Explaining Diamond Laboratories

When shopping for your diamond engagement ring you should always see the diamond’s grading report certified by a well known gemological laboratory. This is the only way of knowing exactly what you are paying for.

There are many types of grading reports and a vast variety of grading laboratories in the world. The best one and the only one that we recommend is the one that invented the international grading standards used by all laboratories around the world, the Gemological Institute of America (GIA).

GIA Diamonds Explained

The Gemological Institute of America (GIA) is the most respected laboratory in the diamond industry and for those of us involved in the industry, they are a reliable source of information.

Diamonds graded by this worldwide non-profit organisation, dedicated to producing consistent, accurate and unbiased grading reports, are the most highly valued in the industry.

The Prestige of the GIA Certification

A GIA diamond grading report details an appraisal of the 4Cs and is the result of work from a whole team of gemologists. Trained eyes scrutinise the diamond using specific tools and analyse the ratios of the dimensions, clarity, colour, polish, symmetry and other elements before determining its grade. Any diamond that weighs over 1.0 carat will be automatically assessed for clarity and rated on a plot chart of inclusions, and round diamonds also include a cut grade on their reports.

All of our diamonds have a unique serial number laser inscribed on the girdle which enables you to match the diamond to its certification.

GIA Certification For You

I always use GIA diamonds for any diamond engagement ring that we design and once I explain the reasons to my clients they understand why. Quality is guaranteed, as well as authenticity and honesty with regards to the special diamond they choose. So if you take one thing away from this article, remember GIA diamonds are the only way to go!
