2021-11-1 · (100)-Oriented commercial HPHT diamond crystals with size of 3 mm × 3 mm × 1 mm were used as substrate seeds for CVD diamond growth. The seed surface has been polished by standard CMP process, where the root-mean-square (RMS) of polished diamond seed can be estimated to be about 1.8 nm as shown in Fig. 1b.The Raman peak of the HPHT seed samples were ~1334.8 cm −1, indicating .
2021-11-9 · HPHT vs CVD diamonds. Ultimately, the key difference between an HPHT diamond and a CVD diamond is that they have different diamond growth patterns. If inspected closely with magnification, a lab diamond expert would potentially be able to tell the difference between an HPHT and a CVD diamond by looking at the crystal structure.

2021-11-22 · CVD and HPHT differ in terms of the creation process of the diamonds. HPHT has been around longer as a synthetic technique, whereas CVD is a newer, less expensive technique. While a CVD diamond is more likely to have brown streaks, the HPHT diamonds usually have a bluish streak.
