This unusual necklace has a banded agate pendant that is circa early 1900's and the chain is contemporary. Unfortunatly this necklace was cleaned so it is bright and shiney as if it were new, being silver however it will darken up with time. The banded agate pendant is very dark and has some lighter grey bands going through it. It measures 20 X 16mm and the chain is 18 inches lon and 2mm wide. This piece is in very good condition.
