At first glance it looks like an ebony (many are striped). It maybe PNG ebony which is similar.
I may be able to take a pic of some I have, show you tomorrow.

Here are some pics of 2 tropical striped ebony Dengue. The stripes vary quite a lot and are in the darker heartwood.
If its not these then its another ebony IMO.
Top one is PNG striped Ebony (Possibly Diospyros ferrea)
Bottom two are Borneo / Malaysian striped ebony (bot name on edge)
Colours are distorted as usual (they are not as pink / as this . Pinks should be more brown like the pic you showed)

Not discounting what Euge stated, but I would be surprised if Ebony was used due to cost.

There was a time when ebony logs that were not pure black were left in the field as they had little value YouTube
Not saying that anyof the logs left were harvested for other uses at a much cheaper rate, but why not?I got sick of sitting around doing nothing - so I took up meditation.

Yes. I agree cava, ebony is a very expensive wood, especially now. Perhaps this pic was of a VENEERED panel?
(This is quatersawn but not the all black wood which is even more pricey and less often sliced or cut for veneers)
Not many timbers have that black heartwood (even streaked) and these woods are always in high demand (read expensive). Everyone wants such darker woods for small items and such demand eg for musical instruments and veneers, results in very high prices

The highest value is in the dark heartwood. Everyone wants that and will pay for it.
Believe it or not such trees are beaten to scar / bruise their cambium layer introducing a fungus that causes a black wood to form. Some Australian Diospyros have black specks where bark damage occurred or regions where a branch broke and black heartwood formed there (its called Phytoalexin response (antimicrobials are made by plants) in response to infection. These accumulate in areas of pathogen infection. They are chemically diverse inhibitors (ie unique in colour, odour etc) and are characteristic of any particular plant species, including the ebonies.
I can show pics of some Aust ebonies if you wish.

I think it could be Queensland walnut (endiandra palmerstonii). There appears to be a join in the second dark stripe from the left, which would would indicate a veneer panel.

+1 for walnut, although I think it's more likely US walnut than Qld simply because of the brand.

when I first looked at this immediately thought of sasafras
I'm certainly not an expert as some of the other folk, just saying.

Here is a couple of known samples of Queensland walnut. These samples are from a long gone veneer mill from Cairns. This veneer was extensively exported to Japan and came back as furniture back in the 70's.

Definitely Queensland Walnut. I used tons of the stuff to make loudspeakers in the 70's but we could never match the colour of the Japanese product.
It appeared to be stained with a very light purple dye which was sprayed onto the veneer under the top coat to make it look more like American Walnut.
The local paint and stain manufacterers could not replicate the product so we produced our own version that was a hint of Wattyl mahogany FRS in an intermediate coat of laquer.
