The House of Leitão was established at the end of the eighteenth century in the city of Porto, Portugal. In 1887 Leitão and Irmão were honoured with the title of Jewellers to the Portuguese Crown. They have served as jewellers to five kings of Portugal and Brazil. The Leitão and Irmão hallmark is the oldest in Portugal and the company continues to the present day.
