Natural Diamonds vs. Lab-Created Diamonds

In the great debate between natural diamonds and lab-created diamonds, there is no clear winner. Ultimately, you can choose whatever speaks to your heart. While natural diamonds boast a rare appeal, lab-created diamonds are an affordable alternative for budget-conscious consumers.

How Are Lab Grown Diamonds Made?

Lab-grown diamonds are made using a variety of high-tech methods that mimic the natural diamond creation process deep within the earth. A diamond seed is subjected to high pressures and temperatures in a controlled environment to create a diamond.

Here are the two main processes used:

  • HPHT: A small diamond seed is placed into a piece of carbon and is pressurized to about 1.5 million pounds per square inch and over 2,700º F. The carbon melts and forms a diamond around the diamond seed. The resulting diamond is then cooled down.
  • CVD: Similar to HPHT, CVD uses a small diamond seed and puts it inside a sealed chamber that is heated to over 1,400º F. The chamber is filled with methane and hydrogen. The gasses are then broken down allowing the carbon to stick to the seed and form a new diamond.
