The Elendil stone of Emyn Beraid was-

This stone had 'special abilities' in which it was not in accord with the other palantiri. And that it could view the master stone kept in Tol Eressea in Valinor.

It is possible that the elves which traveled to Lindon did so to use the Elendil Stone. (an example of this are the elves Frodo and Sam meet in *Fellowship of the Ring* who are returning from Lindon led by Gildor)

However my question is: did Cirdan use this Palantir to communicate with the West and possibly pass messages along to the Wise?   It seemed the Valar did play some part in the affairs of Mmiddle-earth (sending Gandalf back, gusts of wind to aide Aragorn's ship etc.) and who better to communicate with than the literally ancient and wise elf that Cirdan is?
