Color/Appearance: Brazilian Rosewood can vary in color from a darker chocolate brown to a lighter purplish or reddish brown, with darker contrasting streaks. The black streaks can sometimes form a unique grain pattern that is sometimes referred to as “spider-webbing” or “landscape,” very similar to Ziricote. Lighter yellowish sapwood is clearly demarcated from the heartwood.
Grain/Texture: Brazilian Rosewood has a uniform, medium to coarse texture with medium-sized open pores. The grain tends to be straight, but can occasionally be interlocked, spiraled, or wavy.
Endgrain: Diffuse-porous; medium to large pores in no specific arrangement; solitary and radial multiples of 2-3; mineral deposits occasionally present; growth rings indistinct; rays not visible without lens; parenchyma banded (seemingly marginal), apotracheal parenchyma diffuse-in-aggregates, paratracheal parenchyma vasicentric, sometimes weakly aliform.
Rot Resistance: Heartwood is rated as very durable to decay resistance, and is also resistant to insect attack.
Workability: Easy to work with both hand and machine tools, though it may have a slight blunting effect on cutting edges. Brazilian Rosewood turns, and finishes well, though it can sometimes be difficult to glue due to its high natural oil content.
Odor: Has a distinct, rose-like scent when being worked.
Allergies/Toxicity: Although severe reactions are quite uncommon, Brazilian Rosewood has been reported as a sensitizer. Usually most common reactions simply include eye and skin irritation. See the articles Wood Allergies and Toxicity and Wood Dust Safety for more information.
Pricing/Availability: Likely to be very expensive, and from questionable sources. Trade of Brazilian Rosewood is highly regulated, and sales are generally limited to reclaimed or pre-existing pieces of lumber.
Sustainability: Brazilian Rosewood is listed in CITES Appendix I, which is the most restrictive appendix, and also includes finished products made of the wood. It is the only species whose listing supersedes the already restrictive genus-wide restriction on all Dalbergia species listed in appendix II. It is also listed on the IUCN Red List as vulnerable due to a population reduction of over 20% in the past three generations, caused by a decline in its natural range, and exploitation.
Common Uses: Veneer, fine furniture, cabinetry, flooring, musical instruments (acoustic guitars, piano cases, etc.), turned objects, and other small wooden specialty items.
Comments: Brazilian Rosewood, like other exploited hardwoods such as Cuban Mahogany or Teak, has earned worldwide fame. Historically, it has perhaps been the species most frequently associated with the term “Rosewood,” and with its strength, hardness, stability, beauty, and acoustic properties, it’s easy to see why Dalbergia nigra has been used for everything from flooring to xylophone keys.
Due to the high demand and limited supply of Brazilian Rosewood, and its continued exploitation in recent decades, it has been listed in the most restrictive category of endangered species: CITES Appendix I. Not only is the lumber restricted from being imported or exported from country to country, but even finished products made of Brazilian Rosewood may not cross international boundaries.
Because of these heavy (yet justifiable) restrictions, several substitutes from the Dalbergia genus have been used in recent years, such as East Indian Rosewood, Honduran Rosewood, and Cocobolo; though perhaps the closest rosewood in terms of color and appearance may be Amazon Rosewood (Dalbergia spruceana)—another hard-to-find and pricey rosewood, though not CITES listed as Brazilian Rosewood.
