How Are Lab Diamonds Made?

How Are Lab Diamonds Made?

Lab diamonds are made in controlled laboratory environments using today’s most advanced technologies that duplicate the growing conditions of mined diamonds or those produced by the earth.

Lab diamonds have the same optical and chemical properties as mined diamonds. The sparkle is the exact same. The only difference is their origin.

Diamonds Beyond the 4C's

Our ultra-curated diamonds are unsurpassed for their quality, beauty, and make



Color evaluation is based on the absence of color in white diamonds. Our center stones are exclusively colorless to near colorless and all of our jewelry is colorless.



A well-cut diamond reflects and refracts light for maximum brilliance. Our diamonds are ‘Excellent’ cut—the highest grading a diamond can receive.



Carat indicates the weight of a diamond, not the size. Our lab diamonds are always cut to maximize the overall beauty in any given price range.



Clarity refers to the absence of inclusions in a diamond. We offer VS+ clarity lab diamonds with no visible imperfections to the naked eye.

Many lovers of diamond jewelry wonder “how are lab grown diamonds made?” Let’s discuss the unique and innovative creation process.

How Are Lab Grown Diamonds Made?

First and foremost, lab diamonds are real diamonds. Lab diamonds are created in controlled laboratory environments using advanced technologies that replicate the natural growing conditions of diamonds formed within the Earth's depths. By duplicating the same elemental forces that shape mined diamonds, lab grown counterparts possess identical optical and chemical properties. Their mesmerizing light performance, captivating brilliance, and scintillating fire are indistinguishable from naturally sourced counterparts. It’s important to note the only distinguishing factor lies in their origin, as lab diamonds are created with human ingenuity and innovation rather than the geological processes that shaped their earthly counterparts. If you’re curious about how lab-grown diamonds are made, then you may also wonder if they test as real diamonds. Keep reading to find out. 

Do Lab-Grown Diamonds Test Positively as Real Diamonds?

The simple answer is a resounding "yes!" Lab diamonds register as authentic diamonds when subjected to diamond testers, leaving no room for uncertainty. Despite their untraditional origin, lab diamonds are unequivocally real diamonds, possessing identical chemical and optical properties to mined stones. The discerning eyes of expert gemologists are unable to detect any distinction between lab-grown diamonds and natural diamonds through visual examination alone. It’s only through the utilization of specialized equipment capable of detecting subtle dissimilarities in trace elements and crystal growth can a gemologist make a distinction between lab-grown and mined diamonds.These lab-grown stones epitomize the remarkable achievements of scientific innovation, seamlessly offering the beauty and magnetism of diamonds while being a sustainable and ethically sound alternative to mined diamonds.

Important Distinction: Lab Diamonds Are Not the Same as Moissanite

Lab diamonds and moissanite are distinctly different when it comes to their composition and properties. Moissanite is not a form of diamond; it is a separate mineral altogether. These two gemstones possess distinct appearances and hardness ratings that set them apart.

At Jean Dousset, we exclusively focus on lab diamonds and do not incorporate moissanite into any of our jewelry or engagement ring designs. We pledge to hand-select diamonds solely from the top 1% of lab diamonds available around the world. By prioritizing lab diamonds, we guarantee the exceptional quality, unmatched brilliance, and long-lasting beauty that our discerning customers expect and deserve. All so you can acquire what you desire without compromise. Next, we’ll cover the unique and innovative growing processes. 

How Are Lab Diamonds Made in the Lab & What Are the Growing Methods?

In the laboratory, lab diamonds are cultivated through two prevalent methods: High Pressure High Temperature (HPHT) and Chemical Vapor Deposition (CVD). While both methods have their merits, CVD has emerged as the preferred process for producing high-quality, authentic diamonds. At Jean Dousset, we exclusively work with lab diamonds grown through the CVD process for all of our diamonds over one carat, ensuring exceptional quality and beauty with every stone.

The process of growing lab diamonds involves a unique series of steps. It starts with a slender 'seed' diamond carefully positioned within a chamber, where it is subjected to highly elevated temperatures. Subsequently, a gas mixture enriched with carbon is introduced into the chamber. Through the process of ionization, the molecular bonds of the gasses are broken down, enabling the pure carbon atoms to affix themselves to the diamond seed. Over time, as the carbon accumulates, it forms atomic bonds with the seed diamond, ultimately resulting in the formation of a new and larger (and beautiful) diamond. Like magic, lab grown diamonds exhibit indistinguishable resemblance to naturally occurring diamonds.

The growth period for lab diamonds can vary individually for each stone, typically taking approximately a month to cultivate a 1 carat CVD diamond. This intricate process requires precision, expertise, and advanced technology to ensure the creation of diamonds that possess the same brilliance, clarity, and durability as mined diamonds.

At Jean Dousset, we are devoted to moving forward and pushing the boundaries of what’s possible with jewelry. Hence, we exclusively work with lab diamonds that have been grown using the CVD process for all of our diamonds over one carat. By selecting lab diamonds cultivated through this advanced method, we guarantee the high-quality and beauty that our customers expect.
