Finding the Unpolished Diamonds Within the World of Local Contractor in Lov
A gemologist can sift through tons of rock to produce one carat of rough diamond. The process is necessarily destructive, and the largest roughs are often pulverized.
Mansori held the Sewelo in his bony hands and studied it. It was a big stone, and it might sell at tender for two or twenty-five million dollars.
Kimberlite
The diamonds in kimberlite pipes are formed hundreds of kilometers below the surface. Powerful magma eruptions bring them to the surface in pipes. The eruptions rise at speeds faster than the speed of sound. They can also eject pyroclastic material, like ash and rock fragments. The combination of volatile-rich magma chemistry and rapid ascent keeps the diamonds stable so they don’t convert to graphite.
The lava-like magma in a kimberlite pipe is a mix of olivine and pyroxene. It’s rich in magnesium and iron. It also contains compatible trace elements, such as nickel, chromium, cobalt, and copper.
These elements indicate the magma came from the mantle. But they aren’t enough to identify the exact composition of the original magma.
Geochemistry
Diamonds are a rare commodity. An ounce of rhodium, which has many uses in metallurgy and is an important component in catalytic converters, costs about ten thousand dollars. But a clear, internally flawless rough diamond of the same size can cost a jeweller six million dollars.
Usually, a mining firm tenders its rough diamonds for sale at auction, and then walks away with a check. But Lucara has taken a different approach with the Sewelo.
He held the stone in his bony hands and rotated it this way and that, examining its facets and how they blended with its black rind. A diamond cutter needs to know how a stone will respond to the cutting process.
Geology
Diamonds have a reputation for being tough, but if you try to crush one, it will break apart along fissure lines. A diamond can be distinguished from quartz by its cubic (isometric) form: if you hold it to the light and look through it, you should see flat surfaces; quartz will have curved conchoidal ones.
The discovery of the Lesedi La Rona and other diamond mines in copyright loosened De Beers’ stranglehold on the industry, but it still remains a very competitive business. Madderson calls the new players “fucking good.”
Mansori held the Sewelo in his bony hands and turned it this way and that. He had spent a lot of time staring at the stone.
Geophysics
Geophysicists use tools like acoustic surveys, magnetotellurics and airborne radar to locate valuable resources. Among these are precious and industrial metals, and coal, oil and natural gas.
Mansori knew that he stocks and bonds Loveland had a chance to make some serious money from the Sewelo. But it was not clear how much he would be able to sell it for. He must consider the geometry of its facets--the way that they cut across various planes--to maximize the diamond’s value.
Traditionally, manufacturers of rough diamonds have analyzed a stone and then sought out wealthy clients for it. But Lucara and HB are trying something new: they’re selling the diamonds directly to retailers.
Diamonds
Diamonds are made from carbon, which is one of the most abundant elements on earth. But it’s the way that carbon atoms are bonded together that makes them so special.
Unlike graphite (the soft lead tip on the end of your pencil) every carbon atom in a diamond is connected to four other carbon atoms in an incredibly tight pattern. This gives diamond its strength and allows it to sparkle brilliantly in light.
The diamonds that make it to market are sorted according to the “4 C’s”; cut, clarity, color and carat. Once a stone is polished it’s ready to be sold as jewelry or for industrial uses like cutting and drilling.
