World war II
The Nasielski’s found refuge in the Brazilian town of Rio de Janeiro where, despite the difficulties of the war in Europe, Julio managed to set up a Diamond Polishing factory and export his production to New York, USA.
After the war
The Belgian minister Van Zeeland convinced some Diamond producers to return to Belgium. Julio came back to Antwerp to help rebuild the Antwerp Diamond Corporation, and continued his polishing business.
In 1958 his son Henri S. Nasielski entered the business. He based himself on the family values to perpetuate the company, producing also larger size goods, selling original parcels to Antwerp dealers and pre-sorted parcels to foreign Diamond dealers traveling to Antwerp to buy Diamonds.
In 1990 his great-great-grandson Michel joined him and together they have brought this business into the 21st century. The production has been modernized, new technologies are used, globalization is a reality and the company has adapted to it.
Above his daily dedication to Nasielski Diamonds, Michel is also board member of the Antwerp Diamond Bourse since 2015 and active in various committees, and a board member of the Antwerp World Diamond Center since 2018.
Today Nasielski Diamonds deliver the right goods at the right price to their customers worldwide, in a record-breaking time, maintaining the same family values for more than 150 years: Honesty, Trust, Service, Efficiency.
