Explanation of Certification

Shopping for the perfect diamond can be confusing in a world full of options, especially if you’re not an expert. However, many reputable jewelers across North America and Europe offer GIA and EGL USA certified diamonds, which ensures quality and helps minimize the budding options. The reports on quality from independent laboratories help take the speculation out of diamond shopping and give consumers clarity when it comes to making a purchase.

The Function of GIA & EGL USA

Organizations like GIA and EGL USA are the recipients of diamonds from jewelers. They inspect and report on the detailing and quality of the diamonds they receive, which will determine the value of the diamond. EGL and GIA reports rate diamonds on various characteristics relating to the well-known 4 c's of diamond value (clarity, color, carat, cut). Receiving certification from institutions such as these, that are widely respected, have become preferred over private appraisals. This could also have to do with the fact that appraisers are not required to use standardized methods or have any training.

GIA

The Gemological Institute of America (GIA) was founded in 1931 in an effort to imply standardized evaluations on diamonds and has now reached acclaim as one of the most advanced labs in the world. This organization now certifies more diamonds than any other in America. Most individuals seeking reports from GIA are jewelers, however GIA is open to anyone sending their loose diamonds to be examined by their labs.

EGL USA

EGL USA was founded in 1977 and became independently owned and operated in 1986. It is not affiliated with any EGL derived laboratories outside of North America. EGL USA also does not facilitate or support the standards by which those institutions grade their diamonds. EGL-named labs outside of North America are banned from using the EGL trademarks in the United States. This has to do with their different metric of measuring value or worth of diamonds in comparison to other institutions that follow the same trade. No service or information on such foreign reports can be given by EGL USA. Customers are strongly advised to recertify the stones and/or jewelry with foreign reports, in the United States, to guarantee that necessary rules and regulations are respected. The lab does not accept loose blood diamonds. Also, the lab strongly recommends that customers be cautious about stones they are uncertain about the origin of. Any analysis will result in a charge. EGL USA has facilitated front-line gemological research, testing, and laboratory analysis for over three decades now. This ongoing scientific effort exemplifies the organization’s fundamental commitment to safeguarding the industry and the consumers in it.

IGI (sometimes used)

The International Gem Institute (IGI) was founded in 1975 and is the oldest of its kind and one of the leading gem labs worldwide. Similarly to GIA and EGL USA, the IGI Diamond Report is one that verifies to the authenticity of a stone. Each diamond is held under high scrutiny for purposes of identification in terms of synthetics, simulants and possible treatments made to the gemstone. IGI issues over one million reports per year and its reputation as a front-runner in the industry is unmatched.

Benefits

Because most diamond buyers are not qualified as experts in evaluating stones, it difficult to know whether or not you're getting a good deal. Certifications and quality reports from distinguished institutions like GIA and EGL USA allow buyers to have the quality of the diamonds ensured and compare prices of diamonds of similar size and quality. This is helps with finding the right deals on a diamond.

Warning

Certifications from GIA or EGL USA institutions does not indefinitely rule out the stone to be a conflict diamond (defined as a diamond that originates from an area controlled by forces opposed to legitimate and recognized governments), although there are other ways to avoid this. Additionally, it should be considered that when making the decision to buy certified diamonds, full understanding of what is on the diamond quality report is necessary to make an informed decision on going through the process.
