HPHT vs CVD: Understanding the Difference in Lab-Grown Diamonds
In recent years, lab-grown diamonds have become increasingly popular, offering an ethical and eco-friendly alternative to mined diamonds. There are two primary methods of creating these diamonds: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). While both processes create real diamonds, the way they are made differs significantly. This article explores the differences between HPHT and CVD, providing insight into their processes, benefits, and key characteristics.
What is HPHT?
HPHT, or High Pressure High Temperature, is one of the earliest methods used to produce lab diamonds. The process mimics the natural conditions under which diamonds form deep within the Earth. It involves placing a carbon source, such as graphite, in a high-pressure, high-temperature chamb...
