Yep, I agree.
Most chatoyant wood species?

@chatometry, This is a very long thread so maybe this was covered, but I’ll risk asking anyway. Have you tried checking for chatoyancy before and after roasting a piece of curly maple (or other wood that do well with torrefication)?
See this thread for more details at my roasting test: https://woodbarter.com/threads/torrified-maple-test.46739/#post-649347

Well... we are not equipped for roasting wood :(
I will see if I can find someone who can bake some...
Have you tried other wood types?

See the list of torrefied woods at this site:
https://www.curlymaplewood.com/Roasted-Torrefied-Woods_c_89.html
Once you see the prices then you will understand I’m choosing to do the roasting at home. Luckily my wife wants a new oven soon so she doesn’t mind me experimenting with our old stove as long as the fumes can be exhausted outside.
You don’t need too- being that you are in Europe, there are Scandinavian countries who introduced this thermal treatment. You should be able to find vendors for flooring, decking, sauna and for guitar building woods that you should be able to get samples from. Just make sure you get the color range that goes from violin amber to the darker amber root beer. Pretty sure that will affect the chatoyance grading going from light to dark.

Thanks for the suggestion.
We tested samples from 12 more logs confirming Koa as n.1 for chatoyance.
These are some nice examples:

Tempted to see if I can make that set into a screen saver!

If you wish to try I can provide higher resolution gifs...
Thanks but I only use a cell phone. I don't even know how to switch screen savers on it. It is a very nice set of pictures though.

We uploaded a lot of gifs on these pages, split by type of figure.
I just wanted to highlight this one below; not nice indeed, but due to the presence of flecks it shows just barely visible chatoyance on wenge, which I had never noticed before.

Very cool. Thanks for posting.

For those of you who (like me) had never seen some chatoyant Cocobolo; as usual, no finish and sanding up to 1500-grit.
These are just to show nice examples on other wood species...

We have a new n.1!!!!
Data from Australian Blackwood (30.0 PZC on average of samples from 7 different logs) are much higher than Koa (26.4 PZC on average of samples from 20 different logs).
However from my limited experience, and @Arn213 may support on this, Koa is significantly more figured on average.
Another interesting new find is Queensland Maple (Flindersia Brayleyana) with more than 24 PZC on average. Does this match you experience?

Is your Queensland Maple of a commercial origin? The color expressed does not match well with F. brayleyana but does better with F. pimenteliana. Same thoughts when looking at vessel lengths.

The gif I posted is from a commercial source which, however, seems quite reliable to me. Anyway, this one looks similar:

I think its Zanthoxylum flavum or spp.

It looks like very cool stuff!
We don't have any data about that genus.
