Common Uses: Flooring, exterior construction, furniture, and turned objects.

Comments: Sometimes sold as Curupay by lumber dealers, or by the exaggerated name Patagonian Rosewood by flooring dealers, Cebil is a dense hardwood with a highly variable streaked appearance not too unlike Goncalo Alves (Astronium graveolens).

Way back when I grow up in the 60s, there was one tree from Paraguay and Argentina called “Petiribi also Loro” they where using it for furniture and also flooring, can anybody recall that, or perhaps know the real name. Thanks

Curupay (or Curupau, as we call it) is among my personal favourite timbers. It is great choice for wooden flooring for those who are after exotic timber floor. The dark streaks gives an unique character of the wood. It is also among the hardest and most durable wooden flooring options.
