The unique properties of diamond are well known a long time ago and therefore are extensively used. However, the most general aspects of diamond origin are not yet clearly determined. Hydrothermal synthesis as any heterogeneous reactions occurring under the conditions of high-temperature-high-pressure (> 100 °C, > 1 atm) in aqueous solutions in closed system has a growing interest among the scientists in particular due to a possibility of synthesis of new phases or crystals growth. During this study the diamond particles or films were produced through hydrothermal interaction of 1,1,1-Trichloroethane and 10 M NaOH in the presence of diamond or cubic BN seeds at temperature 300 °C and pressure 1 GPa. Synthesized diamond was thoroughly characterized by TG-DTA, SEM (EDX) and had (220) preferable orientation according to XRD pattern. These results demonstrate that the hydrothermal growth of diamond in like manner with quarts and emerald is possible.
