It could be mango. Smells sweet/sour.
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.......
