This is an unusual antique Danish 826 silver brooch with filigree wire work over a base plate. The brooch is marked with the maker's name C. Skyum and the silver grade S826. Metal also tests positive for silver of slightly less than sterling grade.
This brooch measures 2.25" x .875". It weighs 10 gr.
Condition is good, with patina left intact and unpolished.
This is a nice example of Danish regional jewelry.
