According to 24-Hour-Museum -- and the Rolfe family -- these superb pearl earrings may have belonged to Pocahontas, AKA Lady Rebecca Rolfe:
It’s not known whether the hefty pearls really dangled from Pocahontas’ ears or not, but for Bly Straube, curator of the Jamestown Rediscovery project in the USA, the circumstantial evidence provides a decent case.
To start with pearls were often worn by Native American nobility, yet this pair has silver rims with steel point inlays, which suggests they were set in England. However, we do know that while imprisoned in the Tower of London the Earl of Northumberland repaired some earrings for Pocahontas.
"In 1866 a new bride of the Rolfe family was presented with them," Bly told the 24 Hour Museum, "and told that they were handed down through the generations and had been Pocahontas’ earrings."
