The following reference speaks of the white stone(s):
Rev 2:17 “If you have ears, listen to what the Spirit says to the churches. To everyone who wins the victory, I will give some of the hidden food. I will also give each one a white stone with a new name written on it. No one will know that name except the one who is given the stone. “
“This white stone is absolution from the guilt of sin, alluding to the ancient custom of giving a white stone to those acquitted on trial and a black stone to those condemned. The new name is the name of adoption: adopted persons took the name of the family into which they were adopted.” Note: I found this information on the white stone from Matthew Henry's Commentary Book)
