Iflab grown diamondsbecoming more and more popular, more and more customers are considering switching to this alternative product. Overall, these diamonds are more environmentally friendly and affordable than mined ones. In this article, we will cover the pros and cons of lab grown diamonds. My goal is to help you understand whether or not a lab grown diamond may be the right choice for you.

Without further ado, let’s get straight to the point:

1. The first benefit is cost saving. Lab grown diamonds are of course cheaper than their mined counterparts. The price difference is huge compared to natural diamonds. We can see a price difference of around 70% for some diamonds. This way you can save 70% of your money by choosing a lab grown diamond of equal values ​​or invest more and get a better looking, larger diamond.

2. The second advantage is environmental protection. Unlike natural diamonds, these diamonds are not obtained through mining, which is one of the main contributors to environmental degradation. Instead, they are made in the lab where environmental protection methods and practices are strictly adhered to.

3. Aside from cost savings and environmental benefits, lab grown diamonds are generally more visually appealing than their mined counterparts. Because in contrast to the latter, they result from aProceedingsfree from all possible impurities. Nitrogen atoms and other soil contaminants can affect the purity and clarity of natural diamonds and can easily degrade their aesthetic quality.

In addition, lab created diamonds are cheaper to produce compared to natural diamonds. You probably know that mining is one of the most expensive commercial ventures out there. Fortunately, this process involves none of that. Instead, only carbon atoms are extracted from carbon compounds and subjected to immense heat and pressure to form crystallized carbon particles that make up diamonds. The machinery and techniques required to do this are cheaper than those required to mine natural diamonds deep underground.

4. Finally, unlike their natural counterparts, lab grown diamonds are non-exhaustable and therefore sustainable. That's because carbon atoms, their main component, can be extracted from carbon dioxide, a gas that will never disappear from the atmosphere, at least as far as humans, animals, and plants exist on this planet. That is, as long as the means to extract and crystallize these atoms exist, one can always create artificial diamonds.

Disadvantages of lab grown diamonds

1. Unfortunately, growing diamonds in the lab can be quite energy intensive. This can result in high energy costs and place a significant financial burden on the company. However, as technology advances, so does energy consumption (which is good!).

2. While the cheaper price tags oflab grown diamondsCompared to natural diamonds, it can be a great deal for some buyers, but other customers might see it as less luxurious.

3. For diamond dealers who sell natural diamonds, lab grown diamonds are just bad for business. Think of it like dairy and soy milk: some customers prefer an alternative product, giving the dairy industry a smaller market share. Again, many customers prefer an environmentally friendly, larger, more beautiful lab grown diamond at a much better price.

4. Finally, many unsuspecting buyers have lost their hard-earned money buying lab-grown diamonds while thinking they were natural. It's a common scam. When purchasing a natural diamond, make sure this is the casecertified by a legitimate evaluation laboratorylike themIGI/AGS/FAMILY. I strongly recommend only buying from areliable seller. Remember that a cheap price may cost you later. As much as I love finding good deals, we need to draw the line when it's too good to be true.

Lab-grown diamonds: pros and cons (4)

What is a lab grown diamond?

A lab grown diamond, also known as a lab created diamond, is a diamond that is created in a lab. The process involves extracting carbon atoms from the air or any carbon-rich substance and gradually converting them into a crystalline form – crystallized carbon. This can take between 4-10 weeks.

Four techniques can be used in carbon crystallization;

  • High Pressure High Temperature Technology (HPHT).
  • Chemical Vapor Deposition (CVD) technology.
  • Detonation Synthesis Technology - involves the creation of nanometer-sized diamond grains through the detonation of carbonaceous explosives.
  • High Power Ultrasonic Graphite Treatment Technology - involves treating graphite with high power ultrasonics.

N/B: Of all the above techniques, HPHT and CVD remain popular. Nonetheless, lab-created diamonds made using the first technology are called "HPHT diamonds" and those made using the second technology are known as "CVD diamonds".

Unfortunately, creating artificial diamonds requires a lot of energy, which might explain why not so many countries are getting involved in this activity. Few countries such as China, US, Russia, South Africa, Ireland, Japan, Belarus, Sweden, Ukraine, Israel and France do so with China topping the list. According to theBBC, it is the most populous country in the world and produces 50 to 60 percent of artificial diamonds.

How are lab created diamonds made?

As I said before, lab created diamonds are made using different methodsHPHT and CVDbe predominant. In any process, a “diamond seed” and a carbon compound are key. First of all, the "diamond seed" is a crystalline form of carbon. It can be derived from a real diamond and most labs get theirs from their previously created diamonds (usually those with the most desirable characteristics)..The carbon compound, on the other hand, is a substance that contains a mixture of carbon and other chemical elements.

1. The high-pressure, high-temperature method

In the high-pressure, high-temperature method, the carbon compound is placed at the bottom of a belt press, cubic press, or split sphere press (BARS). Immense pressure (up to 730,000 PSI) and heat (over 2,550°F or 1,400°C) are then applied, causing it to melt completely. The melted carbon compound results in pure carbon residues, which are then fed to the diamond seed. This finally grows into a diamond after about 4-10 weeks.

2. The chemical vapor deposition process

In the CVD process, diamonds are grown from a hydrocarbon gas mixture and a diamond seed. This technique involves the use of a gas chamber, immense heat, a carbon-rich gas (often methane gas), and a sophisticated microwave or laser machine.

The diamond seed is placed in the gas chamber, which is then sealed and heated to approximately 800 degrees Celsius (1472 degrees Fahrenheit). After that, the gas is smoked into the sealed chamber and ionized into plasma with the microwave or laser machine. This process gradually releases the carbon from the gas. The resulting carbon atoms find and attach to the diamond seed and slowly build up, atom by atom, into a crystal diamond.

Are lab grown diamonds as good as natural diamonds?

The short answer is yes, because both share the same visual qualities and physical properties. In some cases, unlike the latter, lab grown diamonds can appear more sparkling than their natural counterparts due to the lack of impurities such as nitrogen atoms.

It all boils down to how the crystallization of the carbon atoms takes place in both cases. Remember that diamonds are basically made up of carbon atoms arranged in a crystalline structure known as "cubic diamond".

Lab-grown diamonds: pros and cons (6)

In both natural and artificial diamonds, carbon atoms have crystallized and arranged in the above structure due to immense heat and pressure. In the former case, however, this process occurred naturally after millions of years in an uncontrolled environment (hundreds of meters below the earth's surface). Consequently, it was affected by many problems including impurities such as hydrogen atoms.

Did you know?...

a) Soil is a material made up of several things including organic matter, minerals, living organisms, water and gas.

b) The organic matter consists mainly of nitrogen, hydrogen, oxygen, carbon and small amounts of sulfur and other elements.

c) Nitrogen is arguably the most common impurity in natural diamonds, accounting for up to 1% of the gemstone's mass.

However, in lab-made diamonds, the carbon crystallization process has taken place in a controlled environment (in the lab). State-of-the-art equipment ensures maximum precision and eliminates the problem of impurities getting into the gradually crystallizing carbon atoms.

Can an untrained eye tell if a diamond was created in a lab? Can a jeweler say that?

To answer the first and second question, no. This is because lab grown diamonds have similar visual characteristics and qualities to natural diamonds. This makes it almost impossible to tell the diamonds apart at first glance. However, lab-created diamonds have zero nitrogen atoms, while natural diamonds contain tiny amounts of these atoms that can only be detected by certain equipment. Instead of relying on the naked eye, professional gemologists and jewelers will use these devices to test the diamondsfluorescenceand tell whether the diamond was lab grown or mined based on the presence or absence of those atoms.

Lab-grown diamonds: pros and cons (7)

Is a lab grown diamond right for you?

The answer depends on a few factors. You see, lab created diamonds are just as real as their natural counterparts mined from the earth. Both have similar physical and chemical properties, i.e. the same shape,sizes,Colorgrades anddegrees of clarity.

However, lab grown diamonds tend to have a lower value compared to natural diamonds. If you don't care about the monetary value differences between the two choices, a lab grown diamond is just as good. If it is a piece of jewellery, you can use it to make a fashion statement just as much as a piece of jewelery made from mined diamonds.

The argument about the resale value of lab grown diamonds also doesn't hold water. Most natural diamonds lose 40% to 60% of their value the second you pay for them. Only rare diamonds, such as fancy blue, pink and red, will maintain or increase in value over the long term.

My point is, when you buy a diamond engagement ring, focus on making your loved one happy. A nice one money wise2000er Rolex Submariner, can give you a better return 🙂


Eventually, people are beginning to accept lab grown diamonds as real diamonds. Many celebrities no longer have a problem wearing jewelry made from these diamonds. The beauty of these sustainable diamonds is that they are just as real as their mined counterparts, with whom they share chemical and physical properties. Both consist of crystallized carbon atoms.

(Video) Why LAB grown diamonds better than MINED diamonds ?

In natural diamonds, carbon atoms have crystallized naturally beneath the earth's surface through exposure to intense heat and pressure over millions of years. With artificial diamonds, on the other hand, the atoms have been crystallized in the laboratory for a short period of between 4-10 weeks using special technologies. Both types of diamonds have their pros and cons as highlighted above.
