Often called the 5th C of diamond classification, certification is an important factor when buying online and even retail.

A diamond's value is based on objective characteristics like the 4Cs and the relationship of these characteristics determines the price of a diamond. A slight deviation may result in significant difference in the price of a diamond. And this is where certification may help you to make the correct choice and compare apples to apples. No diamond are alike but they come very close and having a certified diamond will help you objectively compare them.

The above is not the only reason to purchase a certified diamond. Without certification there is a good chance you may be buying a diamond that is a grade or more below the claimed grade. Without a reputable agency certificate you are relying on the sellers integrity that the diamond’s characteristics are accurate and not overstated. A number treatments enhance diamond's clarity and colour, such as removing a yellow tinge or fracture filling, laser treatment, HPHT treatment (high-pressure and high-temperature treatment) and a variety of other enhancement and not to mention the abundance of man-made or lab grown diamonds. In addition these type of treatments make diamonds fragile and brittle and prone to damage especially in engagement rings that usually get knocks.

So who can you trust to give you the correct information?

This is why certification by a reputable agency has become so important to help you make the correct decision. There are a number of reputable and well-known diamond grading labs in the world like:

Gemological Institute of America (GIA) American Gemological Society (AGS) European Gemological Laboratory (EGL) Diamond High Council (HRD, which is an abbreviation of the Dutch “Hoge Raad voor Diamant”)

When comparing and choosing diamonds, the reliability of their grades is only as good as the certifying lab’s reputation as a little shift of colour or clarity can mean a few hundreds if not thousands of dollars difference. We all have seen 0.50 carat diamond rings for $1000 and another one for $6000. How can this be? Simple answer is that one of them is a lemon.

Diamond grading, although based on strict and set standards, processes and procedures, has some subjective elements especially when determining colour. So stricter grading and consistency in grading is a characteristic most valued and we believe Gemological Institute of America (GIA) offers that consistency and is the most widely used and trusted name in the diamond trade.

We want to make sure that you as a consumer is well informed when comparing and making a decision and reputation is very important to us.
