CVD (Chemical Vapor Deposition) lab diamonds are created using a high-tech process that replicates the natural conditions under which diamonds form, just faster and more controlled.
Here’s a step-by-step overview of how they are made:

1. Diamond Seed

• The process starts with a thin slice of diamond called a diamond seed, often made of natural or lab-grown diamond.

• This seed acts as a foundation for the new diamond to grow.

2. Vacuum Chamber Setup

• The seed is placed in a CVD reactor chamber, which is then filled with carbon-rich gases (typically methane and hydrogen).

• The chamber is heated to around 800–1200°C.

3. Plasma Activation

• A microwave or plasma energy source is introduced to ionize the gas, breaking down methane into carbon atoms.

• These carbon atoms settle onto the diamond seed, layer by layer, forming a new diamond crystal.

4. Diamond Growth

• Over a few weeks, the diamond grows atom by atom. The environment is tightly controlled for purity and quality.

• The result is a rough diamond crystal ready for cutting and polishing.

5. Cutting & Polishing

• Just like mined diamonds, CVD diamonds are cut, faceted, and polished by skilled artisans to bring out their fire, brilliance, and clarity.

6 Certification

• Finished diamonds are graded and certified by reputed labs like the IGI or GIA, using the same standards as natural diamonds.

 Key Benefits of CVD Diamonds:

• Ethical & conflict-free

• Environmentally friendly

• Identical to mined diamonds in appearance and durability

• More affordable for the same quality
