Bottom line recommendation
While the IGI may not be as stringent as the GIA in grading natural diamonds, it offers a comparably thorough system for lab-grown diamonds. Both labs are deemed reliable, but the demand for GIA-graded diamonds has seen a spike since 2023, mainly because of their reliable branding.
Price-wise, the disparity between the two is negligible, contingent on the retailer. The premium for GIA-certified diamonds typically ranges from 0.5% to 4%, hardly a major difference. As long as you’re purchasing from a trustworthy seller, you’re in good hands:
For the broadest array of 20,000 GIA lab-grown diamonds, I recommend this reputable seller. You can find a stunning 2.01 carat D VVS2 such as this one at a competitive rate. They sell IGI too, so you can compare both and see what you like more.
For the most extensive selection of both IGI and GIA lab-grown diamonds, check this retailer (my personal favorite). It generally provides more options at more affordable prices. For instance, you can pick a 2.00 carat D VVS2 for $3,500 here (a 10% price difference).
The key difference between IGI and GIA certification for lab diamonds lies in the disclosure of growth methods. IGI certificates provide detailed information about whether the diamond was created using CVD or HPHT techniques, and they disclose any post-growth treatments. GIA certificates, while highly respected, don’t reveal these specifics about the growth process or treatments. This makes IGI certificates more informative for consumers interested in the technical aspects of their lab-grown diamond’s creation, while GIA focuses more on the final product’s characteristics.

When it comes to lab-grown diamond certifications, there is a range of labs that grade the quality of the diamond. The most reputable and respected certifications are done by the IGI (International Gemological Institute) and GIA (Gemological Institute of America). These two labs use strict grading standards to determine how well a diamond reflects light, cut, color, size, and carat weight. In this blog post, we will cover what IGI and GIA certificates are all about!
What is a lab-grown diamond certification?
Alright, let’s break it down. A lab-grown diamond certification is like a diamond’s report card from a neutral third party. These guys shouldn’t have skin in the game when it comes to how much your diamond sells for – they’re just here to tell it like it is.
These diamond labs put your sparkler under the microscope and give you the lowdown on all its characteristics. Diamond laboratories play a crucial role in the certification process, evaluating diamonds based on the 4Cs and ensuring the independence of the grading from the sales aspect. We’re talking about the famous 4 C’s here: carat, color, clarity, and cut. They’ll scrutinize every facet, measure every millimeter, and then compile all that info into a neat little package – your diamond’s certificate.
Now, why should you care about this piece of paper? Well, let me tell you, it’s your good friend when you’re diamond shopping. It’s like having a diamond expert in your pocket, helping you compare apples to apples (or should I say, diamonds to diamonds?). Without it, you’re basically taking a shot in the dark.
Do lab-grown diamonds have a certification?
Whether your diamond was born in the earth’s crust or in a lab, it can (and should) come with a certificate. Some jewelers might try to tempt you with uncertified diamonds at a lower price, but trust me, that’s a gamble you don’t want to take. Without certification, you can’t be sure if your diamond is the real deal or if you’re getting scammed. Lab diamond certification provides crucial information about the stone’s quality, including attributes such as cut, clarity, and color, and highlights the variability in grading among different laboratories.
With a certificate in hand, you can make an informed decision and effectively compare similarly graded diamonds. For instance, you can determine if a 1.54 carat F VS1 with Hearts and Arrows cut for $2,090 offers better value than a 1.50 carat D VS1 with ideal cut for $1,800. The certificate provides you with detailed information about each diamond’s characteristics, allowing for precise comparisons.
When it comes to lab-created diamonds, IGI is currently the leading certification provider. They offer comprehensive information on clarity, color, and other important attributes. GIA has also recently begun certifying lab-grown diamonds, but their certificates are less common and often more expensive. As a result, most retailers prefer IGI certification for lab-grown diamonds due to its accessibility and cost-effectiveness.
What should you look out for with lab-created diamond certification?
Here’s a little insider secret – not all diamond certificates are created equal. Different labs might grade the same diamond differently, so you can’t always compare prices based on certification alone. My advice? Go for a diamond with a reliable certificate, but don’t forget to use your own eyes too. Review the diamond closely to ensure its quality and authenticity.
It’s important to know that there are numerous diamond grading labs worldwide, and each has its own unique approach to evaluating and describing diamonds. These differences can be quite significant, which is why understanding the reputation of various certificates is crucial when you’re in the market for lab-created diamonds.
Let me give you a classic example. A well-respected grading lab might assess a diamond as F color, which would naturally affect its value. But here’s where it gets tricky – a seller looking to maximize profits might seek out a less reputable lab that’s known for being more lenient in their grading. This less scrupulous lab might assign a higher D color grade to the same diamond, artificially boosting its retail price.
This kind of discrepancy is exactly why it’s so important to choose a diamond with certification from a trusted, established grading lab. It’s not just about having a certificate – it’s about having one you can rely on. When you’re making such a significant purchase, you want to be confident that you’re getting exactly what you’re paying for.
Why does detailed grading matter?
Detailed grading is like getting the director’s cut of your favorite movie – it gives you the full picture. For lab-grown diamonds, IGI goes the extra mile. They don’t just tell you about clarity and color; they spill the tea on how your diamond was made.
Let’s say you’re eyeing a 1.30 carat radiant lab diamond. An IGI certificate won’t just tell you it’s E color and VS1 clarity. It’ll also dish on whether it was made using CVD or HPHT methods. This kind of intel helps you make smarter comparisons between lab-grown diamonds. It’s like being able to peek behind the curtain of each stone’s creation.
Is the diamond grading system too subjective?
Now, here’s where it gets juicy. Is the diamond grading system too subjective? Well, it’s not as black and white as you might think. Even with all our fancy grading standards, there’s still a human element involved.
Here’s the deal: we don’t have some all-powerful diamond authority decreeing exactly what a “VS2” clarity or an “H” color should look like. It’s more of a consensus thing. Different labs might look at the same diamond and come up with slightly different grades. But – and this is key – what matters is consistency within each lab.
If Lab A always calls a certain level of color “H,” and Lab B consistently calls that same level “I,” then at least you know what you’re getting with each lab. But just because a lab is consistent doesn’t mean it’s spot-on accurate or 100% trustworthy. Some labs might be consistently more lenient in their grading.
That’s why choosing a reputable lab is so crucial. For lab-grown diamonds, IGI is currently the go-to. They offer consistent, detailed grading that you can rely on.
How do you compare diamonds that have the same certificate?
Comparing diamonds with the same certificate is like comparing apples to apples – it makes your job a whole lot easier. If you’re looking at two IGI-certified diamonds, you’re working with consistent information. But don’t just rely on the paper – your eyes are your best tool! Here’s how to really dig in and compare:
Get a good look: Inspect both diamonds from the top view and the side view. Check if the color matches what’s on the certificate. Sometimes, a diamond graded as ‘F’ might look whiter than another ‘F’ diamond to your eyes.
Play detective: Grab a diamond loupe if you have one (or ask the jeweler for help). Try to spot any inclusions mentioned in the clarity section of the certificate. Can you see what the grader saw? This can help you understand if one VS1 diamond is “cleaner” than another.
Size matters… or does it? Compare the carat weights on the certificates. Then ask yourself – can you actually see the difference? Sometimes, a 1.27ct and a 1.51ct diamond might look pretty similar to the naked eye, especially in certain cuts.
Let there be light: This is the fun part! Which diamond has more sparkle, fire, and brilliance? The certificate can’t tell you this, but your eyes can. Tilt the diamonds, move them under different lights. The one that dances more might be the winner, regardless of what’s on paper.
Measure up: Check out the measurements on the certificate. Each diamond shape has ideal proportions that maximize light performance. If you’re not sure what to look for, don’t hesitate to ask an expert to interpret these numbers for you.
For example, let’s say you’re torn between a 1.31ct GIA-certified F VS1 lab-grown diamond for $1,270 and a 1.54ct IGI-certified F VS1 lab diamond for $2,090. On paper, they’re similar except for carat weight. But when you look closely:
The 1.27ct diamond might appear brighter and have more fire, despite being smaller.
The 1.51ct diamond could have a visible inclusion that the 1.27ct doesn’t, even though they’re both VS1.
The larger diamond might look disproportionately bigger, giving you more visible diamond for your buck.
Remember, the certificate is a great starting point, but your eyes (and brain!) are the ultimate judges. Don’t be afraid to take your time, ask questions, and really examine each diamond.
Consider the price over the certification
Listen up, because this is important: don’t get so caught up in the certification that you forget about the price! The price should align with the diamond’s cut, quality, and true beauty, as indicated on the certificate. If you’re not sure if the price of a lab-created diamond is too high, get an expert to take a look. It’ll help you make a solid decision before you pull out your wallet.

IGI lab-grown diamond certification
Alright, let’s talk about the International Gemological Institute (IGI). These guys have been in the game since 1975 and they’ve got offices all over the globe. They’re one of the big players when it comes to studying gemstones and lab-grown diamonds to figure out how legit they are.
After they’ve put a diamond through its paces, the IGI experts whip up a detailed report. Jewelry shops then display this IGI certificate alongside the lab-created diamond. It’s like a diamond’s passport, letting you verify its authenticity and make an informed decision. Plus, it keeps you from getting ripped off because you can see all the diamond’s features right there in black and white.
The criteria of IGI diamond
The IGI doesn’t mess around. They’ve got a team of qualified gemologists who use science to determine diamond quality based on specific grading standards. These gemstones are graded on the famous 4 C’s: carat, color, clarity, and cut.
Carat: This is all about weight. Generally, the bigger the diamond, the higher the price (assuming all other factors are equal).
Color: Diamonds are graded on a scale from D (colorless) to Z (light yellow or brown). They also check for fluorescence, which is how the diamond reacts under UV light.
Clarity: Using 10x magnification, experts look for tiny imperfections. The scale goes from “I” (Included) to “FL” (Flawless).
Cut: This is arguably the most important factor. It determines how light bounces around inside the diamond and back to your eyes. A well-cut diamond will have more sparkle and fire.
The grading reports of IGI
An IGI grading report is like a diamond’s resume. It includes:
A description of the diamond type
The cut and shape details
Measurements and proportions
Clarity and color grades

What exactly is an IGI Certificate for Lab-Grown Diamond?
An IGI certificate for a lab-grown diamond is like a birth certificate and a report card rolled into one. It tells you everything about how the diamond was created and what its qualities are. IGI does a thorough analysis of the environmental conditions used to create these diamonds, ensuring they’re similar to those mined from the earth.
Why is the IGI certification the best for lab-created diamonds?
IGI started out as the blue-collar workhorse of the diamond industry, but it’s gained a solid reputation for reliable grading standards. They’ve become the go-to for major jewelry chains in the US and Canada, including big names like Kay, Zales, James Allen, and Brilliant Earth.
Here’s why IGI is a favorite for lab-grown diamonds:
They’re fast and efficient
Their prices for certificates are reasonable
Their grading system is clear and comprehensive
They grade lab-created diamonds on the same 4 C’s as natural diamonds
While IGI might not be the top choice for natural diamonds (their grading can be a bit lax compared to GIA), they’re the current gold standard for lab-grown diamonds.
GIA lab-grown diamonds certification
Now, let’s discuss the industry leader in diamond grading – the Gemological Institute of America (GIA). They’re widely regarded as the gold standard in the gemstone world. A GIA certificate commands respect because of their reputation for consistency and strict grading practices.
For natural diamonds, GIA creates an extensive report covering everything from clarity and color to cut quality and carat weight. The good news? They’ve started doing the same for lab-created diamonds. The bad news? There aren’t many GIA-certified lab-grown diamonds out there yet.
Can lab-created diamonds receive GIA certification?
Yes, they can! But you’ll have to do some digging to find them. Most lab-created diamonds you’ll come across will have IGI certification. Why? Well, GIA reports are pricier, so most sellers stick with IGI to keep costs down. At the end of the day, IGI is currently the most reliable for grading lab-created diamonds, and paying for a GIA certificate will likely mean a higher price tag for you, the customer.
IGI vs GIA lab-grown diamonds price comparison
Let’s break it down with a real-world example. I compared Blue Nile lab-grown diamonds, both IGI and GIA certified. All the diamonds were E color, VS1 clarity, with excellent cut, polish, and symmetry. Here’s what I found:
| Diamond Grading | IGI | GIA | Price Gap |
|---|---|---|---|
| 1.00 Carat E VS1 Ideal Cut | $1,300 | $1,330 | 2.31% |
| 1.5 Carat E VS1 Ideal Cut | $2,520 | $2,550 | 1.19% |
| 2.00 Carat E VS1 Ideal Cut | $4,040 | $4,210 | 4.21% |
| 2.5 Carat E VS1 Ideal Cut | $6,080 | $6,310 | 3.78% |
| 3.00 Carat E VS1 Ideal Cut | $9,640 | $10,070 | 4.46% |
As you can see, the price difference is minimal – just about 4% in this case. So, while GIA might have a fancier reputation, it doesn’t necessarily mean a much higher price tag for lab-grown diamonds.
What is the importance of IGI Certification?
Listen, when you’re dropping your hard-earned cash on a diamond, you want to be sure you’re getting what you pay for. That’s where IGI certification comes in. It’s like a guarantee that your diamond is exactly what it claims to be.
Reputable jewelers will always provide certificates with their diamonds. My advice? Always check the report before you buy. It’s just not worth the risk to buy a non-certified diamond. After all, you wouldn’t buy a car without seeing its history report, right? Same goes for diamonds.
Conclusion - My Personal Experience
In my years as a diamond consultant, I’ve encountered a wide range of preferences when it comes to lab-grown diamond certifications. I’ve worked with clients who were adamant about purchasing only GIA-certified lab diamonds. While these diamonds can be harder to find, the search often proves worthwhile for those who value GIA’s reputation. For clients seeking GIA-certified lab diamonds, I often recommend Blue Nile for their extensive selection.
On the other hand, I’ve assisted clients who were particularly interested in knowing whether their diamond was grown using HPHT or CVD methods – information that GIA doesn’t include in their reports. For these detail-oriented buyers, IGI certification is typically the better choice. IGI provides information about the growth technology, which is beneficial for those specifically looking for HPHT or CVD diamonds.
Ultimately, the best certification depends on your personal priorities. Are you drawn to the prestige associated with GIA? Or do you prefer the detailed growth information that IGI provides? It’s important to remember that while certification is crucial, it’s not the only factor to consider. The perfect diamond is one that not only meets the right standards on paper but also captures your attention with its brilliance and fire when you see it in person.
Frequently Asked Questions
Is IGI authentic?
Yes, IGI (International Gemological Institute) is a legitimate and well-respected gemological laboratory. Established in 1975, IGI has become one of the leading authorities in diamond grading and certification, especially for lab-grown diamonds. Their certificates are widely recognized and accepted in the jewelry industry.
Is IGI or GIA better for lab grown diamonds?
It’s like comparing apples and oranges – both are great, but in different ways. IGI is more common for lab-grown diamonds and gives you more details about how the diamond was made. GIA is known for being super strict with their grading. Your choice depends on what you’re after – IGI for more growth details or GIA for potentially more consistent grading.
Do lab grown diamonds get a certificate?
Absolutely! Lab-grown diamonds can and should be certified, just like their natural cousins. Reputable sellers usually offer lab-grown diamonds with certificates from recognized labs like IGI, GIA, or AGS. These certificates are like a diamond’s report card, telling you all about its 4Cs (cut, color, clarity, and carat weight).
Do IGI diamonds hold value?
While all diamonds tend to lose some value after purchase (kind of like driving a new car off the lot), IGI-certified diamonds do hold their value pretty well. The certification adds credibility and assures you of the diamond’s quality. Just keep in mind that lab-grown diamonds generally depreciate more than natural ones because they’re getting cheaper to produce and there are more of them on the market.
Are GIA certified diamonds more expensive than IGI?
Generally speaking, GIA-certified diamonds (both natural and lab-grown) tend to be a smidge pricier than IGI-certified ones. We’re talking about a 0.5% to 4% difference, usually. This slight bump in price often comes from GIA’s stellar reputation and potentially stricter grading standards. But for lab-grown diamonds, the difference is usually pretty minimal.
What is the best certification for lab diamonds?
Right now, IGI is considered the go-to for lab-grown diamond certification. They give detailed reports and are widely accepted in the market. But GIA is also highly respected and gaining ground. The “best” certification really depends on what you’re after – IGI for more details about how the diamond was made, or GIA for potentially stricter grading standards. Both are solid choices for making sure you’re getting a quality lab-grown diamond.
