Hi Rick thats as good as it could get. Collectors do not like artefacts of this nature to be cleaned. the green patina created as a result of many years in the ground adds to the authenticity of the piece. i have a detailed report from the portable antiquity scheme giving me the history of the piece. i guess i am pretty lucky to have permission on such history soacked land. Some items i attempt to preserve, however you have to be careful as some preservatives can taint and change the colour of the enamel. This is pendant number 5 i have found now. will post othres for all to see some time soon.
