Thanks. I'm glade I grabbed it then, i have been wanting to try one for years and being in Australia haven't seen one around. I just happened to come across a stone for auction and thought I would search completed auctions and bingo. Contacted the seller who re-listed it for me.Yes, they're Thuris. The Star label is pretty rare. I vaguely remember someone telling me they were marketed in Greece/Turkey? Under that label.
I've only seen a few in years of looking in Europe. They seem far more common in the USA than even Germany and Germany has other other slate producing areas. I have found a couple of wopper dark Thuris in Germany, but never a green, grey or yellow.Tim, is that esher as black as it looks?
Nice find, they seem much more abundant on your side!
