What kind of wood is this?

My dad was in Thailand recently and brought me back a plank of wood of unknown variety:

It’s really quite beautiful. I doubt that shows through on the monitor. The heartwood is a pinkish/reddish cast, while the sapwood looks whitish in comparison, it’s still got a slight yellow / pink hue (close to cherry). There’s even some spalting in there as well.

This particular piece measures 17.875×7.75×1.25 and is surprisingly dense. It weights 6.8 lbs, which would put the density in the neighborhood of 60-70 lb/ft^3.

One thing to note is that while he was in Thailand, I believe this wood actually came from Laos. I’ve looked around and tried to figure it out myself, and my best guess based on look is Borneo Rosewood (https://www.cookwoods.com/lumber-site/shop/borneo-rosewood-8/). Not really Laos but still SW Asia. Problem is, at least compared to the slabs that they have on that website, density seems to be off by up to 50%.

Any ideas? Also, wood type aside, I’m setting this piece aside for something special. No idea what to make with it yet though, so I’m open to suggestions. I’d rather not resaw it but mainly because I’m just not very good at it yet.
