Man-Made Diamonds - One of the most talked topics in the jewelry world, for quite some time now. We are talking about a technology that allows to recreate the conditions in nature that result in carbon crystallizing into a diamond. Man-Made Diamonds are also the topic for this blog post.
A Man-Made Diamond (Or- Lab Created Diamond) is made by using advanced scientific knowledge and sophisticated technology, in order to recreate conditions similar to nature’s force exerted over a billion years approximately 100 miles underground. We are talking about a technology that allows to recreate the conditions in nature that result in carbon crystallizing into a diamond.
Because the process is very similar to natural growth, lab created diamonds have similar variations in color and clarity as mined diamonds. This means, just like in nature, no two lab created diamonds are alike. Each is unique and one of a kind.
Also, Lab created diamonds are cut and polished by some the finest diamond cutters in the world, just the same as mined diamonds.
Therefore, It is important to know that lab created diamonds are graded with the same standards as mined diamonds, and carry similar gemological certifications. When you purchase a lab created diamond, or a piece of jewelry set with a lab created diamond - You should recieve a gemological certificate with it.
So, How are lab diamonds created?
Diamonds can be grown in two ways.
The first is called High Pressure-High Temperature (HPHT) and the second is called Chemical Vapor Deposition (CVD).
Today we will focus on HPHT. Here is a brief explanation of the process-
HPHT diamond growth occurs within enormous pressure cookers called cubic presses, which can exert in excess of 70 metric tons.
Small diamond seeds are placed into the bottom of the growth cell. On top of the diamond seeds is placed a layer of additional carbon, in form of graphite.
The growth cell is then placed into the center of the cubic press and heated to 1,500 degrees C while being subjected to 1 million psi of pressure.
As a result, the graphite in the growth cell is melted into a liquid. Then it is very carefully cooled - into the form of a diamond crystal.
Lab Created Diamonds are, by definition, Conflict Free.
