At Royal Coster Diamonds, we understand that the search for the perfect ring is a special journey. Since 1840, we have been welcoming lovers of beauty to our historic polishing factory in the heart of Amsterdam. With us, you step into a world where craftsmanship and passion come together in every unique design. 

A royal tradition since 1840

Our history exudes craftsmanship and royal allure. We proudly carry the designation 'Royal', a recognition of our many years of dedication to quality and integrity. Great names in history, including Empress Sissi and King Edward VII, have already found their way to our polishing shop. When you choose one of our rings, you carry a piece of this rich heritage with you. You are not simply investing in a piece of jewelry, but in a legendary work of art that effortlessly stands the test of time. 

The timeless splendor of gold rings with diamond

Gold and diamonds together form the most iconic combination in the art of jewellery. In our collection you will find various gold rings with diamonds, each with its own character. Whether you love the warm glow of yellow gold or the modern look of white gold, the stone is always the focus. Our experts manually select each diamond based on the strictest requirements for clarity and color. This way we guarantee that your ring will attract attention for a lifetime due to its unprecedented brilliance and refined finish. 

Our master polishers and their unique expertise

The secret behind the brilliance of our rings lies in the hands of our master polisher. These craftsmen master techniques that have been passed down from generation to generation in our Amsterdam polishing shop. They transform rough stones into beautiful jewels with a precision that you won't find anywhere else. In addition to the classic shapes, we also offer patented cuts that maximize light penetration for a spectacular effect. This technical superiority ensures that every stone in your ring comes into its own.

Capture your best memories forever

A ring is often much more than a decorative object on your finger. It marks the big milestones in your life, such as a proposal, an anniversary, or the birth of a child. With such a purchase, you create a tangible inheritance that you can later pass on to your children or grandchildren. It is a symbol of love and connection that reminds us of that special event every day. We are happy to help you find a piece of jewelry that perfectly reflects this emotional value. 

The sophistication of a gold diamond ring

Are you looking for a classic design that never goes out of style? A gold diamond ring from our collection offers that desired balance between luxury and wearability. Our designers pay a lot of attention to the setting, so that the diamond sits securely and at the same time catches as much light as possible. The result is a piece of jewelry that looks beautiful both on a festive occasion and in everyday life. You can feel the quality of the materials and craftsmanship as soon as you slide the ring on your finger.

Exclusive cuts for unprecedented brilliance

Innovation never stands still for us, even after almost two centuries of experience. Our patented cuts, such as the Royal 201, have more facets than the standard brilliant for extra fire. These unique techniques make our collection distinctive compared to regular jewellers. You choose a rarity that you can only find at the oldest diamond polishing factory in the world. The way the light dances in the stone proves the mastery of our craftsmen. 

Find the ideal diamond ring gold that suits you

When choosing the right diamond ring gold, personal taste and the shape of your hand play a major role. Our advisors take the time to compare the different styles and carat weights with you. Do you want a subtle solitaire ring or a distinct model with several stones in a pavé setting? The choice of the right gold color also enhances the natural brilliance of the chosen diamond. You only leave our polishing shop when you are sure that the ring perfectly matches your personality. 

A visit to our historic polishing factory in Amsterdam

Nothing beats the experience of admiring diamond rings in real life under the right lighting conditions. We cordially invite you to our monumental building on Museumplein for a personal consultation. While you enjoy the historic ambiance, our experts will tell you all about the 4 C's and the origin of our stones. You will have the chance to try on different models and see the craftsmanship up close. We make the purchase of your dream ring an unforgettable experience that sparkles as much as the diamond itself.
