Color/Appearance: Heartwood is a pale to medium reddish brown, frequently with darker brown to black streaks throughout. Color tends to darken with age. Sapwood is a pale yellow to pinkish brown.

Grain/Texture: Grain irregular and/or interlocked. Fine uniform texture. Naturally lustrous.

Rot Resistance: Rated as very durable. Resistant to termites, though more susceptible to other insect attacks.

Workability: Generally hard to work with on account of its irregular grain and high density. Cebil also has a pronounced blunting effect on cutters. Turns well.

Odor: No characteristic odor.

Allergies/Toxicity: Besides the standard health risks associated with any type of wood dust, no further health reactions have been associated with curupay. See the articles Wood Allergies and Toxicityand Wood Dust Safetyfor more information.

Pricing/Availability: Sometimes available as flooring planks, as well as wide boards and slabs; occasionally offered as turning blanks as well. Prices should be in the mid-range for an imported exotic hardwood.

Sustainability: This wood species is not listed in the CITES Appendices, and is reported by the IUCN as being a species of least concern.

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

Comments: Sometimes sold as cebil by lumber dealers, or by the exaggerated namePatagonian rosewood by flooring dealers. Despite this common name, curupary is not closely related to the true rosewoods in the Dalbergia genus. Curupay is a dense hardwood with a highly variable streaked appearance not too unlike goncalo alves (Astronium graveolens).
