IGI Vs GIA: Which Lab Is The Best?


There are a lot of diamond certification labs out there.  And luckily, there are far fewer than 10 years ago. Until then, there was a bunch of labs that systematically over graded stones.  It was a big scandal when the story broke.  As a result, a lot of these labs went under.  EGL Israel, EGL International, and EGL USA all disappeared.  So did lot of others than were not big players.  But you could find stones they certified all over the internet, especially on places like Ebay.  In this post, we will discuss the two most common remaining diamond labs: IGI Vs GIA.  We will also discuss what to look for and avoid in a diamond certificate in general.

What Are Diamond Certification Labs – IGI Vs GIA

Diamond certification labs are independent organizations that evaluate and grade diamonds based on their quality and characteristics. These labs use standardized criteria to assess factors such as cut, color, clarity, and carat weight to determine the overall quality of a diamond. The most well-known certification labs include the Gemological Institute of America (GIA), the American Gem Society (AGS), and the International Gemological Institute (IGI).

Consumers can rely on diamond certification labs to provide an unbiased and professional assessment of a diamond’s quality. The certification process involves thorough examination by experienced gemologists using specialized equipment to accurately evaluate the diamond’s characteristics. By obtaining a certification from a reputable lab, buyers can have confidence in the quality and authenticity of the diamond they are purchasing.

Diamond certification labs play a crucial role in the diamond industry by providing an objective evaluation of a diamond’s quality. Whether buying or selling a diamond, having a certification from a reputable lab such as GIA or AGS can offer peace of mind and assurance of the diamond’s value and quality. It is recommended to always look for diamonds with certifications from recognized labs to ensure transparency and authenticity in the purchase.

What Happened in 2014?

In 2014, the EGL diamond certification scandal shook the diamond industry. EGL, the European Gemological Laboratory, was accused of issuing inflated grades on diamond certificates, leading consumers to overpay for lower quality stones. This scandal raised concerns about the credibility and consistency of diamond grading standards within the industry. Many consumers were left feeling deceived and uncertain about the true value of their diamonds.

The scandal prompted a significant backlash from both consumers and industry experts. It highlighted the importance of transparency and accuracy in diamond certification. As a result, many consumers became more cautious and started to seek out reputable laboratories with stringent grading standards. The EGL scandal served as a wake-up call for the diamond industry to prioritize integrity and honesty in diamond grading practices.

In the aftermath of the EGL diamond certification scandal, the industry saw a shift towards more reliable and consistent grading practices. Consumers became more informed and vigilant when purchasing diamonds, emphasizing the need for trustworthy certification. This event underscored the significance of reputable grading laboratories and the importance of ensuring that consumers receive accurate information about the quality and value of their diamonds.

What’s The Difference Between IGI Vs GIA Diamond Certifications?

When considering a diamond purchase, it’s essential to understand the difference between IGI vs GIA certifications. The International Gemological Institute (IGI) and the Gemological Institute of America (GIA) are two well-known diamond grading laboratories. Both organizations provide detailed reports on a diamond’s characteristics, including the 4Cs – cut, color, clarity, and carat weight. However, there are some distinctions between the two certifications that buyers should be aware of.

IGI is recognized for its consistency in grading diamonds and is often preferred for colored gemstones. On the other hand, GIA is highly regarded for its strict grading standards, particularly for color and clarity. Both certifications are reputable and widely accepted in the industry.  However, GIA is generally considered the benchmark for diamond grading due to its stringent evaluation criteria.

In conclusion, whether you choose an IGI vs GIA certified diamond ultimately depends on your preferences and budget. Both certifications offer valuable information about a diamond’s quality, helping you make an informed decision. It’s advisable to review the specific details of each certification and consult with a trusted jeweler to ensure you select a diamond that meets your criteria and expectations.


IGI Vs GIA:  Which Is Better?

When it comes to choosing between IGI vs GIA for diamond grading, it’s essential to consider their differences. The International Gemological Institute (IGI) is known for its efficient service and lower cost.  This makes it a popular choice among many consumers. On the other hand, the Gemological Institute of America (GIA) is highly respected for its strict grading standards and consistency in evaluations.

IGI is often preferred by those looking for a budget-friendly option without compromising too much on quality. They provide quick turnaround times, which people love.  They are also generally more affordable compared to GIA. However, some critics argue that IGI may be more lenient in their grading, potentially leading to overestimation of a diamond’s quality.

GIA, on the other hand, is recognized worldwide for its rigorous grading methods and strict adherence to standards. While their services may come at a higher price point, many consider the GIA certificate to be the gold standard in the industry. Choosing between IGI and GIA ultimately depends on your priorities.  Whether you value affordability and efficiency or stringent grading and reputation.  But know that both are reputable institutions providing reliable diamond grading.

IGI Vs GIA – Labs To Avoid

Looking for a reliable diamond certification lab is important. Avoiding uncertified or lesser-known labs that may not provide accurate assessments is crucial for this. Opt for labs that are accredited by reputable organizations such as GIA, IGI or the American Gem Society (AGS) to ensure credibility and quality assurance.

Avoid labs that lack transparency in their grading processes or refuse to disclose their testing methods. It’s crucial to choose a certification lab that follows strict guidelines and industry standards to guarantee the accuracy of the diamond grading report. Transparency is key in ensuring that you receive an unbiased evaluation of your diamond.

Steer clear of certification labs that offer suspiciously quick or overly generous grading results. Reliable labs take the time to thoroughly examine each diamond and provide detailed reports based on the 4Cs (cut, color, clarity, and carat weight). By avoiding hasty or inflated certifications, you can trust that the grading report accurately reflects the quality of your diamond.

Some of the labs we do not recommend are anything from EGL with a caveat.  EGL USA can sometimes be reliable.  But those are older certificates that you rarely see anymore.  GCAL, IGL, and AIG are just a few of the ones that we can think of.  Anything on Ebay that isn’t GIA or IGI will probably be a joke.

IGI Vs GIA – A Word On Appraisals

Diamond jewelry appraisals are often not reliable for determining the true value of the piece. Appraisals can vary widely depending on the appraiser’s expertise and biases. Factors such as market trends, demand, and the specific buyer can greatly influence the value of a diamond piece. Therefore, it’s important to consider multiple appraisals and do thorough research before selling or buying diamond jewelry.

Additionally, some appraisers may provide inflated values to benefit the seller or the appraiser themselves. This can lead to unrealistic expectations for the seller or paying more than necessary for the buyer. Seeking appraisals from reputable, independent appraisers can help ensure a more accurate valuation of diamond jewelry. It’s crucial to be cautious and skeptical of appraisals that seem too good to be true.

Diamond jewelry appraisals can provide a general idea of the value of a piece.  However, they should not be solely relied upon for determining the true value. It’s advisable to seek multiple appraisals from trustworthy professionals.  It is also good to consider other factors such as market conditions and personal preferences when assessing the worth of diamond jewelry.

In other words, do not rely on an appraisal for much.

Final Thoughts On IGI Vs GIA

When considering IGI vs GIA for gemstone certification, it’s important to weigh the pros and cons of each. The International Gemological Institute (IGI) is known for its efficient service and cost-effective pricing. On the other hand, the Gemological Institute of America (GIA) is highly regarded for its stringent grading standards and global recognition. It ultimately comes down to your priorities and budget when choosing between the two.

Both IGI and GIA have their own strengths and weaknesses. Whether you opt for IGI or GIA, ensure that the certification aligns with your expectations and requirements. By understanding the differences between the two, you can make an informed choice that best suits your gemstone certification needs.
