Certifications

GIA Certification

(GIA – the Gemological Institute of America)
GIA is a non-profit organization that develops and implements quality assurance standards for diamonds and is considered the most prestigious gemological laboratory in the world.
GIA laboratories are located in key cities for the diamond industry: New York (the United States), Carlsbad (the United States), Johannesburg (South Africa), Gaborone (Botswana), Tokyo (Japan), Mumbai (India), Hong Kong (Hong Kong SAR of China), Ramatgan (Israel), Bangkok (Thailand)
GIA laboratories certify both diamonds and other precious stones.
In the course of the evaluation of each diamond, GIA experts receive precise geometrical parameters of the stone, assess the quality of the cut and the polishing as well as its color and clarity and the presence of fluorescence.
To date, almost all the GIA-certified diamonds contain a laser-engraved GIA logo and the number of the diamond on the girdle (the lateral side that separates the upper and the lower parts of the diamond).
The certificate also indicates whether a diamond has been subjected to any impact to improve its characteristics.
Artificially grown diamonds contain a separate mark in the certificate; in addition, the word “CREATED” is engraved on the girdle.
The database of certificates is available in the public domain on the GIA website.
Laser engraving in conjunction with geometric parameters and location of inclusions that are unique to each diamond is a 100-pct guarantee of protection against forgery.
The certificate itself also has several degrees of protection.

IGI Certification (IGI – the International Gemological Institute)

This institute is a laboratory founded in 1975.
Expert evaluation that is based on this standard is loyal to the color and the clarity of evaluated diamonds. Also, it can be fit to match the market demand.

HRD Certification (HRD – the High Diamond Council)

This organization is located in Antwerp (Belgium). This type of certification is characterized by a separate assessment of the proportions of a diamond such as the height of its crown and depth of its pavilion.

EGL Certification (EGL – the European Gemological Laboratory)

This type of certification places a particular emphasis on the control of the color and the purity of a diamond. The quality of the cut is not a priority area of this certification. An increased evaluation is possible in some respects due to particular features of the quality control system used in Europe.
Evaluations according to the EGL procedure also exist in the United States and in Asia (EGL USA and EGL Asia). Their evaluation is generally similar to the evaluation of the European organization but includes certain features specific to the region.
