When it comes to the high-end, luxury jewelry world, many have asked about diamond alternatives that can add the same bling to their personal style. After all, top-quality diamond jewelry may be out of reach for some people due to its rarity and hefty price tag.
In the past couple of years, a new type of lab-grown diamond has appeared on the market. These manmade diamonds get their unique properties from being grown in a controlled environment instead of naturally formed by Mother Earth. There’s a lot of mystery around lab-grown diamonds, and it’s easy to understand why. Let’s take a closer look at what you need to know about lab-grown diamonds before you buy one for yourself or someone special.
What are Lab-Grown Diamonds?
Lab-grown diamonds are real diamonds that are created in a lab!
Growing diamonds in a laboratory sounds like something out of a sci-fi novel, but lab technology continues to advance at rapid speeds, making almost anything possible. Lab-grown diamonds are gaining popularity because they have many advantages. For example, due to their consistent growth and purity, lab-grown diamonds have excellent clarity and cut, making them a great option for engagement rings or any other piece of jewelry you want to last long.
Lab-grown diamonds are created by heating natural carbon into a graphite shape, but they can also be made from silicon carbide or aluminum oxide.
A typical process of creating lab-grown diamonds involves setting a carbon source inside an automated machine, where the machine injects carbon and other minerals, along with heat and pressure, to produce a diamond. Diamonds are made from carbon that has been subjected to high temperatures and pressures inside a laboratory. The process takes about two weeks. The machines are computer-controlled and programmed to control the temperature and pressure, as well as various other factors, throughout the growth process. The amount of time needed to produce a diamond depends on its size and shape. The first step in growing a diamond is to place a small piece of diamond seed material inside the machine. Next, the machine heats the piece of carbon inside the machine to create a high-pressure environment that forces the carbon to grow into a diamond.
The lab-grown process begins with a tiny diamond fragment, known as a seed crystal. This is placed in a cell inside a press, together with a metal catalyst, such as nickel or iron. A block of pure carbon, such as graphite, sits on top.
The first and original method, High-Pressure High-Temperature (HPHT), starts by planting the seed in pure carbon and placed in what amounts to an oven, under very high pressure and heat. The seed acts like a diamond template, and the carbon bonds to it layer by microscopic layer to create a rough diamond crystal which can then be cut and polished into its final brilliant form. The largest, whitest diamonds on the market are grown with this method.
The second method, Chemical Vapor Deposition (CVD), is more modern technology yet similar in that it also starts with a thin slice of a diamond seed.
That slice goes into a super-hot (though not as hot as HPHT) sealed chamber—a plasma reactor—filled with carbon-rich gas.
Then, those gases are ionized with lasers or microwaves to molecularly bond the carbon to the seed. Eventually, you guessed it, a freshly grown diamond.
How Should I Choose?
Natural diamonds are mined from the Earth, making them rare and more expensive than lab-grown diamonds. Lab-grown diamonds are manufactured in a laboratory under high-pressure and high-temperature conditions to produce diamonds that are similar to those found in nature. Lab-grown diamonds are more consistent in shape, size, and quality and may also be more affordable but less unique than natural diamonds. Both have attractive attributes when deciding the suitable rock for your personal jewelry.
Benefits of lab-grown diamonds
Consistent Quality - Lab-grown diamonds are consistent in quality, and you can easily choose the clarity level and shape you want.
Affordability - Lab-grown diamonds are more affordable because growing them is easier than finding them in nature. You can likely set a stone in your engagement ring or purchase other jewelry pieces that are more within your budget.
More Fun - Lab-grown diamonds are usually white or colorless, but they can also be yellow, blue, or even green, depending on the process. Rapid technological advancements mean new techniques will allow us to grow diamonds in various colors, enabling even more unique design options.
Limitations of lab-grown diamonds
Lack of Imperfection - While most lab-grown diamonds are colorless and have excellent clarity, they do not have the unique character of natural diamonds. The latter have natural imperfections that set them apart and make them special.
Lack of Rarity - Lab-grown diamonds are made in a lab and therefore are theoretically infinite in quantity. If one-of-a-kind rarity is what you are looking for, you should look into natural diamonds.
Lack of Geological History - Some people like the idea of wearing something that has been around for millions of years. This is because geological formations such as volcanoes and glaciers, as well as their impact on the environment, help tell the geological story of the Earth.
The 4C’s of Choosing a Lab-Grown Diamond
When it’s time to shop for a lab-grown diamond, it’s important to keep the fundamentals of diamond buying in mind.
In 1953, the Gemological Institute of America (GIA) invented the International Diamond Grading System and the 4Cs: cut, clarity, color, and carat weight. Lab-grown diamonds are most typically graded using this standard 4Cs method, which is considered the global standard for assessing diamond quality.
After all, the goal is to end up with a polished gem that you love for years to come.
The cut is perhaps the most significant factor in choosing a diamond. A diamond’s cut determines its brilliance, scintillation, and fire—all of which contribute to its value.
The clarity of a diamond is determined by the amount of inclusions. While synthetic diamonds can be manufactured with high clarity, clarity grade is particularly important when purchasing a lab-grown diamond.
The color of a diamond is just as crucial as its clarity. If a diamond is too yellow, it may not be the most attractive diamond in the world.
While natural diamonds are sold by their carat weight, lab-grown diamonds are sold by their carat number. This means that it’s difficult to compare the cost of lab-grown and natural diamonds since they are not graded in the same way.
The Bottom Line
The rise of social media has made it easier than ever to learn about new trends and buying habits. And the diamond market is no exception. With more people aware of their options, demand for lab-grown diamonds has increased significantly in recent years.
As the number of lab-grown diamonds increases, more designers and consumers are exploring new designs and using this new material. Since lab-grown diamonds have become a widely accepted option in the diamond market, there is no reason to avoid them. In fact, they are a suitable and attractive choice for anyone who is looking for a beautiful diamond at an affordable price.
