Ebonystar is laminate, what you would use on a kitchen benchtop for example. The "traditional" Ebony Star laminate is #4552-50 by Wilsonart which is no longer made. It came to prominence after is was recommended in Dave Kreige's book on building dobs back in the '90s.
I have purchased some from this source
http://www.suntactics.com/EbonyStar/ in the US
Alex Massey has some, which I have also purchased for my 8" and it works perfectly well but you would have to check with him if it is #4552. It is possible to obtain it from kitchen and cabinet makers, as there is laminate sold as Ebony Star but it is not #4552 and you would need to order quite large sheets and cut them yourself.
What type of dob do you have by the way?
