RSo= Thor-Korut Ky, goldsmith Rauno Sorvo.
830= silver
K8=1967
 
Rauno Sorvo seems to have mainly worked in Turku (Åbo), a city known for its goldsmithing tradition. His style fits into the Scandinavian design of the time: clean lines, solid silver, sometimes modernist or abstract inspiration. He is not as famous as well-known names like Pentti Sarpaneva or Tapio Wirkkala, but his jewelry is appreciated by collectors for its craftsmanship quality and typically Finnish authenticity.​
No detailed biography, major exhibition, or official international recognition is currently associated with him, which means his work is mainly known through pieces circulating on the second-hand or vintage market.
