Filigrana, or “gold filigree,” is a jewelry technique that predates Roman times, making it one of the oldest in the world. The most traditional (and commonly found) forms in Portugal are the curved “Viana” hearts which have become a symbol of the country. At the top end, a new wave of designers are interpreting gold anew; at the forefront is Luisa Rosas, who has joined the family business named after her father, David Rosas. Luisa’s training as an architect and her work alongside one of Portugal’s most acclaimed architects, Pritzker Prize winner Eduardo Souto de Moura, is evident in her fluid 18-karat-gold designs. So for the ultimate wearable souvenir, head to the David Rosas boutique at Quinta Shopping just across from the hotel. There are plenty of eye-catching baubles to choose from, but we are smitten with Luisa’s collection of tactile rings which draw on nature-wood, water, grass, and stone - for inspiration.
