To the naked eye, lab-grown and natural diamonds sparkle the same. Both are graded on the 4Cs - cut, clarity, colour, and carat, and match in colour, quality and hardness.
In a lab, carbon is transformed into flawless diamond crystals using high pressure, high temperature (HPHT) and chemical vapor deposition (CVD) - just like in nature, but faster.
They use far less energy and resources than natural diamonds, making them a responsible choice. You can also enjoy the same breathtaking sparkle for less, without compromising quality.
