Hi Everyone,

I'm coming in today with a fun one. This is a piece of wood I was gifted as a "mystery dense exotic" by a fellow woodworker. He's had it for many years, has no idea where its from, where he got it from - that ol chestnut. Anyway, he gave it to me as its the perfect size for my pieces. Question is what is it... This guy used to get in a lot of pretty high end, rare woods so really it could be anything!
I've done my usual analysis and have the following:

Density (specific gravity): 1.01
Odor: Fairly faint, but fragrant and slightly sour. Almost sour faint rosewood smell?
fluorescence: Water - blue/green very faint, ethanol - green.

An old piece, but certainly feels fairly oily and clogs my sand paper like it is!!
Side grain appears to have the same "feather grain" (thats what I call it - have no clue about what its proper name is) on the face which I see in madagascan rosewoods, Swartzia and some of the asian Dalbergias.
Colour is relatively brown but contrasting, with the dust being more of a dark red - I suspect deeper in itll seem more red too.
End grain is where it goes a bit up in the air. It doesnt LOOK to me like Swartzia end grain whatsoever, nor does it look to me like any of the usual madagascan rosewood candidates (wrong grain - 100% not baronii or greveana). end grain has a nigra-esque look to it in some ways but its definitely definitely not nigra either.
I have added a scale of 10mm onto the end grain if that is also helpful.
I've also added a magnified pic of end grain 3mm across from one side to the other. I tried to get a good shot in a couple of places, but theres so much end grain its hard to give a full view in such a small pic.

I do have a thought of what I think it might be, but I don't want to say yet as I would like to see if anyone else comes to the same conclusion based on the pictures. As always, thank you for your help!

Endgrain looks Dalbergia like. The splintery edge does not. The weight discounts 'nigra'. I have not really taken time to think on it. Spring is often 12 hour work days, weather pending.
Thank you!! You’ve come to the same conclusions as me on this one. Part of me wondered if this could actually be a piece of darker cochinchinensis but personally I am not sure

Hi James, I cannot find the thread I used before! I am going to cut a piece or Cocus to the dimensions you said you were looking for i.e. 150mm x 60mm x 25mm. Please let me know if you would be happy with anything smaller in any of the dimensions. The tulip wood, I want to sell half of it. I intend to saw it length ways which would give pieces around 217mm x 56mm x 27mm. I have had this piece for several decades, it came from John Boddies in Boroughbridge which ceased trading long ago. It may be a while before I get around to this……..Cheers, Chris.

Hi Chris,
That’s great, more than happy with those dimensions! Would you be willing to sell a couple of pieces of Cocus that size? Ideally I need to be able to get an even number of 2” squares from a blank if that’s helpful. So any clean pieces 2” square and 1” thick is fine!
Basically whatever you’re willing to sell :)
The tulipwood sounds good! If the Burmese Blackwood is still up for grabs too I’d definitely take that piece too.
