In 1980, Athina and Vasilis Makrygiannis launch PETRADI, a jewelry store dedicated to fine gold jewelry with precious stones, which quickly becomes a point of reference for high quality jewelry.
In 1999, Vasilis Makrygiannis becomes one of the few graduates of GIA in Greece, earning the title of Graduate Gemologist (G.G.). He establishes a gem laboratory where every diamond and precious stone is carefully examined and verified.
PETRADI features a fully equipped gemological laboratory where precise evaluations of precious stones are conducted. It is also the only jewelry store in Greece with three certified gemologists – diamond experts, ensuring specialized knowledge and reliability.
With expertise, transparency, and professionalism, we guide you toward making a well-informed and confident choice.
Choosing a diamond is a unique process that can sometimes feel complex. Understanding our customers' concerns, we dedicate the necessary time to clearly explain the key evaluation parameters.
Additionally, every solitaire ring is accompanied with a certificate of authenticity from our jewelry store, as well as an independent certification from one of the three leading gem certification institutes (GIA, HRD, IGI). This guarantees the highest level of assurance regarding the characteristics of each diamond.
