But if this one is from Clara, not sure ... I agree with Niels who is much more baryte-educated than me, this is really not a typical Clara specimen but it doesn't look too strange to rule it out ... :-/
Maybe a little question mark on the label would do it?

Niels and Tobi,
I browsed through all of the Greek barite photos on Mindat and there are a couple of Lavrion barite specimens from the Sounion Mine that are remarkably similar to the one I have. I am starting to believe that my specimen is from Greece, not Clara. Again thanks for the input.
Michael
