I'm no "expert" but the two biggest kanji looks like; 大平, Ohira .

It seems like there has been 別上 in top right corner
( 別上 = "Superior selected grade" )

the other kanji under 大平, could be something like 礦山

thebigG, could you make a photo of the reverse side of this stone?

I want to take a look at "hada" ( "hada" is for skin in Japanese ).

No worries mate here are two wet and one dry there is not any lacquer on this stone yet and I'm not sure if I need to or just should lacquer the stone any advice would be appreciated thanks.http://s1226.photobucket.com/user/th...77e8.jpg.html]http://i1226.photobucket.com/albums/...psf40977e8.jpg[/URL]

Lacquering jnats these days is more of a choice then a necessity in most cases providing there are no lines and its a fairly dense stone. I do lacquer most of my stones whether they need it or not as it can bring out the colours and makes the skin look awesome :P

The stone you have looks like it has no line so there is not a huge chance of it cracking, but that doesn’t mean you shouldnt. :)

It is much better to lacquer the lateral faces of the stone even when it is not actually needed than to loose the stone because of delaminating or cracking.


It is a little strange to me that the reverse side of the stone has no hada. It looks like the stone is splitted from the bigger one.
For this reason if it would be my stone I'd cover with urushi not only the lateral faces but the reverse side also.

BTW acrylic, polyurethane, MSA or epoxy lacquer/sealer/compund are also good enough for protecting jnats.
