Strategic partners
We offer lab-grown diamonds
We offer lab-grown diamonds produced using both HPHT (High Pressure High Temperature) and CVD (Chemical Vapor Deposition) technologies, providing our partners with flexibility and choice.
The HPHT method is based on high pressure and high temperature conditions, replicating the natural environment in which diamonds are formed — a harmonious symbiosis of nature, science, and advanced human technology.
The CVD method, or Chemical Vapor Deposition, is a modern and highly controlled process that allows for precise growth of high-quality diamonds.
Both technologies are advanced, well-developed, and capable of delivering exceptional quality, brilliance, and consistency. The choice between HPHT and CVD ultimately depends on the specific preferences and requirements of our clients.
At Ukrainian Diamonds Company, we work closely with our partners to provide the most suitable solution tailored to their needs.
