For a Standard level hearthstone, I have no problem with more than one person having duplicates of the same rock, especially with the limited numbers of hearthstones there is to choose from. I don't want to see you having two of the same kind on the character, though. Diversify. Using Psychie's character for an example, she has the Bamboo one, and another 2 dot stone that provides water when it is buried in the earth.
With the Greater hearthstones, I have more of an issue of two or more characters sharing them. The higher level stones are supposed to be very rare, so how is it that more than one person has the same stone in the Circle? At that point, it would most likely be a 'first come, first served' situation.
