10 Best Lab-Grown Diamonds

Finding The Best Lab-Grown Diamonds

Best Lab-Grown Diamonds

When compared to earth-grown diamonds, the best lab-grown diamonds are the same in every way. They do have some noteworthy differences though, like being more affordable and certainly more ethical. 

Though they’re created in a lab instead of the earth, the same amount of pressure is applied, only, it takes weeks instead of millions of years to make them. That’s one of the reasons they’re much lower in cost than their chemical twins, and one that means your purchase comes without mining, unfair labor, and war. 

Need another reason? The best lab-grown diamonds look and feel like any other diamond does. It’s the cut and clarity that give a stone its sparkle, and with the right jeweler (like the 10 on this list), a jaw-dropping diamond piece can be on your finger, ears, wrist, or neck without the grand inquisition to find out where it came from. 

Whether you’re looking to uplevel your diamond obsession or are considering buying one for the first time, this list of the best lab-grown diamonds is an excellent place to start.

What Are Lab-Grown Diamonds? 

Best Lab-Grown Diamonds

Lab-grown diamonds are real diamonds. They have the identical chemical and physical properties to earth-mined diamonds. The only difference is their origin. Lab-grown diamonds are created in a laboratory, whereas natural diamonds are created by nature over millions of years. 

In addition, lab-grown diamonds are also sometimes called man-made diamonds, cultivated diamonds, or synthetic diamonds. Yet all of these terms refer to the same thing: a diamond that has been created in a lab rather than in the ground. 

Lab-Grown Diamonds: Creation Methods

The vast majority of lab-grown diamonds on the market today are made using one of two methods: high-pressure high temperature (HPHT) or chemical vapor deposition (CVD). 

The HPHT method recreates the conditions under which natural diamonds are formed underground. It starts with a small diamond seed, which is placed in a chamber with carbon under high pressure and temperature conditions. The result is a rough diamond crystal growing around the seed. 

The CVD method involves breaking down methane gas into its component parts: hydrogen and carbon. These elements are then deposited onto a small diamond seed in a low-pressure chamber, resulting in a thin film of carbon that gradually builds up around the seed until it forms a rough diamond crystal. 

Both of these methods can be used to create lab-grown diamonds that are optically, physically, and chemically identical to earth-mined diamonds. 

Why Lab-Grown Diamonds May Not Be Good For You

Lab-grown diamonds are real diamonds, but they’re not natural diamonds. They’re made in a laboratory by a process of superheating and cooling carbon. Lab-grown diamonds have the same optical, physical, and chemical properties as natural diamonds. However, they’re not as valuable as natural diamonds because they’re not as rare. 

Additionally, lab-grown diamonds are less expensive than natural diamonds, but they’re not always a good deal. Keep in mind that the price of lab-grown diamonds depends on the quality of the diamond and its size.

How To Take Care Of Lab-Grown Diamonds

Best Lab-Grown Diamonds

Because lab-grown diamonds are so new, there’s not a lot of information available on how to care for them. So, if you’re wondering how to clean your lab-grown diamond, here are some tips.

To clean dirt and grime from your lab-grown diamond, simply soak it in a solution of warm water and mild dish soap. Then, use a soft toothbrush to scrub the diamond gently. After that, rinse it well and dry it with a soft cloth.

If your diamond is particularly dirty or if it has build-up from body oils or perfume, you may need to use a stronger cleaning solution. You can make a solution of one part ammonia to 10 parts water. Soak the diamond in this solution for a few minutes, then scrub it with a soft toothbrush. After that, rinse it well and dry it thoroughly.

Most importantly, avoid using harsh chemicals or ultrasonic cleaners, as these can damage the surface of your diamond. Ultimately, lab-grown diamonds are durable and low-maintenance, and with proper care, they’ll last a long time.

Lab-Grown Diamonds: Properties

Lab-grown diamonds have the same physical, optical, and chemical properties as earth-mined diamonds. They have the same hardness (10 on the Mohs scale), refractive index, dispersion, specific gravity, and visual appearance. The only way to tell the difference between a lab-grown diamond and an earth-mined diamond is via advanced diamond-testing equipment.

Lab-Grown Diamonds Vs Mined Diamonds

Lab-grown diamonds are created through a process of sophisticated technological innovation. They’re physically, chemically, and optically identical to mined diamonds, yet they come with a host of benefits that make them a more attractive choice for many jewelry buyers. 

For instance, lab-grown diamonds are eco-friendly, humane, and often less expensive than their mined counterparts.

The process of mining diamonds can be extremely damaging to the environment. It involves clearing large tracts of land, which can lead to soil erosion and habitat loss. Luckily, lab-grown diamonds don’t require any mining, so they have a much smaller environmental footprint.

In addition, the diamond industry has been criticized for its ties to human rights abuses. So, lab-grown diamonds provide an alternative that’s free from such concerns. Because they don’t come from the earth, there’s no risk of them being associated with conflict or exploitation.

Furthermore, lab-grown diamonds tend to be less expensive than mined diamonds—although the exact price will depend on the size and quality of the stone. Because they don’t require the same level of investment in terms of land and labor, lab-grown diamonds offer significant cost savings that are passed on to the consumer.

For all these reasons, lab-grown diamonds are an increasingly popular choice for those looking for a beautiful, responsible piece of jewelry.

How To Shop For The Best Lab-Grown Diamonds

Best Lab-Grown Diamonds

Lab-grown diamonds have quickly become a popular choice for engagement rings and other fine jewelry. Thanks to advances in technology, these man-made diamonds are virtually indistinguishable from natural diamonds, but they typically cost less. 

When shopping for lab-grown diamonds, it’s important to keep the 4 Cs in mind. The cut, clarity, color, and carat weight all affect a diamond’s appearance and value. So, it’s best to work with a reputable jeweler to find a lab-grown diamond that meets your standards in all of these categories. 

FAQ

Best Lab-Grown Diamonds

Are lab-grown diamonds real diamonds?

Lab-grown diamonds are real diamonds. They have the same physical, chemical, and optical properties as diamonds that are mined from the earth. Lab-grown diamonds are also just as hard as natural diamonds, scoring a 10 on the Mohs scale of hardness.

The main difference between lab-grown diamonds and natural diamonds is how they’re produced. Lab-grown diamonds are created in a laboratory using either high-pressure high temperature (HPHT) or chemical vapor deposition (CVD) methods. 

Natural diamonds, on the other hand, are formed deep within the earth over millions of years through a process of extreme heat and pressure. 

Because lab-grown diamonds are produced in a controlled environment, they tend to be more flawless than natural diamonds. In fact, nearly all lab-grown diamonds fall into the ‘excellent’ or ‘very good’ categories on the four Cs scale of diamond quality (cut, color, clarity, and carat weight). 

So, if you’re looking for a diamond that’s stunning and pure, a lab-grown diamond may be the right choice for you.

What other names are lab-grown diamonds called?

Lab-grown diamonds are also known as man-made diamonds, cultivated diamonds, or synthetic diamonds.

How can I tell if my diamond is natural or lab-grown? 

Despite their different origins, both lab-grown and natural diamonds share the same physical and chemical properties. As a result, it can be very difficult for even a trained jeweler to tell them apart. 

The most reliable way to tell a lab-grown diamond from a natural one is through an assessment with specialized equipment. However, even then, it can be tricky to differentiate between the two. 

So, if you’re curious about whether that diamond ring is natural or lab-grown, your best bet is to take it to a professional for an assessment.

Which lab-grown diamonds are the smokiest? 

One popular belief is that because lab-grown diamonds are not exposed to the elements, they won’t become cloudy over time. However, this is not the case. Lab-grown diamonds can become just as cloudy as mined diamonds over time. The reason for this is that both types of diamonds are made of carbon. 

Carbon is a naturally occurring element that’s constantly interacting with its environment. And when diamonds interact with their environment, they can absorb impurities which can cause them to become cloudy. Therefore, whether a diamond is mined from the Earth or grown in a lab, it can become cloudy over time.

Final Thoughts

You’ve read all about the best lab-grown diamonds, what’s next? By now, you know what makes these ethical gems so attractive and the benefits of choosing them over their earth-grown counterparts. Which brand you choose depends on your personal style, budget, and most importantly, if they carry a piece that speaks to you.
