It's really not what purity would have worn the night the news came in about the ship wrecked on its way to Tasmania.
Perhaps pearls would have been worn and there would have been little cakes set on plates with this pattern or something similar for the young ones, after the dancing.
Pottery found at Secret Beach near Hobart, Tasmania, from 1800s set in Sterling Silver and set around with White and cream freshwater pearls on Sterling silver head pins. The Cameo has been set in the blemish of the plate. It is vintage from the 70's.
The pendant is cm long x cm wide and the chain is sterling silver, cm long
