During the Olympic Games in Munich, Germany in 1972, The Crown Prince met Miss Silvia Renate Sommerlath.
She was working at the Games as an interpreter and hostess. Silvia Sommerlath was born in Heidelberg on 23 December 1943. She is the daughter of Walther Sommerlath and his Brazilian wife Alice, née de Toledo, both now deceased.

The engagement of King Carl XVI Gustaf and Silvia Sommerlath was officially announced on 12 March 1976.

Together with Silvia’s parents (Carl Gustaf’s mother Sibylla had died four years earlier), Carl Gustaf and Silvia announced their engagement on March 12, 1976. Carl Gustaf and Silvia alluded to being “unofficially” engaged several months prior, but had decided to wait until Silvia had completed her duties at the Olympic Winter Games in Innsbruck before making it public.

Carl Gustaf gave his fiancée a single solitare ring set with a 2-carat diamond. The ring once belonged to his mother, Sibylla. Silvia was said to have been touched at receiving a ring with such history. Carl Gustaf also wore a traditional and customary plain gold engagement ring.
