Uniglo sells certified diamonds that conform to the respective diamond grading parameters. A diamond certificate intricately outlines the diamond’s unique characteristics, such as its cut, carat weight, color, and clarity. Also, the diamond certificate may include details pertaining to the diamond’s finish, which refers to its polish, symmetry, and fluorescence.

The most widely recognized and highly acclaimed diamond grading laboratories are the Gemological Institute of America (GIA) and the European Gemological Laboratory (E.G.L.). A Diamond Certificate from one of these labs or a lab of similar repute reassures you of its quality.

These labs grade your diamonds in an unbiased manner, based on certain parameters. Not to mention that a Diamond Certificate serves as proof of your diamond’s value. Therefore, it serves as a useful document for future valuation and also for insurance purposes.

As a matter of fact, we make it a point to sell conflict-free diamonds. Hence, we can provide you with a Kimberley Process certificate for each diamond you purchase from us.

We Offer GIA, IGI and HRD Diamond Certificates

While purchasing a certified diamond from Uniglo, you will receive the original diamond grading certificate. This document provides insights into your diamond’s unique 4Cs. Also, this diamond certificate confirms that the described gem is indeed what you have legitimately purchased.

However, a grading certificate is different from an appraisal or valuation certificate. The appraisal certificate tends to be lesser comprehensive and focuses on the monetary value of the stone. This value is derived based on estimations of the supply and demand of diamonds, global economic trends and other factors that influence it.

GIA Certification

Established in 1931, GIA is the most trusted laboratory, when it comes to grading diamonds, colored stones, and pearls. It is a non-profit organization, and the most trusted source of knowledge, standards, and education in gems and jewelry.

A certificate from IGI represents the all-important 5th C that no one should be without, ‘Confidence’. As a matter of fact, IGI is a standard of excellence, trusted worldwide by professionals and consumers. It is the world’s largest independent gem certification and appraisal institute for diamonds, colored gemstones, and jewelry.

When purchasing an HRD Antwerp graded diamond you can rest assured the characteristics described in its accompanying grading report have been thoroughly checked by expert gemmologists.
