entities and government sponsored enterprises, with some the primeval diamonds found in India in the 4th century BC. Following the decline in Indian diamond mining, diamonds was discovered in Brazil in the 1720s, N America in the 1840s, and in Africa in the 1860s. The rise of African diamond mines sparked the Great Diamond Blitz every bit well as the Kimberly Mine, the first largescale diamond mining operation.

The largest diamond mines

While Africa was once the center of diamond mining, producing up of 90 per centum of the global diamond supply, Africa now produces less than 50 pct of the globe's diamonds. Data from the 2016 U.S. Geological Survey states that Russia produces the well-nigh gem-quality diamonds—housing half of the world's largest diamond mines— followed by Botswana, Canada, Angola, and Due south Africa. But the coveted title of "world'due south largest diamond mine" can vary.

In 2016, global diamond adept, Ehud Arye Laniado, listed the world's largest diamond mines (determined by reserve size) as the Orapa diamond mine and Jwaneng diamond mine in Botswana, and the Jubilee diamond mine of Russian federation. In contrast, diamond expert Paul Zimnisky gave his ranking of the earth'southward largest diamond mines equally the Jwaneng diamond mine, the Jubilee diamond mine, and Russia'southward International diamond mine. Even so, large and commercially viable diamond mines are rare, with only nearly xx major diamond mines in existence today.

The Kimberly Process and conflict diamonds

The rarity of large diamond mines, combined with the high value and extreme labor required to mine diamonds means that the diamond mining industry requires extra precautions for safe and ethical diamond mining practices. In order to standardize mining practices and gainsay the sale of disharmonize diamonds— diamonds used to fuel civil unrest or wars—the international customs established the Kimberley Process in 2000, a no tolerance policy against the use of conflict diamonds. The Kimberley Process, adopted by 74 governments, requires the issuance and authorization of a document for each mined rough diamond in order to promote safety and ethical diamond mining practices.

With all this, it is undeniable that diamonds undergo a long journey—from the warm belly of the Globe to hard-working diamond miners, jewelers, and retailers—in order to find their way dwelling to you and your loved ane.
