On paper, the Portuguese diamond is a large modern stone that lacks mystery or complexity. In reality, however, the Portuguese is one of the largest step-cut diamonds in the world, and unexpectedly, its size and simple cut exudes an astonishing brilliance. For these reasons, stonecutter Scott Sucher added a replica to his famous diamond collection and offers museum-quality replicas to expand yours as well.

Portuguese Diamond History

Compared to other famous diamonds, the Portuguese has a short history. The stone was likely found in the early 1900s, although where is disputed. Some believe the diamond was mined in Brazil, a Portuguese colony at the time, making the stone property of the Portuguese crown. But there is no documentation to authenticate this stone’s presence in the Portuguese Crown Jewels.

More likely, the stone was mined in South Africa and owned by a number of individuals before its acquisition by famous dancer Peggy Hopkins Joyce in 1928. Joyce sold the Portuguese diamond to Harry Winston in 1951, and he traded it to the Smithsonian in 1963 for nearly 4,000 carats of smaller diamonds.
