LABORATORY

The GECI laboratory was launched with the aim of offering complete reliability and

professionalism in the field of identification and grading of diamonds, colored

gemstones and pearls.

The GECI laboratory is an independent and impartial entity and so are the evaluations

expressed in the Reports; evaluations made strictly in line with the global gemological

standards (International Diamond Grading System ®) and in compliance with

national and international regulations.

Every GECI Report, statement of the identity and quality of a gemstone, is written in

English and includes identification and safety codes, which make it unique and

impossible to imitate.

The GECI laboratory is equipped with the highest level of gemological instruments

managed and coordinated by a LIMS software (Laboratory Information Management

System), which enables the integrated management of multiple types of data and

processes. All the services offered by the GECI laboratory are aimed at both individuals

and businesses alike, always in full respect of privacy.
