Our CVD Technology
At Carbon Cube Jewels, we use advanced Chemical Vapor Deposition (CVD) to cultivate premium-quality diamonds:
- Seed Selection: Starts with ultrapure diamond seeds.
- Carbon Deposition: A carbon-rich gas is ionized and deposited layer by layer onto the seed.
- Controlled Environment: Temperature, pressure, and gas composition are precisely regulated for optimum crystal growth.
- Polishing & Grading: Finished diamonds are cut, polished, and graded by expert gemologists for color, clarity, and cut.
This meticulous process ensures consistent quality and exceptional brilliance.
