Impossible to say from just pics, but the fact it has it's own fitted box and slurry stone means it is a quality stone.

Just wanted to throw mine up for fun and to share!
Comments and info on it would be great.

cool looking stones.

I was told that it's a Nakayama Maruichi and the color looks like kiita/asagi to me.. blue spot? It's as good if not better than my Ozuku Mizu Asagi and I enjoy the size for smilers!
Would it be safe to call it Kiita Asagi Kan(for the rings)

You are on the right track, but Elibul I just don't see the kiita yellow color.
Brooksie, you can see in you stone that the asagi and kiita are both from the tomae strata, your stones shares some of the transition between the asagi to kiita. Not fully yellow and a sort of kan color instead. The asagi is a gray/green/blue tomae stone, the kiita is a yellow tomae stone. A kiita stone will provide a yellow slurry, the asagi a white slurry that can have tints of yellow but will generally dry white.

There are 48 different tomae layers or stratas in the mines of Yamashiro, not every layer has kiita and in fact kiita is one of the rarer occurances in the mines. Kiita is a yellow stone and in some tomae layers are other types of color stones as you can see in the photos. A gray type of tomae stone with some rust/ocher/yellow is not a kiita stone and an asagi stone that has a hint of yellow in the slurry is not a kiita.

The asagi stones called Mizu Asagi are usually blue or with an under tone of blue. Mizu means water but water can be clear in a glass but green or blue in a lake or ocean so this term is very broad. The lovely asagi stones that are green with hints of blue and yellow are mineral rich and the yellow and blue minerals optically mix in our eye to make green much like the dot matrix is used in 3 color (4 color if you count the black) offset printing where your eye blends the 3 color to make various colors including yellow and blue to make green.

All of these unique color stones are becoming more and more rare on the market, there are lots of gray stones still left in storage because they were not regarded as easy to use, hence the "for experts only" designation. The color stones were always the easiest to use and scarce, so now there are becoming even harder to find.

Sorry to disappoint anyone who thinks that a bit of kan/rust looks like a kiita stone, but a kiita really has to be all yellow of various shades and intensities of yellow or what they call in Japan "tomago", egg color.
