Coster Diamonds is one of the oldest still operating diamond polishing factories in Amsterdam, The Netherlands.
They were responsible for the creation of a few historical masterpieces, like the re-polishing of the Koh i Noor, mounted in the Crown of Queen Mary, to be admired in the Tower of London, amongst the other Crown Jewels of the United Kingdom and the Dresden Green Diamond, which belongs to the Saxon dynasty.
