Lab vs natural diamonds.

Truth is… The average person will never know the difference, especially just by its looks. Give it to someone who has a PhD in diamonds (aka a GIA gemologist) and they may be able to notice a few variances. But it’s safe to say your soon to be fiancé’s bff will never be able to see a visual difference. In fact, the DNA of a lab diamond is exactly the same as a natural diamond. If you’re on the fence about which way to go, just know that both directions are good directions. It comes down to what’s a better fit for you. Lab diamonds tend to be cheaper than natural diamonds. Plus, Diamond Foundry lab diamonds are all made in the USA and are carbon neutral. This is one of the biggest reasons why we chose Diamond Foundry as our source for all lab diamonds. On the flip side, a story that’s rarely told about natural diamonds is the positive economic impact they have on locations where the mines are located. But more on that below.

So is a lab diamond a real diamond?

Yes. Lab diamonds are real diamonds. Lab diamonds have the same chemical composition and characteristics. They’re just simply made in a controlled environment rather than forming naturally from heat and pressure deep below the earth’s surface.

Diamond Foundry diamonds are made in the USA (The pacific northwest to be exact) at their state-of-the-art facility. Their state of the art technology simulates the conditions of how a natural diamond would form deep within earth. One of the big things that Diamond Foundry does is that they create their diamonds within a carbon neutral facility. This means that the carbon dioxide that would typically be created during the formation of a lab grown diamond is either captured or offset by planting trees.

What’s the best lab grown diamond?

We believe Diamond Foundry produces the best lab grown diamonds. Diamond Foundry’s diamonds are made in the USA in a certified carbon neutral facility. Each diamond is grown with solar technology which replicates the creation process to perfectly mirror a natural diamond.

Diamond Foundry’s diamonds are also graded by their own GIA certified gemologists to ensure you get the best value and the best diamond. This means Diamond Foundry's diamonds are graded more strictly when compared to some of the other lab grown diamonds on the market. Attention to detail is prioritized –all diamonds go through 1,300 inspections to ensure the quality of each diamond. After all, the last thing you want is to buy a diamond that is represented as one grade on paper and find out it is a different grade in real life.

3 Simple Reasons Diamond Foundry is the best lab diamond supplier.

1. Made in USA
2. The only lab grown diamond that is created in a certified carbon neutral facility
3. Ownership of the company is clear
“In this era of anti-money-laundering rules that mandate buyers know their customers, retailers increasingly want information about who owns lab-grown diamond companies, Mathuram says. Yet many growers are nontransparent, and some have had been linked to fugitive economic offenders, offshore entities, or the Chinese military. ”

What's the long term value of a lab diamond?

As lab grown diamonds are relatively new to the market, there’s no telling for certain what the long term value will be. On the other hand, natural diamonds hold their value because of the consistency of selling and reselling them on the market. For example, if you trade in a $5,000 diamond at J.R.DUNN for a bigger diamond you would get that $5,000 toward the bigger diamond.

If I buy a lab grown diamond, can I trade it up in the future?

We offer a 100% trade up guarantee on our natural diamonds since prices have remained pretty stable over the last decade. Since man made diamonds don’t have the pricing history that natural diamonds have, we currently don’t offer our trade up policy to lab grown diamonds at this time.

Are lab grown diamonds cheaper than natural diamonds?

Yes. Lab created diamonds are relatively cheaper than mined diamonds. The cost of mining is much more expensive than the technology used to grow lab diamonds. Since these man-made diamonds are created by Diamond Foundry, there are no extra markups. Right now, you can buy a lab grown diamond for 20-30% less than the price of a natural diamond.

Can you tell the difference between a created diamond and a natural diamond?

Nope. It is impossible to tell the difference with the naked eye since they are actual diamonds. Even a gemologist can barely tell the difference between lab grown and natural diamonds because they are carefully created under the same circumstances as a natural diamond. Unless the diamond is laser engraved, your jeweler probably won’t be able to see the difference between diamonds. However, the technology in testing devices is advancing rapidly and becoming more available to people. We predict that most jewelers will have the ability to test diamonds at store level in the near future.

For now, we recommend sending loose diamonds to an accredited lab to be correctly identified and certified. This is the best way, as of now, to determine whether a diamond is lab grown or natural.

Man made diamonds are better for the environment but are they better for people?

This entirely depends on the person buying the diamond. The clarity and quality of natural and lab created diamonds are exactly the same, so we recommend buying whatever agrees with your personal beliefs. There are various pros and cons that come with both options of diamond production.

Mining – known as the traditional way to produce diamonds –requires heavy machinery that digs deep below the Earth’s surface leaving significant environmental impacts. Lab grown diamonds are man-made under controlled conditions, however they do still use a good amount of energy to run the machines.

It’s been argued that the carbon footprint of a mined diamond vs. a lab created diamond may not be as different as people seem to think. This is why we chose to represent Diamond Foundry –the only carbon neutral supplier of lab grown diamonds at this time.

There are potential risks for people in the mining industry, whereas working in a lab to produce diamonds results in no safety hazards and an overall more eco-friendly setting. Many people have associated the natural diamond industry with environmental and human rights issues, though few have pointed out that mined diamonds can actually help people where diamonds are a natural resource. In many areas, diamonds provide jobs, education, and access to water and healthcare in some of the world’s poorest places.

So yes, it really all comes down to what you believe is morally correct after weighing the pros and cons of both options. To read more about the good diamond can do, visit: and

Why are lab grown diamonds not graded the same by GIA as natural diamonds?

“Lab-grown diamonds do not have the same range of color as mined diamonds and are generally grown to be as close to colorless as possible or are treated post growth to make them colorless or near colorless.”

As of July 2019, The GIA laboratory-grown diamond report is what’s now used to grade lab grown diamonds. Using new terms, they’ve created a criteria that more so lines up with a lab diamond versus a natural diamond. For example, a lab grown diamond graded as slightly included is like a SI1 or SI2 natural diamond. Because we are all familiar with the criteria used to grade natural diamonds, it's nice to have this comparison.

What are the labs that certify lab grown diamonds and why it matters?

  • Gemological Institute of America — GIA
  • International Gemological Institute — IGI
  • Antwerp World Diamond Center — AWDC
  • American Gem Society — AGS
  • Integration Gemological Institute — GSI

A certified diamond is important because it tells you the value of your lab grown diamond. It affects the price and tells you everything you need to know about your diamond.
