Very nice...and yes interesting block. I suppose it would be considered "translucent" although those are not typically so obviously unusual...especially in a photo...they tend to have a much more subtle difference from standard blocks...especially when new and unsmoked.
Very true.
On that difficult-to-describe note, I’ve toyed with the idea of penning a more true-to-detail designation system for wacky blocks, as I’ve seen many strange forms of meerschaum pipes, and I find “translucent” to be too general, as there are not only many different types, but many reoccurring silicate patterns and forms that differ while they still could fall under a certain grouping. They can be have great clear depths in blips and puddles, or whole shells of clearer silicate. Tiny speckles like fat separated from butter or splotches like rotten milk. Veins, cracks, and things that even I’d have trouble defining. It’s as interesting as can be to me.
The reason I picked this one up (and yes, I certainly understand some finding its appearance unappealing), is because of the many varied forms of “translucent” styles within. Usually one might find a “translucent” meer sporting one or two different patterns, like depths and tiny speckles here and there, or rarer still anything with veins as is often searched for at a chance to have one end up like Mr. Baki’s famed pipe:

But my new M. Cay has quite a bit going on in a good many ways that I don’t usually see together all on one pipe.
Messy and maybe even the ugliest pipe I’ve ever had, sure, but I love it.
Oh, and I will say this to those interested in strange meerschaum block pipes, just do a bit of scouring online through the ‘bay or on the ‘tsy. I got this pipe and my other craziest meer which I think just a page back on this very thread, for around $100-$120 each all said and done.
They may be a little rough around the edges, but there is certainly no reason you should have to go selling off your body parts in order to afford one.
