The picture shows what I have been told are jade buttons that belonged to my great grandmother Ching Ah Fung. They certainly have a small extrusion of the back which is pierced and looks as if it could have been sewn to cloth to act as a button.
Family lore suggests they were a prized possession of hers.
Unfortunately a well meaning relative a long time ago had them mounted on this huge specially made brooch. I know the work was done in HK probably in the 1960s.
Any views or comments appreciated.
