Police are searching for the rest of a gang that tied up businessman Richard Barnfather and his fiancee at their home in Shropshire.
One of the gang, Nathan McDonald, was jailed yesterday for almost ten years for his part in the raid.
Police are offering £14,000 for information leading to further arrests.
Jewellery stolen includes a diamond solitaire ring worth £25,000 and a bracelet with diamonds all the way around.
A White Cartier and Breitling watch were also taken during the robbery.
Richard Barnfather said the experience was so surreal. He watched his partner being manhandled and degraded. He said she has suffered physical and mental scarring.
