  • Lab-grown diamonds can offer similar beauty, giving buyers more room in their jewelry budget.
  • Certification helps you understand what you are buying, including diamond origin and grading details.
  • Lab-grown diamonds offer more flexibility for custom jewelry, from diamond shape and size to ring design and details.
  • The right choice depends on what matters to you, from origin and tradition to budget, design flexibility, and resale considerations.

Choosing between a lab-grown diamond and a natural diamond can feel like a big decision. After all, you are not just choosing a stone. You are choosing something that is part of your surprise proposal, a special anniversary gift, a birthday gift, or something you want for yourself.

Natural diamonds have been part of the tradition for generations. Their rarity, geological history, and iconic “say-yes-with-a-diamond” classic engagement rings are a big part of what makes them appealing.

Lab-grown diamonds are also something that has been redefining luxury.

We at Lyra Jewels are working with lab-grown diamonds to craft jewelry that becomes part of your story. We create lab-grown diamond engagement rings and custom jewelry for people who want a real diamond while having more flexibility with their budget and design choices.

Let’s look at the differences in origin, price, quality, certification, sustainability, and resale value so you can decide which one makes the most sense for you.

What Are Lab-Grown Diamonds?

Lab-grown diamonds are genuine diamonds but have been produced in laboratories.

Instead of waiting for nature to do its work deep inside the earth, scientists create an environment in which the diamond can be grown.

There are two main methods used to grow diamonds:

  1. HPHT, or High Pressure High Temperature: This technique involves the use of very high pressure and temperature for growing a diamond using a carbon source and tiny diamond seeds.
  2. CVD, or Chemical Vapor Deposition: This is done through placing a diamond seed in a chamber full of carbon-rich gases. The carbon atoms then deposit on the seed to form a diamond crystal.

Both methods can produce gem-quality diamonds that are then cut and polished for use in jewelry.

Are Lab-Grown Diamonds Real?

Yes. Lab-grown diamonds are indeed true diamonds. They are different from diamond simulants such as cubic zirconia and moissanite. The structure of a lab-grown diamond is identical to that of a natural diamond with respect to its carbon crystalline structure and properties.

Origin is the true distinction. Natural diamonds have an origin that is formed by geologic means beneath the Earth’s surface. Lab-created diamonds are created through technologic means.

What Are Natural Diamonds?

Natural diamonds, of course, are those diamonds created deep inside the Earth through high temperatures and high pressure.

This process takes an incredibly long time for carbon atoms to take the form of a diamond crystal structure.

The formation of a diamond takes millions to billions of years. When the natural diamonds are mined, they are cut and polished in order to see the possibilities of their brightness and beauty.

This incredible journey through the Earth is a big part of why many people love natural diamonds. 

Why Do People Choose Natural Diamonds?

An answer to this could be different for everyone. As said above, for some, it is simply the idea of owning a stone that formed naturally inside the Earth long before it became part of their jewelry.

A natural diamond can represent:

  • A connection to Earth's geological history
  • Natural rarity
  • Traditional engagement ring symbolism
  • Family heritage and legacy
  • A more established resale market

Quality, Sparkle, and Diamond Certification

One question comes up again and again when people compare lab-grown and natural diamonds: Will they look different?

To the naked eye, a good-quality lab-grown diamond can look just like a natural diamond. Both can have the brilliance, fire, and scintillation people expect from a diamond.

The quality of either type is assessed using the familiar 4Cs of diamond grading.

The 4Cs of Diamond Quality

1. Cut

Cut plays an important role in how a diamond interacts with light. A properly cut diamond will appear brilliant and lively.

2. Color

Color means the amount of body color present in a diamond. On the traditional D to Z scale, the diamonds that have less color are given higher grades.

3. Clarity

Clarity refers to internal attributes called inclusions and external attributes called blemishes.

4. Carat

Carat is the term used to refer to the weight of a diamond. However, having a bigger carat weight does not necessarily guarantee that you have a better-looking diamond.

This is why two diamonds with the same carat weight can look and be priced very differently.

Why Does Certification Matter?

The diamond certificate provides documented details of the diamond that you wish to purchase.

The gemological laboratories, like IGI or GIA, issue certificates for the lab diamonds. The certificates can confirm if the diamond is lab-created and give all relevant details regarding the diamond.

At Lyra Jewels, we value certifications highly as they help ensure that the products we provide are of high quality. Our lab grown diamonds have the IGI (International Gemological Institute) certification. This assists eligible customers to make their purchases using certified diamond information.

Do Lab-Grown Diamonds Lose Their Sparkle?

No. Just because the diamond is grown in a laboratory setting doesn’t mean that it will get cloudy or that it will stop being a diamond altogether. Similar to the natural diamond, it can accumulate oil, dust, and other dirt on the surface. Regular cleaning helps keep it looking bright and sparkling.

Lab Diamond Price vs. Natural Diamond: What Does Your Budget Get You?

We observed that price is one of the biggest reasons people look into lab-grown diamonds in the first place.

Natural diamonds are limited, as they occur from natural deposits. So their journey from discovery to finished jewelry involves exploration, mining, recovery, processing, and distribution.

Meanwhile, the lab-grown diamonds follow an entirely different production model. They are grown in controlled environments, so their supply does not depend on natural occurrence like natural diamonds. 

As a result, lab-grown diamonds are generally more affordable than natural diamonds with similar characteristics.

Why Are Lab-Grown Diamonds Reasonable?

The price difference between natural and lab-grown diamonds is influenced by several factors, including:

  • Origin
  • Supply
  • Production methods
  • Mining and recovery costs
  • Market demand
  • Availability

Of course, the price of an individual diamond still depends on its own characteristics.

When comparing diamonds, pay attention to:

  • Carat weight
  • Cut
  • Color
  • Clarity
  • Shape
  • Certification
  • Setting
  • Brand

Looking at all of these factors gives you a much better idea of what you are actually getting for your money.

Are Lab Diamonds Worth It?

For many buyers, yes. One of the biggest benefits of choosing a lab-grown diamond is that a lower diamond cost can give you more room in your overall jewelry budget.

You might choose to spend that extra room on:

  • A larger center diamond
  • Your preferred diamond shape
  • Better clarity
  • A more detailed setting
  • Additional side stones
  • A custom design

This can be particularly useful when you are creating your customized lab-grown diamond engagement ring for a surprise proposal. Lab-grown diamonds work so well for custom jewelry. You have more flexibility to build a piece around your personal style and budget.

Ethics, Sustainability, and Transparency

Diamond mining in nature has advanced, focusing on ethics, working conditions, and management in the environment and in the supply chain.

Lab-grown diamonds have a different approach, since they are manufactured in the lab rather than mined in the traditional way of getting diamonds.

Potential Advantages of Lab-Grown Diamonds

For buyers concerned about the impact of traditional mining, lab-grown diamonds can offer:

  • A controlled production environment
  • A direct laboratory-based origin
  • No traditional diamond mining for the stone itself
  • Greater control over the production process
  • An alternative to mined diamonds

FAQs 

1. Are lab-grown diamonds real?

Yes, lab-grown diamonds are real diamonds. They have the identical crystalline structure of carbon atoms to that of diamonds found in nature. They are not to be confused with diamond simulants like cubic zirconia and moissanite.

2. Do lab diamonds pass diamond testers?

Yes. The diamond testers are made in such a way that they will test for features present in diamonds. However, they are not supposed to tell whether a diamond is natural or synthetic.

3. Will lab diamonds cloud or fade?

No. Lab-grown diamonds do not fade over time or lose their diamond characteristics. The appearance of both can become dull if their surface is coated with dirt, oil, or any other substance.

4. Are lab diamonds reasonable because they are lower quality?

Not. The disparity in price is mostly because of the source of the diamond, as well as its manufacture and availability.

5. Can you tell a lab-grown diamond from a natural diamond with the naked eye?

No. Both types of diamonds can look nearly the same to the naked eye. The origin of the diamond will only be known after conducting tests in the laboratory using specialized equipment.

6. Do lab diamonds have inclusions?

Yes. Lab-grown diamonds may also contain inclusions and various other internal features like natural diamonds. The clarity of the diamond is determined by considering these internal features.
