While buying diamonds, it is important to consider more than just the shine. It is important to understand the diamond quality and the value you’re investing in it. Certified gemstones ensure that you get value for money. Diamond jewelry can be tricky to buy with various look-alike gemstones and fake diamonds in the market. A SGL Certificate ensures that all the diamonds in your diamond jewelry, may it be in a pendant, ring, earring, bracelet or necklace, are authentic.
Solitaire Gemmological Laboratories or SGL diamond certification is recognized worldwide in certifying gemstones based on various parameters that we will discuss in detail here.
Why Is It Important to Buy Certified Diamond Jewelry
Imagine you are getting married, and you are overwhelmed with various choices. When you finally pick one, it does look like a Lab Grown Diamond, but it is not backed by any proof. You are just verbally assured that the diamond quality is good. You later find out that the clarity is not as good, or the color on the color grading scale does not justify the price.
Therefore, it is important to buy diamond jewelry with an SGL Certificate or an IGI Certification. These institutes are independent gemological institutes with experienced gemologists. SGL Certified Jewelry undergoes rigorous product testing and evaluation with special equipment for grading and evaluation of diamond quality. You can make an informed purchase and gain confidence with these certifications that grade diamond quality. Having SGL Certified Jewelry also helps in exchange and resale of your diamond jewelry to get the best value out of the diamond while focusing on diamond quality.
How To Read Your SGL Certificate?

1. Check Your Report Number

This is the most crucial element of your report as it helps you access your report digitally and cross verify the certificate’s authenticity with the issuing body of SGL certification. Every SGL report has a unique report number. Keeping a record of this ensures that you can access it digitally even in case you lose your SGL certificate.
2. Grading Information: Measurements you need to look for
This is a key element in the SGL report as it helps confirm if the actual size of the diamond is the one that was promised to you by your jeweler. This is a significant reason why it is important to buy from jewelers that only sell SGL Certified Jewelry.

a. Grading Information: Cut
The diamond shape in the report tells you how the diamond cut is. While a diamond shape is a personal preference, how it is cut determines diamond quality in terms of how it reflects light and shines. Apart from the shape of the diamond, the SGL certificate also highlights how brilliant the diamond reflects light by grading how well is the diamond cut. Grades typically include excellent, very good, good, fair, and poor. Prioritize this information mentioned in your SGL certification as it is one of the primary parameters that determine your diamond quality. This section in the report of SGL certified jewelry includes the polish, symmetry and the proportions which is also touched on in the technical portion of the SGL Certificate.
b. Grading Information: Color
Certified gemstones are available in various colors. The diamond quality of a colorless diamond is much more than a colored diamond. The diamonds are graded on the scale designed by the GIA. The colors range from D to Z, with D being colorless and Z being light yellow.
c. Grading Information: Carat
Diamond carat actually refers to the weight of the diamond. A higher carat usually means a bigger diamond but it doesn’t always mean better. For instance, two diamonds can have the same carat but vary significantly in diamond quality and price depending on cut and clarity.
d. Grading Information: Clarity
The SGL certificate is especially important to know the clarity of the diamond. It helps you understand the diamond quality by assessing any flaws and inclusions in the diamond which will heavily impact the shine of your diamond. A VS or SI clarity indicated in your SGL report is often the sweet spot for balancing quality and value.
Conclusion
These are the key elements included in the SGL certification. Another detail provided in the SGL report is the origin of your diamond. Whether your diamond is natural or lab grown, the diamond is real. However, the prices vary significantly and you cannot ascertain the origin of your diamonds without special equipment. Therefore, it is crucial to always ask for SGL or IGI certification while buying diamond jewelry. Record your unique report number for easy access or store a photo of your SGL certificate for easy access in the future.
