Amelia d’Orleans, the first daughter to Philippe Comte de Paris and Marie Isabelle d’Orleans, married Carlos I of Portugal (reigned 1889-1908) in 1886. In the same year, Leitao e Irmao were commissioned to create jewels for Princess Amelia on the occasion of her wedding, and were later appointed as Royal Jewellers.
