Discover the fascinating process behind the creation of CVD lab-grown diamonds, a modern marvel in the world of gemstones. The process includes precise steps like seed selection, diamond formation, cutting, and polishing, followed by grading and certification. Understanding how CVD lab-grown diamonds are made reveals the blend of innovation and precision that ensures their quality and brilliance.
Diamond Seed Selection
At MYZA, the creation of CVD lab-grown diamonds starts with selecting a high-quality diamond seed. This seed, a thin slice of diamond, acts as the foundation for the new diamond. It is crucial to choose a seed that is free from impurities and defects, as this influences the quality of the final product. The diamond seed is typically sourced from a high-purity diamond to ensure the best results.
Chemical Vapor Deposition (CVD)
Once the diamond seed is selected, it undergoes the Chemical Vapor Deposition (CVD) process. In this process, the seed is placed in a chamber filled with carbon-rich gasses, such as methane. The chamber is then heated to extremely high temperatures, causing the gasses to ionize into plasma. This plasma breaks down the carbon molecules, allowing carbon atoms to settle onto the diamond seed, layer by layer, and form a new diamond.
Growth and Diamond Formation
During the growth phase, the carbon atoms continue to deposit onto the diamond seed, gradually forming a larger diamond. This process can take several weeks, depending on the desired size and quality of the diamond. The controlled environment ensures that the diamond grows uniformly, with minimal impurities and defects.
Cutting and Polishing
Once the diamond has reached the desired size, it is removed from the CVD chamber and undergoes cutting and polishing. Skilled craftsmen use advanced tools and techniques to cut the diamond into the desired shape and facets. The precision of the cutting process is essential to enhance the diamond's brilliance and overall appearance.
Grading and Certification
After cutting and polishing, the diamond is graded and certified by gemological experts. The International Gemological Institute (IGI), a renowned gemological laboratory, leads the way in grading and certifying both mined and lab-grown diamonds.

Final Inspection
The final inspection involves a thorough examination of the diamond to ensure it meets MYZA quality standards. Any imperfections or defects are identified and rejected at MYZA Labs. This step ensures that only the highest quality diamonds reach the MYZA esteemed clientele.
