The establishment has had different locations throughout its history: it began in Espoz y Mina, then in Montera, from there to Carrera de San Jerónimo, and after the Civil War, to Calle de Alcalá. They made numerous jewels for Queen Isabel II and the ladies of the Court on the occasion of her wedding with Don Francisco de Asís de Borbón, Duke of Cádiz. Commissioned by Alfonso XIII, they made for Queen Victoria Eugenia the diamond tiara with dynastic fleurs-de-lis that she wore on her wedding day and that Queen Sofía sometimes wears today. They have also been architects of the crowns of the Child and of the Virgen del Pilar.
