A CVD diamond is not artificial - it is 100% genuine diamond, identical in every way to the diamonds found in nature. You might hear some people call CVD diamonds ‘artificial diamonds’, but this refers to the artificial environment in which they are created, rather than the diamonds themselves being fake.
Diamond seeds are placed at the bottom of the press. The internal part of the press is heated above 1,400 °C (2,550 °F) and melts the solvent metal. The molten metal dissolves the high purity carbon source, which is then transported to the small diamond seeds and precipitates, forming a large … Ver mais Lab-grown diamond (LGD; also called laboratory-grown, laboratory-created, man-made, artisan-created, artificial, synthetic, or cultured diamond) is diamond that is produced in a controlled technological … Ver mais Traditionally, the absence of crystal flaws is considered to be the most important quality of a diamond.
