Lab Grown Diamonds: Pros & Cons You Must Know

The word "lab diamond" is probably familiar, but have you ever wondered what it means? Lab created diamonds' physical characteristics, visual qualities, and chemical makeup are identical to those of genuine diamonds, making them "real" diamonds. The contemporary alternative to mined diamonds, man made diamonds combine the beauty of precious stones with cutting-edge technology. Consider carefully the pros and downsides of these gems—cultured or synthetic diamonds—as you explore your jewelry selections. Their chemical makeup and visual attributes are identical to their natural equivalents, but the fact that they were created in a lab is a major red flag.


Read on for a rundown of the pros and cons of lab grown diamonds and information on how they are made. This data may help you decide whether a synthetic diamond is the best option for you.

How Lab Diamonds are Made

Although GE made the first man made lab diamonds in 1954, manufacturing lab produced diamonds of gem grade required years of refinement. Making a laboratory grown diamond isn't that dissimilar from making a real diamond. One occurs deep under the planet's surface, while the other occurs in a controlled environment. Lab manufactured diamonds are made the same way as natural diamonds, using the same high temperatures and pressures that transform carbon into diamonds.


High-Pressure High Temperature (HPHT) and Chemical Deposition are the two methods manufacturers use to generate laboratory created diamonds. The following is a rundown of each method:

HPHT Diamonds

In this process, a diamond "seed" is mixed with carbon. A hot, pressurized environment transforms a tiny, naturally occurring diamond particle into a diamond seed. Actually, the diamond seed and carbon are subjected to very high pressures of one million pounds per square inch and temperatures exceeding 1,300 to 1,600 degrees Celsius. These circumstances resemble the intense heat and pressure naturally occurring in diamonds as they originate in the ground. After cooling, carbon encases the man made diamonds seed.

CVD Diamonds

A diamond "seed" is the starting point for this chemical vapor deposition method. Because the seed affects the final lab diamond, choosing the strongest, most brilliantly colored, and clearest natural diamond possible is essential. The CVD procedure of lab-created diamonds involves placing the diamond seed in a vacuum chamber loaded with gases rich in carbon. The vapors are transformed into "plasma" by subjecting it to temperatures above 1,000 degrees. The lab cultured diamonds' layers are "built" with the aid of this plasma.

Lab Created Diamonds Pros

Lab manufactured diamonds are less expensive, more environmentally friendly, and a more moral choice than mined diamonds. When did this happen? This jewel's allure originates from the fact that, unlike the mining of genuine diamonds, it does not disrupt the habitats of animals. Since this is not the case with traditionally mined diamonds, they are far better for the environment.


Deforestation, water contamination, and a significant carbon footprint are some of the negative environmental impacts of the diamond mining industry, whether the mines are located underground or in open pits. Mining also has the potential to harm ecosystems and endanger animals, which has repercussions for biodiversity and local populations. Laboratory grown diamonds, on the other hand, are less harmful to the environment since they are made in a controlled environment.


Their generation process minimizes energy use and carbon emissions while eliminating harmful mining techniques. However, even with improvements in energy efficiency, the creation of lab grown diamonds is still an energy-intensive process, and the sustainability of these diamonds might differ from one lab to the next. Consequently, jewelers who value ethics in their business and their clients have lab cultured diamonds as a more sustainable alternative.

Ethical Sourcing

Unlike mined diamonds, lab produced diamonds are not involved in unethical actions and do not come from a conflict zone. For buyers worried about the diamond industry's influence on society, they provide an honest and moral alternative.


Compared to mined diamonds, lab cultured diamonds are often less expensive. Consumers benefit from cost reductions made possible by a regulated and efficient manufacturing process.

Color Choices

One advantage of man made diamonds are the ability to manufacture diamonds in unusual hues that could be hard to obtain in real diamonds. Customers now have more color selections to choose from. To manufacture colored lab-grown diamonds, scientists use cutting-edge technical techniques that are a near-exact replica of the diamond-forming environment in nature.


Trace elements, such as boron for blue and nitrogen for yellow, are added to these lab manufactured diamonds while they are still developing, giving them their bright hues. This permits an endless variety of colors, in contrast to genuine diamonds. Due to the regulated environment in which they are generated, laboratory created diamonds often display remarkable clarity with no internal faults or inclusions, in contrast to naturally occurring diamonds.

More Designs and Shapes

The development of lab grown diamonds has stimulated innovation in the diamond industry due to the high-tech methods involved in their creation. This never-ending quest for perfection has resulted in practices that are both sustainable and efficient. The size, shape, and color of man created diamonds may be altered to suit individual tastes. Diamonds may be customized to meet the specific needs and preferences of each buyer.


New avenues for jewelry design may be explored using lab made diamonds. Given the wide range of sizes and hues available, designers can unleash their creativity and create one-of-a-kind designs that would be impossible with real diamonds.

Lab Created Diamonds Cons

There are still some risks to think about when purchasing laboratory grown diamonds. Factors to consider are their future worth, popularity, and market saturation. Before making a final choice, it's wise to consider these points.

Less Value

The resale value of wholesale lab diamonds is often lower than that of real diamonds. This is due to the common belief that real diamonds represent enduring beauty and heritage. Because of this, your investment can lose value faster.


Accordingly, lab diamonds for sale simply have a better quality level from a "4 Cs" standpoint (the "4 Cs" is the grading scheme that both mined and synthetic diamonds are evaluated according to). Whereas the quality of naturally occurring diamonds is determined by Earth's environment, loose synthetic diamonds allow manufacturers to manipulate the stone's quality directly.

Insurance Issues

Man made lab diamonds aren't always covered by standard insurance policies. Before you depend on homeowners insurance or a comparable policy to safeguard your valuable jewelry from calamities, carefully examine the policy's coverage details regarding jewelry.


Before making a final decision, you should consider the benefits and drawbacks of both lab and natural diamonds. Consider your financial situation, whether you believe in conflict-free diamonds, and the effects of diamond mining on the environment.


Since man created diamonds are usually 40-95% cheaper than natural diamonds of the same size and grade, they have gained immense popularity in the diamond business for their affordability and exceptional quality.


It is important to choose a reliable manufacturer, whether you like lab-grown or natural diamonds. After doing your homework, choose a jeweler or store that sells diamonds verified by reputable gemological organizations like the Gemological Institute of America (GIA) or the International Gemological Institute (IGI).
