2. Cultivated diamond event development table:

1) 1950s: Lab-grown diamonds are introduced. Lab-grown diamonds at this time were produced using the high-pressure, high-temperature (HPHT) method and were mainly used for industrial purposes, such as in telecommunications and laser optics, and as abrasive materials, among others.

2) 1970s: General Electric researchers create the first gem-quality lab-grown diamond. They are clear enough and large enough to be used as stones in jewelry.

3) Mid-1980s: Manufacturers begin producing gem-quality grown-up diamond crystals on a commercial scale. At first, these lab-grown diamonds were almost all small and yellow or brown in color, but their quality improved over the ensuing decades.

4) 2000s: Diamonds were manufactured using the chemical vapor deposition (CVD) method, which required lower pressures and temperatures compared to the HPHT method.

5) Mid-2010s: The jewelry market can supply colorless lab-grown diamonds on a commercial scale. HPHT and CVD remain the primary production methods for lab-grown diamonds.
