Vladimír Kondratěnko
Διευθυντής γραφείου Arete Diamond
Vladimír participated in most negotiations with international suppliers as part of the family jewelry business from a very young age — first as an observer and later as the company’s managing director.
At 18, he completed his first gemological course in London on diamond grading from GEM-A. He then traveled to Antwerp, Belgium, where he established a lasting friendship and business partnership with a prominent diamond dealer representing one of the world’s largest diamond cutting companies.
He continued his education at the leading European gemological laboratory HRD Antwerp, where he received the Certified Diamond Grader diploma.
A significant milestone in his career was the opening of the Arete Diamond office in the Stock Exchange Palace in Prague 1 in 2009. In 2011, he completed diamond grading studies at GIA and received the GIA Diamonds Graduate diploma.
In 2012, at just 22 years of age, he was officially invited by his business partners in Antwerp to become a member of the diamond exchange. Vladimír thus became the youngest member and shareholder of Diamant Club Van Antwerpen from the Czech Republic.
