The discovery of spindle whorls and amber beads in Sark reveals a Bronze Age population engaged in Atlantic trade and small-scale industry.
Sir Barry Cunliffe, the lead archaeologist, said this showed sheep had been reared on Sark for thousands of years.
Excavations of an ancient settlement near the Sark Mill revealed a "surprising number" of the weights, used for working wool.
