I've seen some "Certified Ethical" ebony sets, but the vast majority is poached. And what is the point? A nicely stained maple and walnut set seems less likely to crack anyway.
Zombie, my point exactly.
If ebony is being poached, why spend a dime to support a crime?
If you want something rare, consider red sandalwood. Many think it looks nicer than ebony, and there's still some NOS stock available. But once it's gone, don't expect any new sets, as red sandalwood is on the endagered species list. It's banned from export in India, and import in the U.S. and most other countries.
