I have one piece that matches, but it's only on one side. The other side is sapwood. It's really not a good piece.
There's a supplier that sells it as Asian ebony where you can pick the specific piece you want. They have the best deal I have seen on that wood. The few other suppliers seem to think the stuff is gold. I used to be able to buy it for $8/ea for 18" squares but that source dried up.
