Hi Alipersia,
I'm not sure these beads are real ancient, the real ancient beads are not so white, they seem to have been dipped in the acide to give them an old aspect. the hole too seems too white. i think these are copies (India, China....) that were aged. There are two pics of some ancient preislamic beads from excavation, the colors are not regular, not so white......The wear of the various colors are irregular
best regards!
