The Distilled Diamonds lab

Our Process

The technology at DD is duplicated to recreate the exact conditions that are vital in growing a natural diamond, not under, but above the Earth’s surface. These grown diamonds are created using the Chemical Vapour Deposition (CVD) method.

CVD Reactor V3

How do we make a lab-grown diamond?

Lab-grown diamond seeds are loaded into a CVD reactor (CVD stands for Chemical vapor deposition). Then, a mix of gasses containing carbon is added at a very low pressure. Microwaves are added to heat the gases and generate a plasma. When the temperatures climb over several thousand degrees, the gas molecules break apart and carbon atoms bond to the seeds, growing them one layer at a time. Once the stones are big enough (about 2 weeks for one carat) they can then be cut and polished.

Product Technology

The Chemical Vapor Deposition (CVD) process replicates the crystallization of carbon over a diamond seed inside a vacuum chamber. These plates also called as seeds are placed inside the vacuum chamber of the system on a Metal disc.

Then the chamber is closed and vacuum is created inside the chamber using rotary pump so that all the gases are evacuated from the chamber. Then gas mixtures of argon, methane, nitrogen, hydrogen are introduced in the vacuum chamber & microwave is used to make the plasma in the system.

The Super-Hard Material is grown using gas mixtures in appropriate ratio at desired temperature and pressure in the chamber of this system using microwave power. After 100 to 500 hours, the system is switched off. They are polished using the same equipment and techniques for gem application. The only difference is origin. We produce Single Crystaline Super-Hard Material’s using CVD Technology.

Lab-grown diamonds are now becoming a popular alternative for many people, since they can have the same beauty and properties as a mined diamond and are often more affordable
