Lab-Grown Diamonds
vs. Natural Diamonds

Lab grown diamonds are (you guessed it) grown in a lab. It starts with a tiny carbon diamond seed, which are from pre-existing diamonds. There are two primary techniques used to create lab diamonds: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).

• HPHT Lab Grown Diamonds: This method mimics the natural conditions under which diamonds form inside the Earth. A diamond seed is placed in a chamber, subjected to intense heat (over 2,000 degrees Celsius) and pressure (1.5 million pounds per square inch). The carbon atoms in the chamber bond with the seed; therefore, crystallizing into a diamond.
• CVD Lab Grown Diamonds: This method starts with a thin piece of diamond seed being placed in a vacuum chamber filled with a carbon-rich gas mixture (typically methane and hydrogen), which is heated to break down the gas molecules. Carbon atoms settle onto the seed, building layer by layer until the diamond reaches its desired size. Some CVD diamonds may undergo additional pressure and heat treatment after growth.

Both methods simulate part of the natural diamond-forming process, resulting in high-quality diamonds that are identical to mined diamonds in every way. After several days, a rough diamond is created, then cut, polished and set in jewelry. Both methods yield real diamonds with no differences in durability, differing only in growth patterns and production time.
