Diana had very early contact with the passion of her grandfather and her parents in the business and developed a growing interest in the art of jewellery through her education.

She studied architecture both in Porto and Venezia and completed her MA at the Faculty of Architecture in Porto. During her studies Diana gradually gained responsibilities within the brand. After establishing her own creative studio in 2012 she keeps her collaboration with Monseo since then.

Diana Vieira da Silva seeks to articulate Monseo DNA with new designs. She designed several iconic collections of which highlight Portuguese Story, Secret Garden and Exotica as well as Limited Edition series and bespoke pieces of jewellery. She considers challenging and very creative being engaged to design one of a kind pieces at the request of its customers, for being such a personal and custom made process. Passionate about architecture, arts and design, loves cities, and believe in slow living lifestyle. Diana can not resist to be amazed by the Portuguese culture and savoir faire.

The jewellery collection Portuguese Story is inspired in the Portuguese cultural heritage where several pieces of jewellery were inspired by architectural elements from an historic-portuguese icon.
