Step into the world of Royal Coster Diamonds and explore the rich heritage of Amsterdam’s diamond tradition. Since 1840, we have crafted diamonds for royalty and celebrities. Now, it is your turn to witness the craftsmanship up close.
During your visit, you will be guided the art of diamond valuation using the 4 C’s: Cut, Color, Clarity and Carat. Watch as our master polishers and goldsmiths transform rough stones into sparkling masterpieces, a craft passed down through generations.
Admire the Royal 201, our signature cut and the most sparkling round cut natural diamond in the world, exclusively available at Royal Coster Diamonds. Marvel at the replica of the legendary Koh-i-Noor, repolished by our craftsmen for Queen Victoria.
From the factory floor you walk straight into a special exhibition where Diamond Museum Amsterdam presents the highlights of its collection while the museum prepares for its new home. The journey begins three billion years ago, two hundred kilometres below the earth, and ends in the ring on your finger. You follow Amsterdam's rise as the City of Diamonds, the cleavers and polishers whose hands shaped the gems of empires, and the four centuries of history that turned this city into the heart of the trade.
