Lab grown diamonds are optically and chemically identical to natural diamonds. The only difference is their origin. A diamond seed is placed in conditions identical to those in underground mines. Then, a carbon coating is added to help the diamond crystallize as it grows.

The crystalline form of carbon we call “diamond” can be attained only through intense heat, constant pressure, and a good amount of time. Nowadays, we can achieve that in a lab in specialized machines that knock a few billion years off the cooking time. The result is a lab grown diamond that differs from a mined diamond in name only.

If you were to look at both types of diamonds through a professional jeweler’s loupe, or if you were to inspect both diamonds on a molecular level, you would see no difference. The same result was achieved through very different processes.

Lab grown diamonds are manufactured using conditions that mimic the natural process that natural diamonds are subject to. Carbon is exposed to high temperatures and high pressure in a controlled environment (laboratory) thus creating a diamond.

Lab grown diamonds can be made using two different methods. The first is known as the HPHT method, where a small diamond seed is placed into a piece of carbon. The carbon is pressurized and exposed to high temperatures. Finally, the pressure and heat then melt the carbon allowing a diamond to form around the initial seed.

The second is the CVD method, which also requires a diamond seed. The seed is placed into a sealed chamber that is heated and filled with carbon-rich gasses. These gasses are ionized into plasma using advanced technology that breaks down the gasses’ molecules and allows pure carbon to stick to the seed, forming a new diamond.

Fun fact: It typically takes a lab grown diamond less than a month to grow. A 1-carat white diamond takes around two weeks to form, whereas fancy color diamonds like yellow and blue diamonds take between 5-10 days to form.

Lab grown diamonds are 100% real diamonds.

If you want to get technical, here’s what you need to know. Lab grown diamonds have the exact same optical, physical, and chemical properties as their mined counterparts. The only significant difference is their origin. One comes from a natural and uncontrolled environment, while the other is physically created in a controlled laboratory.

Even by definition, the two are indistinguishable. The Federal Trade Commission (FTC) defines a diamond as pure crystallized carbon in the isometric cubic system. This means that crystallized carbon is a gemstone known as a diamond regardless of whether a diamond was mined from the earth or grown in a lab.

• Greater brightness & higher purity
• Easily traceable origins
• Socially responsible (Ethically sourced)
• Greater affordability at 30% less than mined diamonds
• You can have a unique fancy color diamond made

Fun fact: Lab grown diamonds are grown through a sustainable process. The CVD manufacturing method uses chemical vapor deposition (CVD), which makes it easier to keep up with demand without sacrificing the diamond’s quality while remaining conflict-free and ethically sourced.

Lab Grown Diamond vs. Natural Diamond Price

Traditional diamonds are the most expensive choice. The process of discovering, mining, and shipping natural diamonds is resource-intensive; the high cost of bringing them to market has helped diamonds achieve their luxe reputation.

A lab grown diamond is perfect for when you want a real diamond but want to pay 30% less. Because the process of creating a diamond takes significantly less time and resources than mining a diamond from the earth, lab made diamonds cost significantly less than earth mined diamonds.

Like all natural diamonds, lab grown diamonds also come with their very own birth certificate (GIA Certification).

Since lab grown diamonds are optically and chemically the same as mined diamonds, they come with their own certification. Today, most lab created diamonds are certified by IGI, International Gemological Institute.

Additionally, these diamonds are being accepted and certified by the GIA, the Gemological Institute of America, which has developed sophisticated devices that are used to screen and identify the difference between natural diamonds and lab grown ones.
