There are two primary methods for growing diamonds:
- HPHT (High Pressure High Temperature): an older method that mimics deep-Earth conditions. It can produce gem-quality stones but often leaves metallic inclusions and has less control over color.
- CVD (Chemical Vapor Deposition): a more advanced process where diamonds grow layer by layer in a plasma chamber. CVD produces larger stones with greater purity, fewer inclusions, and more consistent quality.
At Bow Tie Lab Diamonds, we use only CVD diamonds. This ensures the highest clarity, better color control, and a level of precision that matches our commitment to excellence. By focusing on CVD, we deliver diamonds that meet the strictest grading standards, certified by IGI or GIA.
