How important is the certification date for GIA diamonds?

GIA – the Geological Institute of America - is an institute that is the leading authority on all kinds of gemstones including diamonds, coloured stones and pearls. At La Vivion, we have a brilliant collection of GIA diamonds that have been graded to meet their standards. But how important is the certification date for diamonds approved by the GIA?


What Is A GIA Certificate?


The GIA produce diamond grading certificates when the diamond is submitted for GIA certification. This is done by the cutter of the diamond or the dealer. The diamonds submitted include no company information, such as, names or logos. This is so that GIA personnel remain impartial as they cannot identify the owner of the diamond during the grading process.


These certificates have important information of the diamond sent in for certification, such as, weight, dimensions, colour, clarity grades and key proportions. There is a unique identifying number, and the date that the diamond was certified, presented on the certificate. Each diamond that is submitted also receives a diamond dossier certificate this is inscribed onto the diamond with a laser, as well as, a GIA certificate number.


Is It Better To Buy GIA Diamonds With A Newer Certification Date?


The date on the certificate is simply to say when the diamond was certified. However, many buyers will use this date to determine how ‘old’ the diamond is. This is obviously not the actual age of the diamond, as all diamonds are beyond ancient, but an ‘old’ diamond is classed as how long ago it was cut.  Some buyers prefer diamonds they see as ‘fresh’, in that they were recently cut or not ‘used’.


This means that they prefer not to sell diamonds that have been previously owned. The fact that the diamond is second hand does not affect the diamonds quality but it does affect the purity and value for the new owner.


Although most buyers use the certification date of GIA diamonds to purchase a diamond that was recently cut, the certification date is no assurance that the diamond has not been cut a long time ago. This is as diamonds that have been certified a long time ago will be issued with a new certificate.


This is also true if the diamond is sold back on the market. When the new certificate is issued, the old one is thrown away. The date on the certificate is when the diamond was last certified by the GIA; it will not indicate how long it has been since the diamond was cut.


Therefore, most of the time when someone claims the diamond was freshly cut they have either cut the diamond themselves or are simply speculating.


The certification date is important as you will know the diamond is GIA certified but it is otherwise unimportant as it will not tell you when the diamond was cut or if it has been previously owned but simply when the diamond was GIA certified. The history of the diamond is not as significant as other information given on the certificate about the diamond, such as, its colour and clarity grades.
