Synthetic diamond. Labgrown diamond ( LGD; [1] also called laboratorygrown, laboratorycreated, manmade, artisancreated, artificial, synthetic, or cultured diamond) is diamond that is produced in a controlled technological process (in contrast to naturally formed diamond, which is created through geological processes and obtained by mining ).

Diamonds require temperatures of about 2200 degrees Fahrenheit, and pressure of about 725,000 pounds per square inch. It is this extreme heat and pressure, followed by cooling, which gives diamonds hardness not found in coal or any other substance. The cooling takes place when the diamonds are forced to the surface by the volcanic eruption.

The process of creating diamonds from coal is known as carbon conversion, and it works by exposing coal to extreme temperatures and pressures. By employing this method, jewelers are able to create diamonds of various sizes, shapes, and hues. Creating a diamond from coal requires a highpressure, hightemperature (HPHT) process to be used.

December 17, 2022 by July Though most people think of diamonds as being clear, they can actually come in a variety of colors. And, contrary to popular belief, diamonds are not rare. In fact, coal is made of the same element as diamonds: carbon. So, if diamonds are simply compressed carbon, can you compress coal into diamond?

Coal has no role in the formation of diamonds. Also, when diamonds are synthesized using the High Pressure, High Temperature () technique, scientists replicate the crushing force of the earth by applying a high amount of pressure and temperatures as high as 5000 degrees Fahrenheit to pure carbon pieces.

A pervasive myth about how natural diamonds are formed is that they come from buried coal, squeezed at high pressures. But the real story is far more exciting. Scientists are continuing to unravel details about how they form and what they can tell us about the inner workings of our planet. Diamonds are exotic because they originate from so deep ...

Diamonds are actually much older than plants, which are the main ingredient for the formation of coal. The basic oldfashioned recipe for a diamond calls for: Carbon deposits, deep within the earth, that are subjected to temperature and pressure. The exact time that it takes for a diamond to form within the earth is unknown.

The carbon neutral process at Aether is used to offset 20 tonnes of CO2 for each carat of diamonds manufactured. A twocarat diamond can be used to offset an individual's carbon footprint for the next two and a half years. Despite efforts by large diamond companies to tarnish the labgrown diamonds, the diamonds themselves are of good quality.

The most direct way to turn coal into diamond is through a process called chemical vapor deposition (CVD). In a CVD reactor, a mixture of gasses is passed over a substrate material, and the gasses deposit a thin film of carbon onto the substrate. If the conditions are right, the carbon film will crystallize into diamond.
