Synthetic diamond is produced in a process; as opposed to natural diamond, which is created in geological processes. Synthetic diamond is also widely known as HPHT diamond or CVD diamond, denoting the production method, High-Pressure High-Temperature synthesis, respectively.
A natural diamond is formed over millions of years under the Earth's crust, while a synthetic diamond is created in a laboratory environment. Bestingems offers a range of natural and synthetic diamonds, each with unique qualities to suit different preferences and budgets.
Man-made diamonds are often referred to as synthetic diamonds or lab-created diamonds.
Diamond Nexus offers both synthetic diamonds(made with pure carbon) as well as diamond simulants that are not made with pure carbon, but are nearly identical to a natural diamond besides having different elements. The pure carbon gems are only available in a canary color though.
A synthetic diamond is a mineral made of carbon, and possesses all the same properties as a mined diamond. It has a cubic crystalline structure, a refractive index of 2.42, dispersion of 0.044, mohs hardness of 10 and a density of 3.52.
Dr. H Tracy Hall (October 20, 1919 - July 25, 2008) Dr. Hall was an American physical chemist, and the first person to produce synthetic industrial diamond in 1954, according to a reproducible, verifiable and witnessed process, using a press of his own design. The question "who invented synthetic diamond?" doesn't relate to gem quality diamonds that are created in the lab . The first diamonds made by man were used for industrial purposes such as oil & gas drilling, grinding & tools.
A real diamond is generally more valuable than a synthetic diamond due to its rarity and natural creation process. Real diamonds are formed deep within the Earth's mantle over millions of years, while synthetic diamonds are created in a controlled laboratory setting. These differences in origin and scarcity contribute to the higher value of natural diamonds.
Element Six was created in 1960 as the industrial arm of De Beers, with a focus on synthetic diamond production.
Synthetic diamond is not considered a mineral because it is not naturally occurring. Minerals are formed through natural geological processes, whereas synthetic diamonds are created by humans in a laboratory setting. Additionally, minerals have a defined chemical composition and crystal structure, while synthetic diamonds can have different impurities and defects due to their artificial production process.
Carbon
Creating a synthetic diamond can take anywhere from several days to a few weeks, depending on the method used and the size of the diamond being produced.
