Which Came First: GSI Diamond Certification or GIA Diamond Certification?
The GSI and GIA are both gemological laboratories that specialize in diamond certification. The GSI is a relatively new lab, having formed in 2005, while the GIA was founded in 1931.
The GSI has its headquarters in New York City and has branches in 13 different locations around the world, including India, Dubai, Israel, Belgium, Hong Kong, and Botswana. They use software and gemologists to assess diamond grading, always looking for innovative and efficient ways to improve their processes.
On the other hand, the GIA created the 4cs grading system in 1941, which is now the industry standard for measuring diamond quality. They are also known for their research and discovery in the diamond and gemstone field. They have gemological laboratories all over the world, including Taiwan, China, United Kingdom, India, and Japan.
Overall, while the GIA has been around longer and is widely recognized as the leading authority in diamond certification, the GSI is also gaining recognition as a significant player in the industry due to its focus on innovation and efficiency.
GSI Versus GIA Reports: A Comparison
Both GSI and GIA offer diamond certification reports for natural and lab-grown diamonds, colored gemstones, and fancy colored diamonds. However, there are differences in the types of reports offered by each grading authority.
The GSI offers several types of reports for diamonds and colored gemstones. The Comprehensive Diamond Examination Report is the most detailed report, which includes information on diamond shape, carat weight, color grade, clarity grade, cut grade, fluorescence, polish/symmetry, measurements, and a plotting diagram.
The Intermediate and Special Diamond Examination Reports offer similar information, but in a more compact form. The Modified Diamond Examination Report provides a brief description of the diamond’s characteristics.
Similarly, the GIA offers various types of reports depending on the type of diamond or gemstone being graded. The standard GIA Diamond Grading Report is used for natural loose diamonds over 0.15 carats, and includes information on diamond cut grade, color grade, clarity grade, diamond weight, graphic of diamond proportions, and plotted diagram.
The Natural Diamond Origin Report includes the same information as the GIA Diamond Grading Report, as well as confirmation of geographical origin and a laser inscription of the report number. The GIA Diamond Dossier Report includes all the same information as the GIA Diamond Grading Report, but also includes a laser inscription.
Overall, both GSI and GIA provide comprehensive reports on diamond quality and characteristics. However, the GSI offers more variations of reports, and its reports are often more detailed than those of the GIA. The GIA, on the other hand, is widely recognized as the leading authority in diamond certification and is often the preferred choice for many in the industry.
Comparing GSI and GIA Diamond Certifications: Pros and Cons
Now that we know what information both diamond grading authorities provide in their reports, let’s compare them based on their pros and cons.
GIA Diamond Certifications
- Widely considered the best in the diamond industry
- Ideal for resale or trade-up purposes
- Offers information on diamond origin
- GIA graded diamonds can be more expensive
- Harder to find at chain retailers such as Kay Jewelers or Zales
GSI Diamond Certifications
- More affordable than GIA certified diamonds
- Easier to find at chain retailers such as Kay Jewelers or Zales
- Harder to resell due to lower recognition
- Diamond grading standards may be perceived as looser than GIA’s
Here’s my expert opinion if you’re having trouble choosing between a GSI grading report and a GIA grading report:
When shopping for a diamond engagement ring online, I always recommend going for a GIA report over any other. Although GSI reports are also good, they are less commonly found online. If you’re looking for GIA certified diamonds of natural origin, James Allen is a great choice, while for lab-grown diamonds, I would suggest checking out Brilliant Earth’s GIA certified diamonds.
However, GIA lab diamonds can be harder to come by, so you could consider IGI or GCAL certificates instead.
You may encounter GSI reports at chain retailers, as they were originally created to cater to retailers. GSI uses grading software to grade their diamonds, which allows them to grade diamonds faster and in greater volume.
They also customize the diamond report to match the retailer’s needs, and sell them at a bulk pricing. However, I generally recommend avoiding GSI reports because they have looser diamond grading standards and are not designed with the individual buyer in mind.
Having said that, I don’t recommend buying GIA certified diamonds from chain retailers like Kay or Zales. Their GIA certified diamonds are usually priced higher than those found online with the same grade. James Allen, which is also under the same umbrella company, is an exception as they don’t price their diamonds the same way.
