An ancient seal found in a Jerusalem archaeological dig

The Jerusalem Post reports:

A seal impression belonging to a minister of the Biblical King Zedekiah which dates back 2,600 years has been uncovered completely intact during an archeological dig in Jerusalem's ancient City of David, a prominent Israeli archeologist said on Thursday.

The seal impression, or bulla, with the name Gedalyahu ben Pashur, who served as minister to King Zedekiah (597-586 BCE) according to the Book of Jeremiah, was found just meters away from a separate seal impression of another of Zedekia's ministers, Yehukual ben Shelemyahu, which was uncovered three years ago, said Prof. Eilat Mazar who is leading the dig at the site.

I think I will suspend my belief in this story, what was found, whether it is indeed a 2,600 year old bulla, until I hear what Nadia abu el Haj has to say about it. Yes, the same most-recently tenured Nadia who owes her fame and good fortune to her anti-Zionist thesis which claims that "the modern Jewish/Israeli belief in ancient Israelite origins is not understood as pure political fabrication."

After all, it does look a bit suspicious, doesn't it, that an ancient seal of an Israelite kingdom should be found right at the site where Jews always believed the ancient Israelite temple was situated, doesn't it?

And anyway, what kind of a solid proof does an actual artefact provide, compared with the unfalsifiable proof of Islamic claims over the Temple Mount?
