Lab-grown diamonds are real diamonds produced in a controlled laboratory environment.
Chemically, physically and optically, these diamonds are identical to natural diamonds, with the same hardness, luster and sparkle.
Unlike natural diamonds, which are formed over billions of years deep in the Earth's mantle, diamonds can be created in a lab in just weeks to months.
Lab-grown diamonds start as tiny carbon seeds and are created by two main methods:
HPHT – mimics the natural conditions of the Earth: immense heat over 2,000 degrees and tremendous pressure create a diamond crystal around the seed.
CVD – A thin diamond seed is placed in a vacuum chamber with carbon-rich gases. When heated, the carbon breaks down and deposits layer by layer until a diamond is formed. Sometimes heat and pressure treatment is added to improve quality.
Both methods produce real diamonds that are completely identical to those mined from the earth – with the same durability, quality, and brilliance. The only difference is in the production time and growth patterns, which cannot be detected by the naked eye but only by experts.
Are lab-grown diamonds real?
Yes, lab-grown diamonds are just as real as natural diamonds. There are quite a few myths surrounding lab-grown diamonds, here are some of the most common:
"Lab-grown diamonds are fake"
Not true. Lab-grown diamonds are chemically, physically, and optically identical to natural diamonds.
"Lab-grown diamonds look different from natural diamonds"
Not true. With the naked eye, even experts cannot tell them apart without special equipment.
"Lab-grown diamonds are less durable"
Not true. Lab-grown diamonds have the same hardness (10 on the MOHS scale) as natural diamonds.
"Flawless lab-grown diamonds"
Not true. Like natural diamonds, lab-grown diamonds can also have inclusions.
The only real difference is where they come from : lab-grown diamonds are grown in a controlled environment in a lab, while natural diamonds are formed deep within the Earth over billions of years. Other than that, they are completely identical and are considered 100% real diamonds.
Advantages of lab-grown diamonds
Lab-grown diamonds are an attractive option for luxury jewelry buyers—and the following benefits explain why.
Support for sustainable practices:
Lab-grown diamonds are a responsible choice, as they are grown using precision technology that does not involve mining. Their production typically has a lower carbon footprint and is less damaging to the environment—a thoughtful choice for conscious consumers.
Identical to natural diamonds:
Lab-grown diamonds are chemically, physically, and optically identical to diamonds mined from the earth.
Variety of colors:
Lab-grown diamonds are easy to create in unique, brilliant hues like pink, yellow, and blue. These stunning color options are often more affordable than their natural counterparts, giving you the creative freedom to choose a diamond that matches your personal style.
Value for money:
Lab-grown diamonds are generally cheaper than diamonds mined from the ground of the same size and quality, so you can choose a larger or higher quality diamond for the same budget—an attractive solution for those seeking luxury at a more affordable price.

Is it possible to distinguish between lab-grown diamonds and natural diamonds?
To the naked eye, lab-grown and natural diamonds look identical. Only gemologists can detect tiny differences using specialized equipment and high magnification:
Think you can identify?
Test your eyes with six pictures of diamonds side by side and see how well you can do.
The center diamond in the top row and the left diamond in the bottom row are natural diamonds. The other four are lab-grown diamonds. For most people, they are almost impossible to tell apart with the naked eye — And that's part of what makes both options so appealing.
