Royal Coster Diamonds Contributes at the Prinses Máxima Center Charity Lustrum Gala

Prinses Máxima Center Charity Lustrum Gala

On the 28th of September, 2023, the Prinses Máxima Center Charity Lustrum Gala took place at the Beurs van Berlage in Amsterdam. Royal Coster Diamonds offered an item for auction that raised an impressive amount of €11,200. During this special evening, a total of €4,523,645 was raised. This collected amount will be used for projects related to talent development and immunotherapy.

The highlight of the auction was a 0.70-carat diamond, cut in the exclusive Royal 201 shape by the Master Diamond Cutters of Royal Coster Diamonds. The auction lot included a choice of setting and a unique Royal Experience tour. The lot has already been claimed by the highest bidder.

The Princess Maxima Center is committed to pediatric oncology with the mission: to cure every child with cancer, with optimal quality of life. During this beautiful evening, with the presence of Her Majesty Queen Máxima and 550 other invited guests, there was reflection on the past five years and the urgency of this mission.
