Diamond Certification

GIA diamond certificate

What is the Diamond Certification?

The certification of a Diamond is always an added value, like an identity card that lasts over time. Considering the importance of the classification of each diamond, it is always advisable that it has been scientifically checked and certified by a qualified gemological analysis laboratory.

For example, the Diamonds treated by Torrini, which in most cases have the certificate of the Gemological Institute of America (GIA), have always been free from any conditioning, therefore totally impartial. There are other credible gemological laboratories of the highest level, such as HRD in Antwerp.

Diamond Certification

The Diamond Certification collects all the characteristics of the stone. The main features reported are:

Depending on your budget, one can take into consideration the color of preference. 

  • The Diamond Color indicates the absence or presence of other chemical elements that could give the stone a series of yellow shades.

  • The Diamond Clarity is evaluated to classify a stone with its natural internal and external characteristics.

  • The Diamond Cut strongly influences the brightness of the gemstone.

  • The Diamond Carat is the unit of measurement for calculating the weight of Diamonds.

Diamond Grading Reports and Diamond Dossiers

Buying a diamond almost always requires a substantial economic investment. The certificate drives the need for the Diamond to be purchased to have its internal characteristics, often unique, very clear.

The two main certificates issued by the GIA are the “Diamond Grading Report” and the “Diamond Dossier” which, although similar, offer some distinctions. They are both very valid, reporting the existing laser writings on Diamond's belt.

Diamond Grading Report includes all the characteristics starting from the 4C's: cut, purity, color, and carat. It also shows the measurements and shape of the gem, the map of features, and additional parts.

Diamond Dossier offers the same information minus the track diagram and, therefore, the feature map.

Is it important to get a certificate when buying a diamond?

Even if this certification can have little impact on the price, the precise reading of a GIA-certified diamond is essential. It is the identity card of your Diamond with international value and recognition.

  • Confirm the qualities of your Diamond.

  • It helps to verify the identity of the Diamond in the event of a repair or for insurance

  • It is beneficial if you want to resell the Diamond

All Diamonds sold by Torrini usually have a GIA certificate.

Are all diamond labs equally important?

The GIA standards are internationally recognized and are a reference for almost all Gemological Laboratories in the world. Nevertheless, Torrini also grants its reliability to Antwerp's International Gemmological Institute (IGI) and Hoge Raad voor Diamont (HRD).
