Synthetic diamond - Wikipedia
Nanocrystalline diamond produced through CVD diamond growth can have a hardness ranging from 30% to 75% of that of single crystal diamond, and the hardness can be controlled for specific applications. Some synthetic single-crystal diamonds and HPHT nanocrystalline diamonds (see hyperdiamond) are harder than any known natural diamond.

1952 by William Eversole of the Union Carbide Corporation, but it took another two decades before GIA issued the first grading report for a laboratorymade diamond (Crowningshield, 1971). Virtually all single-crystal synthetic diamonds are made by two very different processes. High-pressure, high-temperature (HPHT) synthesis mimics some of the key conditions for natural diamond formation, with

Observations on CVD-Grown Synthetic Diamonds: A Review
Single-crystal, gem-quality CVD synthetic diamond was once considered a “holy grail” within the research community. A half-century of investigation between CVD’s early beginnings in 1952 until it advanced sufficiently that it became a research focus at GIA in 2003 (Wang et al., 2003) made that once-ambitious goal a reality.

synthetic diamond | Definition, Techniques, & Facts
Synthetic diamond, man-made diamond that is usually produced by subjecting graphite to very high temperatures and pressures. Synthetic diamond resembles natural diamond in most fundamental properties, retaining the extreme hardness, broad transparency (when pure), high thermal conductivity, and high electrical resistivity for which diamond is highly prized.
