Ebony will be next. There is only one legal source of Ebony on the planet because of over harvest and the stupidity of only using the pure black wood. Tons of ebony was cut down and just left on the forest floor because only the blackest would do. Well, those days are over. We better get used to the fact that a lot of the woods that were once abundant are no longer available. So other wood will be replacing our favorites. Or synthetics will have to do the job...
At the time, a number of years ago, this was not an issue. There were more than one exact wood types that would come under each category; Bud Rosewood, Blood Rosewood, Golden Rosewood and even Rosewood.
All of this discussion of false advertising and such is now a moot point. All Rosewood types have been banned, along with Sheesham and Bubinga and a few others.
There has to be some kind of wood suitable for dark Chess pieces that is available in India that is not banned and will be plentiful enough for manufacturing use.
If there are none, then the Indian artisans that currently make Chess pieces will need to find sources to import the woods they need. And failing that, they will simply go to staining boxwood for dark pieces, lowering the quality of all sets produced in India.
And if all that happens we very well might see a different geographical area come to prominence for producing high quality Chess sets.
This will be interesting to watch.
