The Ethical Implications of Choosing Lab-Grown Diamonds over Natural Diamonds


Mining permanently scars the environment, and the price of natural diamonds remains high as they take thousands of years to form on the earth. So, it stands to reason that lab-grown diamonds are a much better option, and are often of a superior quality to the mined diamond. While making the decision on which diamond to purchase, it is important to be fully informed, when looking at a Lab Grown Diamonds: Complete Buying Guide of Lab Diamonds | Rare Carat has many of the answers to the ethical and practical questions asked by clients.

How are Lab Grown Diamonds Made?

There are two main methods used to create diamonds, and over 100 years ago it was discovered that diamonds were almost pure carbon. the methods used are HPHT, (high-pressure high temperature) and CVD (chemical vapor deposition).


This method is the closest to the natural process, as it crystallizes the carbon at high temperatures under high pressure. like it would on the earth. The crystal grows gradually using this method.


The CVD method was discovered about 50 years ago and is becoming the preferred way to create diamonds, as the machines are smaller and the growing time is shorter. the process starts with a crystal seed grown by the HPHT method and inserted into a CVD chamber. A mixture of gases primarily hydrogen and methane are injected into the chamber and heated by a microwave beam. The molecules split and remain in the chamber where they are grown under temperature-controlled conditions. Molecules rain down onto the seed and the diamonds grow in layers.

When the diamond is finished it looks rough and dirty because it is covered in excess carbon, this is removed with a laser, and treated, allowing the lovely diamond to emerge. Because it is exactly the same chemical composition as a natural stone, it will be graded on the same scale as a natural diamond and the 4 CS still apply.

  • Carat-weight
  • Color
  • Clarity
  • Cut

Both GIA and IGI grade lab-grown diamonds, and although growing a diamond in the lab does cost money, it is cheaper than mining a stone. So, buying your lab-grown diamond is not only cheaper but much better for the environment.
