The global lab-grown diamond market was valued at $22.45 billion in 2022 and is projected to grow to $37.32 billion in 2028. The popularity and demand for lab-created diamonds have increased exponentially in the last decade. And it is showing no signs of slowing down. The good news is that the lab diamond industry is able to meet this growing demand and offer more to diamond jewelry lovers. One of the key reasons for this is the process of growing diamonds is faster and more sustainable than natural diamonds. It takes less time and produces high-quality diamonds. So how are lab-grown diamonds created? And how long does it take to make diamonds in laboratories? These are the questions we answer in this blog.
Lab-made diamonds are real diamonds that are made in laboratories. Lab-created diamonds are made by exacting the same methods and processes with which diamonds are created under the surface of the earth. Lab diamonds follow the same grading standards as mined diamonds. The popularity and demand of lab-grown diamonds are growing, and with it, variety and customization options.
The production of lab-made diamonds is a highly controlled and accurate process that necessitates modern technology and specialized equipment. Diamonds made in laboratories are as real as diamonds that form under the surface of the earth. Before we get into how long it takes to make a lab diamond, let’s understand the different methods of making lab diamonds.
There are two methods to grow diamonds in laboratories:
Chemical Vapor Deposition (CVD)
High Pressure, High Temperature (HPHT)
Both of these methods provide diamonds of the same quality.
In the CVD method, a good-quality diamond seed is placed in a chamber. The chamber is heated, and gas is added to the chamber. Here, the gas-carbon atoms are broken down. These atoms combine with the diamond seed and form more crystals, leading to the formation of the diamond.
The HPHT method of making lab diamonds has been in use since the 1950s. In this process, a diamond seed is placed on a carbon material. The seed then goes through high temperatures and pressure, exacting the process that forms diamonds under the surface of the earth. This process creates diamond crystals. Once cooled, it forms a diamond. This process has seen many advancements over the years as the demand for lab-grown diamonds keeps increasing, necessitating methods that can produce diamonds in large numbers and in less time.
Both of these methods take almost the same time to produce lab-grown diamonds, but the CVD method is faster. Depending on the size and quality of the diamond being formed, both CVD and HPHT processes can take anywhere from a few weeks to a few months to complete. The CVD method is often speedier and can make a small diamond in as little as two weeks, whereas the HPHT procedure can take up to three months to create a larger diamond.
After the lab-grown diamond is made, it is graded to ensure that it fulfills the same requirements as natural diamonds. Cut, color, clarity, and carat weight are the same criteria used to assess lab-grown diamonds as they are for natural diamonds. Depending on the size and quality of the diamond, this process can take several days to a week.
Going by the increasing preference for lab diamonds, they are an excellent substitute for naturally mined diamonds. Diamonds manufactured in a lab are not only more environmentally friendly and sustainable, but they are also less expensive than natural diamond jewelry. For example, you can buy the best lab-grown diamond engagement ring for the same price that you would pay for a mined diamond. Moreover, you can’t be assured about the traceability of the mined diamond.
The decision to purchase a lab-made diamond is ultimately a personal one. If you like the look of diamonds but are afraid to purchase them because mined diamonds do not reflect your personal values, a lab-created diamond may be the answer you've been waiting for. These natural diamonds are becoming a more affordable luxury that you can enjoy with the peace of mind that mined diamonds cannot provide.
