On December 20, 2023, the diamond house Royal Coster Diamonds officially reopened its enduring presence in the industry. Dating back more than 120 years, their buildings have undergone a radical makeover. The new, innovative experience now has a direct entrance via a third of its four historical buildings in Paulus Potterstraat 6 - the former Coster Watches.
During the renovation, Royal Coster Diamonds has carefully preserved the building's original stained-glass decorations from the early 1920s, which now enhance the rich heritage of their new showroom. Be among the first to enjoy the beauty of craftsmanship and discover the Royal Coster legacy in their new showroom.
While the original entrance (Paulus Potterstraat 2) will continue to be utilised for larger groups of first-time visitors, the new store will focus on accompanying private visitors to one of fourteen showrooms with greater discretion.
The secluded entrance will allow easier access for focused shoppers, on appointments or walk-ins, for any type of tailored advice. Simply walk in or make an appointment with one of the Sales Advisors at Royal Coster. You can also request a private consultation in your native language because they offer services in more than 25 languages.
With the launching of their showroom in Paulus Potterstraat 6, the oldest diamond house in the world proudly presents their new collection: Canals of Amsterdam. In honour of the country’s most famous UNESCO world heritage sites, the new collection from Royal Coster Diamonds is inspired by Amsterdam’s seventeenth-century waterways: a reflection of contrasts, within the ancient borders of the city of diamonds. The items in this collection are named after three of the city’s most prominent waterways: de Singel, de Spiegel and of course, de Amstel.
With baguette- and brilliant-cut diamonds, the craftsmanship displays refined asymmetrical compositions, available both in white and in yellow 18K gold. All of the jewellery pieces in this collection begin at 990 euros.
Characterised by smaller carat weights, in different combinations, Royal Coster Diamonds combines all of these elements to create sharp but playful contrasts. For example, with a Spiegel Bangle or an Amstel Ring, any outfit will immediately acquire a contemporary twist of youthful elegance. The contrasts can be enhanced even further because most items are stackable, meaning that at any moment, you can add your own flair or revive your set.
