If you been following pricing, ALL wood materials, even pine lumber at Home Depot has been going up continuously for a long time. Most of the exotic woods come from tropical/rainforest type parts of the world and supply is dwindling due to conservation, and a move in the third world to try to get havesting to a sustainable level. Additionally, all this wood is imported and the value of the dollar has at the same time been going down as the supplies of wood have been increasing.
In some instances there is almost no new, or extremely little of some wood species from some coutries available now. Madagascar has almost eliminated any harvest of ebony for export, for example. Too much Indian Rosewood is being harvested and wasted on furniture manufacture; you will see that pricing continue to escalate. ( If you live in a big city, firebomb any "Indian Rosewoood" furniture stores AFTER you pull out any pieces of furniture suitable for rework into bodies.necks!!!!)
