The term "Certification of precious stones is a term that is used widely in the jewelry market in order to facilitate the communication between customers and merchants as an established way to secure their transactions.
In the jewelry market we can find more terms such Guarantee, Warranty etc that appear as small cards or booklets filled up with various specifications of each company's products.
However, these terms refer to each transaction's guarantee and in no way do they represent a certification of the certain features of a specific product, such as the gemologists' valid estimations and written reports according to the international gemologist law.
When we refer to a precious stone "certification" we actually refer to a written report that imprints an estimation a specific moment and impartially declares the quality features of a precious stone prior to a combination of scientific examination with the use of special gemologists' instruments and is issued exclusively from certified gemologists! Thus, the certification of a precious stone is important and of decisive importance for the further commercial course of a precious stone (resale, insurance etc.).
It is worth mentioning that a certification never includes the value of a specific stone (because that is the merchant's job) but it only contains the authenticity and unique features (for example the diamond has the 4 C's).
