Advancements in technologies have enabled man to create diamonds in the labs at a tiny fraction of the time required by Mother Nature to do so.

Over decades of scientific research and continuous pushing of manufacturing boundaries, scientists are now able to create gem quality diamonds on a large scale basis to meet demands in the jewelry industry.

Now, I want to emphasize that lab grown diamonds have identical properties to traditionally mined diamonds. They are composed of the same material, require the same cutting/polishing process and exhibit similar physical/chemical properties to diamonds mined from the Earth.

Yep, that’s right and it gets even better.

Lab created diamonds can be made to the same level of clarity, color and brilliance as naturally mined stones. In fact, these man-made diamonds are almost indistinguishable unless they are subjected to specialized testing equipment like spectrometers and X-rays.

Benefits Of Buying Lab Grown Diamonds

For the consumer, there are 2 major benefits of buying lab created diamonds.

First of all, they leave minimal ecological footprints in the environment and are guaranteed to be conflict-free. This is because they are made in controlled laboratory conditions instead of being mined from the Earth with human-labor.

Secondly, you can easily save hundreds to thousands of dollars because of their significantly lower costs (about 20-30% less) compared to traditionally mined diamonds. This is good news for people with tight budgets as lab grown diamonds can help you get a better bang for your buck!

Brilliant Earth has a huge inventory of more than 800 lab grown diamonds of various carat sizes and shapes for you to select from. Click here to browse their diamond collection now!

A lab grown diamond is the real thing. As you can see from the video above, it can be just as beautiful as a mined diamond when the stone is cut to correct proportions.

If you are someone who wants to purchase an engagement ring that is produced in a socially and environmentally-friendly manner, man made diamonds offer a meaningful way to help you do that.

    Wow Paul. I just had a look at Brilliant Earth’s prices for lab created loose diamonds. They are charging prices very close to natural diamonds. How ridiculous. Gemstones have a metaphysical property that is equal to or created than the value of it’s three dimesional beauty. You can’t experience and enjoy this value with a lab created stone.

    Laboratory grown diamonds actually sell at approximately 20% cheaper than naturally mined stones. Due to technological limitations, I actually don’t see the prices of manmade diamonds coming down in near future. You will notice the price differences when buying large size diamonds. i.e. if a natural diamond costs $20,000, a synthetic diamond with similar specifications will cost around $16,000. If you are buying smaller diamonds, you probably don’t see such a huge absolute difference in costs.

    Get the diamond tested at another independent appraiser who has no interest in selling you diamonds. You could also bring it to another jeweler for a review. If it still comes back as a stimulant, bring this concern up with Brilliant Earth.

    Hi Paul, you mentioned Igi and egs being not as reliable as GIA and AGS…is there a reason Brilliant Earth doesn’t use GIA or AGS for their lab ratings? Thanks for your explanations- so much to learn.

  6. Paul Gian-
    November 11, 2015 at 9:08 am

    It’s a business decision by their suppliers to use IGI instead of GIA. In the current market, all commercial lab made diamonds have non-GIA reports.

    Hey Paul, I have a question and I wanted to thank you because I’ve been learning alot about diamonds! I went to a showroom of Brilliant Earth and my girlfriend loved a setting there and now I have to make the hard choice of getting a diamond. For sure, I’m getting a lab-grown diamond from them. The diamonds I have in mind are in the 900-1k dollar range with IGI certs.

    My question is about specific diamonds I want to purchase. I got the picture for 2 and they told me more pictures were coming. I LOVE that you put the video up on youtube because it really gives perspective. Anyways, here are my options.

    1714493Y .56 Carat, Round, Very Good Cut, F, SI2

    1746704Y .54 Carat, Round, Ideal, H, SI2

    1714682Y .48 Carat, Round, Very Good, H, VVS2 (no pic yet)

    1748890Y .51 Carat, Round, Super Ideal, F, SI2 (no pic yet)

    Is the SI2 rating risky? Do the diamonds look bad?

  8. Paul Gian-
    December 14, 2015 at 3:33 am

    Both diamonds aren’t cut well enough for me to recommend them. You can easily see this in the wonky contrast patterning displayed by both stones in the static images. Keep looking! Get ASET images as well because those will readily reveal cut issues in the diamonds.

    Hello Paul,

    My boyfriend and I have been together for a few years. We’re ready for that next big step, but limited budget wise. I’ve had my heart set on an emerald cut engagement ring, but have tried to prepare myself if he simply can’t afford it. He wouldn’t get one that didn’t have a decent color and high clarity. I would love to have the ring of my dreams, but know that the man of my dreams really doesn’t have the means.
    Now after some research, I am open to the idea of him giving me a lab grown diamond. You’re one of the few resources that seems to be knowledgeable and honest.

    I came across this item on eBay claiming to be a lab created diamond ring. I was hoping you could clarify if this listing is crap or not. 🙂

    I would also appreciate the names of other trustworthy suppliers of lab-grown diamonds.

    Thank you,

    Hi Kat,

    Hi Paul,

    I’ve heard that IGI grades are typically inflated compared to other grading labs. E.g. an IGI VVS1 might only be a VS1, an IGI F might actually be a G or H, etc. Is that a concern with Brilliant Earth’s lab grown diamonds?

  24. Paul Gian-
    April 28, 2016 at 3:37 am

    If you are talking about IGI appraisal documents or IGI reports where the loose diamond isn’t unmounted, what you say may hold true. Apart from that, IGI’s grading doesn’t vary so wildly as you mention (VVS1 to VS1 is a big difference) but they tend to be looser in the grading standards compared to GIA/AGS.

    An IGI SI2 may in fact be a I1 by GIA standards. I’ve seen this many times and this is one of the reasons why I don’t like buying diamonds with IGI reports.

    Unfortunately for consumers, at the moment most commercial lab grown diamonds are only graded by IGI. If you are fixated on a lab created diamond, consumers will just have to live with buying one with an IGI report.

    That said, GIA does grade synthetic diamonds but it isn’t meant for the market at large at the moment.

    Hi Paul!

    Great article! I stumbled across this as I was doing some research on lab created diamonds, and I noticed there are a number of different companies offering these stones online. You had noted Brilliant Earth was the largest online retailer for lab created diamonds, but companies like MiaDonna, Pure Grown, and Diamond Foundry seem to have just as much if not more selection on their websites (though it appears Pure Grown has recently transitioned to selling just in stores). Are these websites just as reputable as Brilliant Earth? Or would you recommend sticking with Brilliant Earth and not risking another site?


  26. Paul Gian-
    May 4, 2016 at 1:35 am

    Emily, the companies you mentioned like MiaDonna and Pure Grown are pretty decent businesses. I have no experience with Diamond Foundry and can’t say much about them. It depends on what you want and what you are looking for. Work with the vendor who can offer you sufficient details to size up a diamond and one that you are comfortable with.

    May 14, 2016 at 3:25 pm

    Hi Paul

    Fake is fake. Fake Rolex, fake cartier, whats next. A discount of 20% or so is a joke, should be sold at 20% of real stones. Resale value of next to zero. Opens more doors for some unscrupulous to sell as real. With your knowledge and education I am surprised you would endorse this.


  29. Paul Gian-
    May 15, 2016 at 6:41 am

    Nothing wrong with technology and man made diamonds. Unethical jewelers can rip you off with real/natural diamonds using misrepresented quality and dubious certificates. There’s nothing wrong with lab grown technology, it’s the selling process that the crooks use to scam consumers and this can happen regardless of the kind of products sold.

  30. WINNIE-
    May 23, 2016 at 10:35 pm


    I visited Brilliant Earth and requested to look at both lab made and mined diamonds. After reading your articles regarding GIA vs other certification reporting companies, I became a little skeptical when the sales associated advised that the mined diamond was GIA certified while the lab one was IGI certified. You mentioned that it’s a business decision – but what is the business decision exactly? I feel that it’s somewhat deceptive. Why won’t GIA certify lab made diamonds? And can I really trust the IGI certification because in another article you advised buying a diamond that is IGI certified because they are more lenient. Ultimately, I’m not sure how much money I’m saving if I’m getting a lower rated diamond because of the IGI leniency in rating. Your thoughts are appreciated! Thank you.

  31. Paul Gian-
    May 24, 2016 at 12:46 am

    As far as I know, GIA may not have the capacity to deal with large volumes of synthetic diamond grading (and maybe because of some other political issues with their current business of grading natural diamonds). It is how it is at the moment because IGI is the only company doing large scale grading of commercial lab grown diamonds. If you aren’t comfortable with them, stick with natural diamonds with GIA/AGS reports.

  32. Autumn Courtney-
    June 5, 2016 at 9:35 pm

    Love your article. I have never heard of “real” man made diamonds. I have done a lot of research and have some questions…
    There are so many sites online that clame to be “real” man made diamonds but really are polished CZ- Asha, nexus, betterthandisminds, Agape… I know you mentioned brilliant earth…. Besides them what are other companies that provide the real deal?? Pure grown diamonds? Any information is appreciated?
    If they have IGI certified is that all you need to look for? It’s just horrible how fraudulent this business is… I do not want a CZ with a silver costed ring for 1000’s…
    Any advice is appreciated!!

  33. Paul Gian-
    June 6, 2016 at 6:08 am

    I understand your frustration and admittedly, there’s an issue with how retailers are marketing their goods. Price is a good guideline for figuring out who’s selling what. In general, stick with an IGI report when it comes to buying a synthetic diamond. If there’s no grading report, you can be assured you are either buying a misrepresented product or a fake stone. Either way, it’s going to get you ripped off.

    And yes, pure grown diamonds sells synthetic diamonds.

    I was trying to buy from DiamondEarth and Diamond Foundry – both has poor customer service – if you try chating with them they are lost for days (Diamond Earth will not answer at all sometimes, just disappear). Finally I’ve chosen my favorit stones but ASET/idealscope images refused to be provided as well as marking of inclusions (Diamond Foundry). So I can not buy from them online without any idea on stone face up! Do you know one lab created company who can provide ASET and Idealscope?

    Hi Paul – thanks so much for your review here. I am looking at purchasing the following lab-made diamond: I requested the preview report which they have provided here: and following up with high-res photos for me to review next 2-3 days.
    Given the clarity, I think this lab diamond price seems to be discounted relative to peers to account for H Color, but cut proportions are excellent according to your spec. What I am concerned about is whether or not an IGI “H” could fall into an I or J with GIA, and would this be a noticeable flag for you? Will be set in a white gold setting. Your thoughts on this stone are appreciated, thanks!

  41. Paul Gian-

    Hi Paul

    Ive heard some reports that brilliant earth lab created diamonds and other lab created diamonds, whilst still maintaining sparkle, have less “fire” or none at all. Would you say that was your experience?
    Also, you mentioned that the lab grown do not retain value like the real deal, but can you elaborate? for instance would it lose all value once sold? or would it retain some value albeit much less than real diamonds?

    Any help appreciated!

  43. Paul Gian-
    July 21, 2016 at 3:11 am

    That largely has to do with cut quality and nothing of material issues. In this particular lab grown diamond, I would say it isn’t as bright another identical diamond with the best possible cut quality. In terms of fire, I think it does pretty well.

    Diamonds don’t retain value well regardless of being natural or synthetic. The problem with lab created gemstones is that nobody wants to pay a sum of money to buy them back due to supply and demand. That’s why offers to buyback are often low balled that it doesn’t make sense to sell them. If you want to purchase jewelry with the mindset of having them retain some value, I would recommend only buying gold (or pure metal) jewelry.

  44. Sara-
    August 17, 2016 at 12:13 am

    Have you heard of Diamond Foundry before? I am looking for man made diamonds and came across this site. Interestingly, after choosing a setting, some diamonds appear to be included in the price of the setting – it seems to resonance to be true.

  45. Paul Gian-
    August 17, 2016 at 1:39 pm

    Nope. Never heard of them before but I did check out their website on your behalf. The in-house grading report is definitely a red flag because of potential conflict of interest. Reliable jewelers don’t usually perform their own grading but instead, send the diamonds out to 3rd party neutral grading laboratories so that the rating of the diamond is impartial.

  46. Allison-
    September 21, 2016 at 7:30 pm

    Thank you so much for all your detailed blogs and information – especially on the lab created diamonds as this is what my boyfriend and I are looking into lately. There aren’t any stores where we live in Canada that sell them so we have been looking at Brilliant Earth since they seem to have the biggest online inventory.

    I read in some of the comments here that the IGI system used by Brilliant Earth to grade their lab created diamonds is slightly “off” from the typical GIA system for mined diamonds. Since we are buying it online, should narrow the search results to one level higher than normal then? i.e. if we wanted a G color, VVS2 (based on GIA standards), should be only search for F color, VVS1 lab created diamonds on the Brilliant Earth website to make sure to account for any differences in grading?

  47. Paul Gian-
    September 22, 2016 at 3:37 am

    The problem with IGI is that they are not consistent (they can sometimes go severely off or be on par with GIA’s grading standards). I won’t worry too much about clarity gradings as long as the diamond doesn’t have inclusions that can be seen by the naked eye. Make sure you get detailed images and cut information on the diamonds you shortlisted and you should be fine.

    Hey Paul-

    Thanks for putting together this great site! I’d like to get your opinion on this lab grown diamond from brilliant earth. Actual, ASET, and Idealscope images are in the link below:
    The proportions are:
    Total Depth Percentage 61.9 %
    Table Diameter Percentage 55.5 %
    Crown Height – Angle 15.5 % – 35.0 º
    Pavilion Depth – Angle 43.0 % – 40.9 º
    Culet Size NONE
    Girdle Thickness MEDIUM

    Seems like there might be some leakage under the crown and around the girdle, but the proportions also seem spot on. It’s .92c and selling for $3330. Thoughts? (It’s for an engagement ring).

    Thanks for your help!

    Have you ever heard of

  58. Paul Gian-
    November 15, 2016 at 6:07 am

    A “stimulated diamond” is not diamond. They don’t have the same chemical compositions are generally much softer on the Moh’s scale. Examples of these include Cubic Zirconium (CZ) which are typically found in costumer jewelry.

    A synthetic diamond is basically a lab grown diamond.

    Hi Paul,

    Like the others on here, I’ve really appreciated reading through all your comments; the diamond world seems quite a tricky one from a non-expert’s point of view!

    We’ve been looking in to lab grown diamonds after having them suggested to us by a jeweler. Although they may not be considered as special as natural diamonds (and although they may not hold their value), we love the fact that they are completely ethical (and cheaper!).

    We’ve been recommended a diamond and I would love to get your thoughts on it…..

    The report is here:

    While it’s no longer available, I had been looking at this lab-grown diamond at Brilliant Earth: The listing includes a IGI report and video of the diamond. It was listed at $2320 and has a HCA of 0.9, although it seemed to have some symmetry issues based on the video.

    Should I have pulled the trigger earlier? Or am I lucky to have missed out?

    Apart from Brilliant Earth can you please recommend other vendors. I usually like to compare companies, but in the case of man made diamonds its hard to find legit companies.

    If you are looking for lab grown diamond retailers, Brilliant Earth is as good as it gets for good selections and service standards.

    Hi Paul,

    Thanks for taking the time to answer all the inquiries from fellow diamond novices. I have been in the market for a 2CT diamond for a few months now in the 10K price point (So with that I understand come sacrifices)

    We recently purchased a GSI graded 2.17 CT round brilliant.

    It has one large inclusion on the edge and one slightly smaller one just outside the table, but is otherwise a very clear diamond. The description is as follows:

    Depth: 63.8%
    Table: 58%
    Crown: 16.4%
    Pavilion: 42%
    Girdle: med to slightly thick, faceted
    Culet: none

    Clarity, I2
    Color, E
    Fluorescence: Strong, Blue
    Symmetry: Good
    Polish: Good
    Cut: Very Good

    The biggest thing I’ve notice is the BRIGHT blue hue my diamond takes on in direct sunlight. So while still in my return window, I started looking at manmade diamonds and stumbled upon this from Brilliant Earth. I have requested photos and a 360 view of the actual diamond.

    My question is this: Do you think this manmade diamond would give me more “bang for my buck”?

    The GSI diamond is a terrible option. It is cut poorly (from its proportions) and the grading lab report isn’t reliable. You definitely overpaid for that stone. As for the Brilliant Earth diamond, the proportions look OK but that really means nothing without tangible images.

    I’m wanting a mans gypsy-type setting with a yellow lab created diamond (at least .75)

    I can’t find a dealer in my area that carries lab created diamonds & it’s difficult to imagine buying such a item online.

    I live in Silver Spring MD USA which is a suburb of Washington, DC.

    Any suggestions?

    Your best bet with lab created diamonds is to look for a well cut diamond at Brilliant Earth.

    Paul, so glad to see you are still answering questions! Truly a great gesture to people you don’t even know! I have two quick questions:

    1) What is the #1 vendor that you would recommend for naturally mined diamonds?

    2) Regarding value / maintaining value, how big of a factor for you is it that Brilliant Earth offers the Free Lifetime Diamond Upgrade for its real/natural diamonds but not its lab created diamonds? Neither are a great investment in terms of holding value, but in a way doesn’t the natural diamond hold its value if you can exchange it for 100% credit at any point in the future? And doesn’t this also kind of speak to Brilliant Earth’s lack of confidence in lab created diamonds’ value in the long term?

    2) Diamonds are just bad value for investments. Don’t think of them as such. If you want to invest, head to the stock market. The diamond industry isn’t the place for the average investor to make money from. The diamond upgrade is only applicable to buying another diamond. In that sense, it isn’t a 100% credit since you don’t get your money back. Anyway, such policies are common place and many vendors offer something identical.

    Are Nexus Diamonds synthetic or simulated? They say they’re the same as real diamonds. I’m so confused…

    Simulated = FAKE DIAMONDS.

    I’m looking to upgrade. My original company gives me entire purchase price of middle stone or I can use as trade up in another store or I can buy online and be stock w my other ring. Have you ever heard of Seems reasonable prices. But again if I use online to buy ring I cannot trade my old ring (paid $5k for old ring)

    Hi Paul,

    Thanks for the great website with very useful content.

    I’m looking to buy a lab diamond from BrilliantEarth. Can you comment on these 2 diamonds? From your prespective…would you consider them ‘great’ given their specifications? I’m leaning towards the bigger one because its bigger and thinking to the human eye there would be no other difference between the two except the size.

    Thank you!

    Sunny, this is the better cut diamond.
