The Amsterdam diamond cutter Moses Elias Coster moved into factory premises at Waterlooplein in 1840, and Coster Diamonds was born. During that time, diamonds were still cut by machines literally powered by horses. Today, they are located in three grand mansions, beautifully situated between the Rijksmuseum and the Van Gogh Museum. They sell loose & set diamonds as well as offer a Coster Diamond Certificate which will assure you of the authenticity and quality of your diamond.
