Your Complete Guide to Diamond Certification

So, you’ve bought yourself a solitaire diamond pendant with your hard-earned money! Congrats! Now comes the big question: Did you get your diamond certification? If yes, then well and good. If not, then that diamond you bought is nothing more than just a mere shiny rock.

Surprised? Yes, that is how important a diamond certification is. In this article, experts from Khwaahish, the best diamond jewellers in Chennai, elaborate on the importance and other important aspects of diamond certification.

What is a Diamond Certification & Who Issues it?

Issued by the Gemological Institute of America (GIA), a “Diamond Certificate” is a grading report that measures and evaluates the quality of a diamond based on the 4 Cs: Cut, Carat, Clarity, and Colour.

This grading report significantly influences the diamond’s final selling price. Only when a diamond is evaluated and graded by a reputed grading agency does it gain the value to be sold by diamond jewellers worldwide.

Who issues the diamond certification?

As we’ve already mentioned, GIA is one of the top agencies that grades and issues diamond certifications. Apart from GIA, there are several other agencies whose certifications also carry immense value. These agencies follow strict rules and regulations to evaluate, grade and certify each diamond that comes under scrutiny.

Some certifications to keep an eye out for include:

  • American Gem Society (AGS)

AGS was founded in 1934 and grades its diamonds on a scale of 0-10, with zero as the lowest and 10 as the highest. This society has over 3000 diamond jewellers, retailers and suppliers as its members and is considered the most reliable diamond certification source in the world. Each diamond certified by AGS undergoes a stringent evaluation process and is scrutinised by at least four gemology experts.

  • European Gemologocial Labs (EGL)

The EGL grades diamonds based on the 4 Cs and other aspects like finish, fluorescence, proportions and plotting. The EGL is considered to have looser grading standards.

  • International Gemological Institute (IGI)

With 18 labs across the world, the IGI has been grading diamonds since 1975. The lab not only grades loose diamonds but also evaluates diamond jewellery and has been grading “lab-grown” diamonds since 2005. IGI enjoys a high reputation amongst diamond jewellers in India.

  • Hoge Raad Voor Diamant (HRD)

The HRD is located in Antwerp, Belgium, a place that is synonymous with diamonds. This company uses a double coding system to evaluate natural, lab-grown and treated diamonds.

  • Diamond and Gem Laboratories of America (DGLA)

Started way back in1898 as D.Atlas & Co, the DGLA started appraising diamonds and diamond-studded jewellery in Philadelphia, USA. A DGLA certificate holds value amongst diamond jewellers but is considered next to or far lower than a GIA certificate.


What a Diamond Certificate Entails: A Diamond Jeweller’s Explanation

Khwaahish Diamond Jewellery, one of the best diamond jewellers in Chennai, states that most diamond certifications come with the following details:

  1. Date of gradation
  2. The grading agency’s report number
  3. Shape and cutting style
  4. Carat weight
  5. Cut grade
  6. Clarity grade
  7. Colour grade
  8. Symmetry
  9. Fluorescence
  10. Polish grade
  11. Girdle thickness
  12. Laser inscriptions
  13. Security features (If any)
  14. Culet size
  15. Depth
  16. Table
  17. General comments

The certificate will also have a picture of the diamond in profile view with all the proportions and characteristics in clear detail.

Some of the best diamond jewellers in Chennai state that grading agencies have different ways to evaluate and grade diamonds. For example, GIA and IGI will follow their standards while grading diamonds. The reliability of cut, colour, and clarity grades are only as good as the lab’s reputation. It is, therefore, important to look for consistency rather than the strictness of grading.

It is also important to note that all grading is subjective. For example, if IGI names a specific colour grade as “G”, AGS may name the same colour grade as “H”. As long as they maintain the consistency for this grade, both “G” and “H” are perfectly acceptable.

Price & Certification: What holds more value?

A diamond’s price should be heavily evaluated regardless of the certificate you receive. It is important that the price reflects the actual quality, beauty, and cut of the diamond. Both the certificate and the naked eye should reflect this information. Unless you are an expert, you can never be too sure about the price and value of the diamonds you purchase. Hence, it is best to approach famous diamond jewellers in Chennai renowned for their reputation and reliability.

Which is the best diamond certification?

Best diamond jewellers in chennai and across the world unanimously agree that GIA and AGS certifications carry a tad more value than others. If your diamond carries either of these certifications, you can rest assured that you have invested well.

That said, it does not mean that other certifications are not as valuable. Every diamond certification lab has its quirks for grading the 4Cs. These companies use an extensive database of information to optimise their results. The best way to avoid buying a diamond worth much less than appears on the certificate is to find out which labs are trustworthy and consistent.


Diamond Certification Benefits Stated by the Best Diamond Jewellers

A diamond certification is a premier credential of the stone’s authenticity and quality. It adds a very important consumer-protection element to how diamonds are bought and sold.

Above all, diamond certifications instil confidence in buyers because they are an impartial and honest evaluation of the stone’s quality, origin, and authenticity.

What is the Cost of Diamond Certification?

The price of a diamond certification like the one given by GIA is based on three factors:

  • Carat weight
  • Type of stone
  • Service Requested

The fee increases with the weight of the stone and the other services carried out by the specific lab.
