Lab grown diamonds are gaining popularity for many reasons. The lab created diamonds are as beautiful as the natural diamonds and they hold the same characteristics as natural diamonds. Reducing the time of producing diamonds sounds amazing, and it can be done in a highly controlled environment by the experts. LGD Trade, have expertise in selling the best synthetic diamonds. A CVD diamond is made by following the most meticulous process.
Here is the process followed by the traders listed on LGD Trade.com to produce the best man made diamonds:
The man made diamond experts handpick the best diamond seeds. The process of picking up the diamond seed needs proficiency in identifying the seeds that can become a fine diamond later. Our experts perform this task with a highly meticulous approach. The selected diamond seeds are then placed on a specifically designed metal disk in a bunch of 15-30 pieces.
The growth chamber, also known as a diamond growing reactor is a highly controlled environment in which the natural conditions of producing diamonds are mimicked. Superheated gases are used that are produced with Chemical Vapor Deposition (CVD) to grow CVD diamonds. A High Pressure High Temperature (HPHT) technique is used to breed HPHT diamonds.
The heat of the diamond growth chamber range between 900 – 1200 Celsius. The diamond seed grows week by week under the controlled environment of different gases, temperature and pressure. As time passes, the diamond grows layer by layer and atom by atom like a natural diamond grows under earth’s crust.
Our technical experts keep monitoring the growth of the diamond seeds. At the moment when they sense the diamond holds the maximum characteristics of a gem and ready for the next step, they remove them from the growth chamber. At this stage, the lab created diamonds are raw diamonds in a cubic shape.
In a high-tech factory, the rough diamond is polished and also shaped in different shapes such as, round, princess, radiant, cushion, oval, pear, heart, marquise, and more. The final polished and shaped diamond holds the same look and feel as well as the atomic characteristic as a natural diamond.
These five step process takes a lot of experience to deliver you the best man made diamonds.
Each seed is made of a repeating lattice of carbon atoms - just like natural diamonds. It’s carefully evaluated to ensure they are free of inclusions.
Prepare the surface for growth and place diamond seeds on metal disk usually containing 15-30 diamond seeds.
Inject carbon-rich gases in chamber and excite the gases to an energy level where they form plasma.
Control chamber pressure and temperature in range of 900-1200 Celcius.
The activated carbon-hydrogen species attaches itself to the seed atom.
This process repeats itself endlessly for 3-4 weeks to replicate the crystal structure of the diamond seed in three dimensions.
Moment where seed crystal reach the desired diamond characteristics, quick removal alert been set to technician.
Rough diamonds are removed from the chamber to cut and polish into gems.
