Struck a gold mine today! Actually this has been a very good month as far as finding fine natural stones in the wild. ( I wish I could post picks but for some reason I haven't been able to lately). Question is, did they make (glue together) a combo green/blue Thuri stone ? (it's not a natural as you can see that there is a seem. It measures 10" x 2" (no label but some residue of some on the end.

Also in the same box with 7 other various hones was a 3 x 10 Coti ! It's glassy smooth so I am hesitant to lap it. It is slightly concave but not bad.
