Since Adiamor’s loose diamond inventory is primarily made up of GIA certified stones, in this post we’ll talk about the key differences and superior qualities that make GIA labs the most widely used and most trusted source of diamond certifications, but first let’s start with a summary of the advantages of purchasing a diamond certified by GIA.

The Main Advantages of buying a GIA Certified Diamond

  1. You know that the diamond you purchase is a natural diamond.
  2. You can easily compare stones due to the consistency of grading.
  3. You will know exactly what you are buying since every important attribute of the diamond is listed in the certificate.
  4. You will get what you pay for.

What is a Diamond Certification?

A diamond certification is a document  provided by the gemology lab to document the lab’s process of inspecting and grading the stone, and to serve as an official report on all identifying or otherwise notable features of an individual diamond. GIA certifications are available in varying levels of detail as diamond grading reports, diamond dossiers, and, most recently, diamond eReports.

To be certified by the GIA, a diamond must be unmounted and have a carat weight of at least 0.15.  To clarify GIA does not certify a ring just a diamond.  Some jewelers or jewelry stores may inaccurately tell you that a ring is certified.  It is possible that the ring has been inspected by a GIA graduate gemologist, but this does not make the ring or the center diamond certified by the GIA laboratory.

Why Choose GIA Certification?

The GIA is known worldwide as the most trusted, precise source for diamond certifications. GIA certification standards and quality grading ranges are the most rigorous of any of the major laboratories, and consequently carry the most added value and guarantee the highest diamond quality.  GIA achieves the highest level of consistency of any of the major laboratories in part by grading diamonds in a consistent environment in all offices including the same lighting, the same paint color on the walls, and the requirement for the graders to wear only certain colors when grading diamonds. As a non-profit organization, GIA maintains a standard of complete integrity and impartiality.

How Do I Know the Diamond and/or Certification is Genuine?

GIA certified diamonds are  laser inscribed with the unique report ID number to protect owners from fraud, and aid recovery in the event of a theft. This number matches the diamond to the report corresponding to its quality grade and identifying features.  Diamonds above 1 carat sometimes don’t have inscription since the inclusion pattern acts like a fingerprint to identify the diamond.

To prevent certificate forgeries and alterations, the GIA also places security features within the document itself including holograms, copy guards, and microprinting, the same features used to prevent fraud in financial institutions.

Thanks to these measures, you know what you are buying and what you will get.  Purchasing GIA certified diamonds online carries no additional risk compared to buying in a store due to the incredible consistency and the ability to validate you have the diamond you paid for.  Customers are assured of the diamond’s authenticity and the veracity of the associated report; consumers even have the option of verifying details directly with the GIA or with a third party gemologist.

Your Diamond’s Unique Features

Quality is determined and cataloged under the famous “Four Cs” of diamond grading: cut, color, clarity, and carat weight. Flaws in the diamond such as inclusions, clouding, pits, and poorly cut facets are noted in both the written report and in an illustration of the diamond showing the location and severity of each flaw.

The diamond’s weight is recorded using a state-of-the-art electronic micro-balance scale that provides an exact measurement to five decimal places, and color grade is determined in a standardized viewing environment. Your GIA certification will also evaluate qualities like the stone’s  polish and symmetry each of which are taken into account for the final overall quality assessment recorded in your diamond’s report.

GIA – The Worldwide Standard for Evaluating Diamond Quality

GIA established the “4Cs” in the 1940s which has become the worldwide standard for evaluating diamond quality.  So if you believe in using the 4Cs to evaluate and compare diamonds you already have some knowledge of and trust for the GIA Laboratory and its certification process.
