Tiara with sapphires and diamonds belonging to the Duchess Isabella of Genoa, nee Elisabeth of Saxony, mother of Queen Margherita of the House of Savoy. (Isabella was the niece of the Princess Augusta who married Eugen Beauharnais, mother of Queen Josefina of Sweden, who herself was the source of so many Scandinavian crown jewels.) Possibly a gift from the duchess to Margherita on marriage to Prince Umberto of Savoy. Disassembles into five brooches.
Amadeo I (1845 – 1890) was the only King of Spain from the House of Savoy. He was the second son of King Vittorio Emanuele II of Italy & was known for most of his life as the Duke of Aosta, but reigned briefly as King of Spain from 1870 to 1873. He was elected by the Cortes as Spain's monarch in 1870, following the deposition of Isabella II, & sworn in the following year. He abdicated & returned to Italy in 1873, & the First Spanish Republic was declared as a result.
