George turned up today with a little collection of mainly Scottish Minerals.
This is some native silver from Alva Mine, Central Scotland.
8mm across - rare stuff!
The discovery of a native silver deposit in 1715 also coincided with the Jacobite rebellion led to a remarkable story of fortunes made and lost along with betrayal and intrigue.
In the late 19th century the mines were later worked for cobalt which was sold Buchan's Pottery of Portobello near Edinburgh to make blue glaze.
