| Size | Can be grown up to several carats |
| Price | Generally lower than natural diamonds, but varies depending on size, color, and quality |
| Parameter | Description |
|---|---|
| Breeding method: | Two methods, HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition). |
| raw material: | Diamond seed (seed) and carbon source (for CVD method). |
| pressure: | Generally between 50-70 kbar (HPHT method) or 0.1-1 kbar (CVD method). |
| temperature: | Generally between 1200-1500°C (HPHT method) or 700-1100°C (CVD method). |
| time: | Usually ranging from a few hours to a few days. |
| Metal catalyst: | Some CVD methods need to use, such as Ni, Co, etc. |
| Diamond Yield: | That is, the proportion of raw materials converted into diamonds, generally ranging from 0.1% to 50%. |
| Diamond Quality: | The color, size, impurity content, hardness and other indicators of diamonds can be controlled and adjusted through different cultivation conditions. |
