Adriana Da Riva Currently practising as an acclaimed architect (current clients include Balenciaga and Tom Ford) it is no surprise Da Riva's jewellery is modern and graphic. Aside from placing large gems in minimal architectural settings, her signature is the ability to dismantle or add to her jewellery to change its look and function. The Sirius ring is an award-winning example of this. www.adrianadariva.com.br
