However, their beauty isn’t the only benefit to choosing lab grown. But isn’t that the beauty in diamonds? Each one is unique and special.Īre there benefits to choosing lab grown diamonds?Ĭertainly! Lab grown diamonds are just as beautiful as diamonds found within the earth. While there is more control in the lab, we can’t totally outrun mother nature. Just like in nature, lab grown diamonds can have a wide range of colors and clarities. Lab grown diamonds also share the same crystal structure, refractive qualities and hardness. They have the same chemical properties as a natural diamond. Even to the trained eye, it is impossible to tell the difference between a diamond grown in a lab and a natural, mined diamond. Once that occurs, pure carbon begins to stick to the seed and a new diamond forms.ĭiamonds grown in a lab are really diamonds. This technology essentially breaks down the molecular bond of the gas. The gases are then ionized into plasma using technology similar to microwaves. The chamber is filled with carbon-rich gases (such as methane and hydrogen). Similarly, CVD uses a small diamond seed, which is placed inside a sealed chamber and heated to over 1,400 Fahrenheit. The newly formed diamond is then carefully cooled, resulting in a product that can be cut down into mountable diamonds. The combined pressure and heat start melting the carbon, forming a diamond around the initial diamond seed. The carbon is also exposed to temperatures over 2,700 Fahrenheit. Then using either a belt press, a split-sphere press, or cubic press, the carbon is highly pressurized. Using the HPHT method, the small diamond seed is placed into a piece of carbon. Labs use two different methods to grow diamonds - High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). This means that carbon is subjected to high temperatures and high pressure in a controlled environment. They are created under conditions similar to how they would grow naturally. The easiest answer is that they are really diamonds, just grown in a lab. The project began in the 1940s, however, World War II postponed their work and it wasn’t until 1954 that the team had a successful result.įast forward to today, lab grown diamonds are gaining more and more popularity, not just in bridal jewelry but in all areas of fine jewelry. The project was codenamed “Project Super Pressure”. Lab grown diamonds were officially introduced when the first proven synthetic diamonds were made by General Electric. Several claims have been made about lab diamond manufacturing in the late 1800s and early 1900s, however none of them have ever been confirmed. Since then, many attempts have been made to produce diamonds in a laboratory, at a lower cost than mining for earth diamonds. Throughout history diamonds have been regarded as a symbol of love and commitment and have traditionally been the stone of choice for engagement rings and wedding jewelry.Īround 1797, it was discovered that diamonds were 'created' from pure carbon. Just like any good love story, we should start at the very beginning. You’ve been seeing the term pop up more and more in recent years, but what are lab grown diamonds - and what sets them apart?
