Definitely not Spanish cedar. I have Cuban Mahogany and genuine. I also have some Spanish. And it doesn’t look like either. I have yet to cross cut them. I was reading up on Mexican mahogany. The tree came from Florida.
I was told when I got it. They thought it might be mahogany.
My Cuban is much more orangey that my genuine if I recall. I only have a few pieces of Cuban. Lots of the other stuff thou. I will try and take a picture of all together. I’ll even Include the Spanish cedar I have. But the SC is boring and quartersawn.
I believe that is mango (mangifera indica)- spritz some water on it and you should get a sweet/sour aroma and a golden yellow color. Mottled figure is present in mango. I supplied a piece (it came from Hawaii though) to a luthier friend if you want to see a finish guitar out of it. Mango does have similar mahogany like face grain structure and density.
I told you so . Wet the slab and take a photo and post it. I’ve handled flat sawn material too and with similar grain make up as what you posted.
Anyhow, let me post the best quartered mango from Hawaii that has passed my hands - long gone and these were close to 4” thick.......lots of guitar sets. I’ll post 2 photo’s to give you an idea of the different figuring and color way (1st one is flame) and 2nd one is block mottled- I believe the color way on yours would be similar to this. The mango lumber in Hawaii has the coolest coloration that is yellow to yellow-orange that has peach, tans, greens, orange, grays, etc.. Like I said the grain make up is reminiscent of genuine mahogany including density......
A finished electric guitar below from a luthier friend of mine that I supplied the mango billet for (including the pernambuco fretboard)- different log as you can see how the colors are sprinkled in the face grain.......
