The 4 c's of Diamonds - Part 5 of 5 - GIA laboratory graded diamonds

Why GIA certification is so important

Knowledge, integrity, and excellence are the words included in the GIA lab’s crest. GIA (Gemological Institute of America) was founded by American jeweller Robert M. Shipley in 1931, and is credited for inventing the international diamond grading system in 1953; famously the 4Cs that stand for Colour, Clarity, Cut, and Carat. It is highly esteemed among diamond experts on a global scale for the honesty and accuracy in diamond quality evaluation. Gemologists in this independent institution are constantly pioneering scientific methods of optimizing the process of grading diamonds. They analyze the vast majority of available diamonds across the world.


For honest retailers, the GIA reports and certificates are a precious tool and a form of validation. They set the universal standards of calculating a diamond’s value. The first such report was issued in 1955. Today, both fine jewellery professionals and clients can have access to such reports. Buyers of diamonds are entitled to these documents before investing in them, and sellers can definitely receive the outmost appreciation for showing their potential customers a GIA report for each diamond they are selling. GIA is also grading coloured diamonds, pearls, and a wide array of treated gems. They are the first and most credible source for detecting treated and synthetic diamonds with the help of advanced technological equipment.


GIA Principles

Each diamond is treated equally. Diamonds are passed on to the graders in the lab with client anonymity so that the evaluation is impartial, and not affected by any brand name considerations. GIA as a not-for-profit organization can be totally objective, acting without any vested interest, clearly as a third party in the whole process. They do not buy, sell, or supply diamonds within the industry. Each of their reports gives the results of an accurate scientific investigation described in a very comprehensive way. It’s the map of the diamond you are buying. Jewellers worldwide are proudly presenting the GIA report as a badge of trust and credibility that helps their customers end up with an educated decision and choice. In other words, this tool allows sellers to educate their clients around their options. Precise gem assessment is the key to clients’ protection from increasing fraud possibility within a highly competitive retail environment. We need to make sure that what you see is what you get, not what is marketed to you; and we know that GIA is the ultimate guarantee. This is the way to a smart gem purchase. In that respect, we are proud to share that all the engagement rings from RING jewellers come with a GIA certificate.


What about other Diamond grading laboratories?

GIA is the authority that established the 4Cs as criteria of precise diamond evaluation, and with them it established the need for certification. Each gem is assigned a GIA report number that is permanently stored in GIA’s database. Some jewellers provide you with alternative reporting that might inflate the quality of their gems as a means to greater profitability. Assessments about weight and cut are usually objective, yet those regarding clarity and colour can be diluted. In these two areas, differences are slight from one grade to the next and can be most clearly seen via microscopic analysis. Lighting and positioning can easily affect the client’s perception of the stone. Whenever you are offered a better price without a GIA report, think twice before getting convinced that it is actually a better deal and a value-for-money purchase. We want to make you feel comfortable about your choice and that’s why we stick to GIA certification. Here at RING jewellers we advise you to choose smart in all special moments of your life and we guide you through a great investment.
