Ok in another thread a couple of months ago I discussed the color change of pink ivory and I showed my sample and many people said that it looked very brown.
Well now I managed to get a new sample to compare and they do look a lot different although I do remember my original sample was pink back in the day.... not sure if it was this pink. Well end grain (pink ivory needs more work) looks quite similar I was thinking maybe my sample was actually B. discolor but I would have to get a sample to compare.
Any Guesses or suggestions?

On the right, you can see my sample, and on the left the new sample

First is end grain picture is my original sample and second the new sample

All I can add is that the color doesn't look quite like pink ivory but doesn't rule it out, and the end grain seems more or less consistent with pink ivory although a bit hard to tell with the lack of full detail. Maybe you can check it against my site if you have a 10X loupe. Also, I corrected your title from "mistery" to "mystery" so it looks normal.

I remember @Mr. Peet response posting on Barry’s thread on the mystery wood that @Gonzalodqa sample is “brown ivory” (berchemia discolor). It is characterized with “red-brown with pink tinge”. The hue to the right is what I have seen more off and the 16/4 curly stock I have- it is red ivory/pink ivory (berchemia zeyheri).

You should put the older sample away in a drawer away from natural light and leave the new red pink ivory out to see what happens to the color after 6 months, 12 months, 18 months and 24 months- photographing it would be good at the same location and the same time of the day.

Are they raw without a finish or do they have a finish? If they have a finish, what did you use?

the old sample has shellac (3 coats) the new samples is unfinished. I am planing to get a B. discolor and compare them. I have to talk to my friend at NEHOSOC to see if they have any sample left.
I will post more about it as it develops.
PS: the picture idea is great I will follow it to see if something changes

Clear shellac versus amber shellac based on what you use will transform the hue of the subject. Basic color theory of mixing yellow with pink = peach to orange. Any finish with a yellow tint or aged tint will result to a color change of the original hue. If you use nitrocellulose lacquer, the lacquer will yellow over time and will change the original hue and will become warmer. Let’s take curly maple as example- it has a base color hue of yellow (really pale version). You see this effect on guitars when they use a blue dye on the maple, then they spray clear. At the end of it depending on the concentration of the blue dye use (some use it straight and some dilute it with water, alcohol, etc.)- it will not be purely blue and you will get a cast of blue-green and over the time as it ages, the blue-green will be more apparent.

I mix shellac and denatured alcohol so I can get better flow and to keep the color as new as possible- that has been my luck with the red pink ivory that I have.

I also use clear shellac basically because I do want to preserve my samples color.
I will follow how this new sample reacts to finish, although I don’t think I will be able to finish it until in a couple of weeks
