HONDURAN ROSEWOOD​

Rosul / Dalbergia stevensonii

Local Tree
Palisandro de Honduras, Honduras Rosenholz, Palissandre du Honduras
Distribution & Tree
Guatemalan rosewood or rosul historically occurred in large concentrations between Sarstoon and Monkey Rivers in Guatemala and Belize, particularly along rivers. It is one of at least four species within the Dalbergia genus of true rosewoods found in Guatemala and the most common in the Izabal department. It attains a height of 30 meters, with trunk diameters up to 90 centimeters. Trunks are often short and forked at about 7.5 meters from the ground. Mature trees often host wasp, bee and ant colonies.
Wood Appearance
Rosul’s heartwood is pinkish-brown to purple with alternating dark and light zones forming a very attractive figure, distinct from yellowish sapwood. Its texture is medium to fine with a grain generally straight to slightly interwoven. Its luster is low to medium. The fresh wood has an aromatic odor which fades over time.
Processing Properties
Rosul is moderately difficult to saw and machine due to its hardness. It’s excellent for turning and finishes well. It can be oily and, when so, difficult to glue. It is well suited for turnery.
Strength & Durability
Rosul’s heartwood is highly durable, resistant to termites, fungi and dry wood borers.
Wood Uses
It’s used for musical instrument components, veneers for fine furniture and cabinets, brush backs, knife handles, fine turnery, cheese sets, and many specialty items.
Ecological & Social Importance

Rosul has similarities to granadillo (Dalbergia tucurensis), but is significantly denser (930–1,170 kg/cm3 versus 650–820 kg/cm3). Rosul is medium to dark pinkish brown with dark streaks whereas granadillo is yellow brown to brown sometimes with dark streaks. Rosul is on the CITES appendix II and granadillo CITES appendix III
