I recently purchased two inexpensive stones from him/her (?), but I haven't received them yet. They are due mid November... I made an offer on one and won the other on auction.... sorry I can't be more help... I'll let you know what I think when I get them.
After reading a bit on toolhaus as TL suggested, I looked at their photos - they look so enhanced to me - with no additional shots such as side or back view - that I think this is a case where you take a chance and see what you get. I really can't tell anything from the photos, fwiw. However, always looking for a new good seller, I will await your findings with bated (baited?) breath
