A New Chapter: Royal Coster Diamonds Unveils Renovated Boutique

On November 20 and 21, 2023, Royal Coster Diamonds hosted two shopping nights to celebrate the renovated boutique. In the past weeks, extensive work has gone into the renovation of the store, giving it a contemporary look while preserving the authentic Amsterdam details. Additionally, a new entrance has been opened at Paulus Potterstraat 6. This new entrance makes it easier for targeted shoppers to step inside and immediately admire the jewels and diamonds. It's important to note that this entrance does not replace the one at Paulus Potterstraat 2, as it will remain accessible for everyone to explore the impressive cutting room alongside the goldsmiths. 

Guests were welcomed with a glass of champagne and then had the opportunity to view the renovated boutique. They could also explore the new Canals of Amsterdam Collection. The collection is inspired by the city of Amsterdam and is characterized by its asymmetrical design, radiating perfect imperfection.

You are more than welcome at Paulus Potterstraat 6, Amsterdam, to admire the sparkling jewels, diamonds, and the new Canals Of Amsterdam Collection.
