What Are Lab-Grown Diamonds?Natural vs. Lab: What's the Difference?
A Brief History of Lab Grown Diamonds
Lab created diamonds, also known as lab-formed diamonds, cultured diamonds, synthetic diamonds and, man-made diamonds, have been around since the 1950s. However, it wasn't until recent advanced technology that lab diamonds became a viable option for jewelry. In the past, lab grown diamonds were primarily used for industrial purposes, such as cutting tools and abrasives. But now they are produced with the same physical, chemical, and optical properties as their natural counterparts using highly specialized equipment, for use in jewelry,
The Process of Creating Lab Grown Diamonds
The process of creating lab diamonds involves replicating the natural conditions that cause diamonds to form in the earth's mantle. This is done in a controlled environment using cutting-edge technology and equipment. The two main methods for creating lab grown diamonds are High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD).
In the HPHT method, a small diamond seed is placed in a chamber with carbon and subjected to immense pressure and extreme heat. This causes the carbon to crystallize and form a diamond around the seed. In the CVD method, a diamond seed is placed in a chamber with a carbon-rich gas. The gas is then heated and ionized, causing the carbon atoms to bond and form a diamond on the seed. CVD is the method used to create larger loose diamonds.
Both methods result in a diamond that is chemically and physically identical to a natural diamond. The only difference is the origin. Both methods create the ideal stones for a wide range of diamond jewelry, from engagement and wedding rings to stud earrings and pendant necklaces.
