Jatoba (Brazilian Cherry / Courbaril)

Jatoba is the wood of Hymenaea courbaril, a large legume tree of the tropical Americas that ranges from southern Mexico and the Caribbean down through Central America and across the Amazon Basin into Brazil. It is widely sold in the flooring trade as Brazilian Cherry, though it is unrelated to true cherry (Prunus); 'Courbaril' is its other common international name, and it is known regionally as guapinol, algarrobo, and West Indian locust. The tree is also the historic source of a copal-type resin.

At a glance the timber is heavy, dense, and very hard, with a warm palette that runs from golden-honey brown to a deep reddish or salmon brown, often streaked with darker striping. It combines high strength, good decay resistance, and a rich color that deepens with light exposure, which together explain its dominance as an imported hardwood flooring and its popularity for furniture, stair parts, and turnery. On this sample the grain reads straight and fine with subtle variation, and the color is a golden-honey brown with warm undertones.

The heartwood ranges from a light golden or salmon brown to a darker orange-brown and reddish brown, frequently marked with contrasting darker growth striping. The sapwood is a sharply demarcated pale grey to yellowish white. A notable trait is that the heartwood is photosensitive and darkens markedly on exposure to light, ripening from honey tones toward a deeper red-brown over weeks and months. The grain is typically interlocked, though it can appear straight on flat-sawn faces; texture is medium to fairly coarse but even, with a good natural luster. On this sample the grain is straight and fine with subtle variation.

Jatoba is a genuinely heavy, dense wood, with a Janka hardness of roughly 2,690 lbf — very hard, well above red oak (~1,290) and hickory (~1,820), which is the main reason it succeeds as a high-traffic flooring wood. It is high in strength, stiffness, and crushing resistance, and it is notably tough and shock-resistant.

Natural durability is good: the heartwood is rated durable to very durable with respect to decay, and it resists most fungal attack, though it can be susceptible to some insect and marine borer attack. The pale sapwood is not durable. These properties make it a sound choice for demanding interior use and for exterior applications when properly detailed.

Flooring is Jatoba's flagship use: sold as 'Brazilian Cherry,' it is one of the most common imported hardwood floors, valued for its hardness, wear resistance, and warm color. Its density and strength also suit it to stair treads, handrails, and other high-wear architectural millwork.

Beyond flooring it is used for furniture and cabinetry, tool handles and other impact-tolerant items, sporting goods, ship and boat building, railroad ties, and heavy construction and exterior joinery where its durability is an asset. Its density and even texture make it a good turning wood for bowls, spindles, and small decorative pieces, and it takes a fine polish. The tree also yields a resin historically used in varnishes and incense.

Jatoba is hard, dense, and demanding on tooling. Its high density and often interlocked grain make it moderately difficult to work: it can blunt cutting edges and is prone to tear-out on interlocked or figured stock, so sharp, carbide-tipped tooling, a reduced cutting angle, and light finishing cuts give the best surface. It can be hard on saw blades and planer knives, and it has a moderate blunting effect. It is dense enough that pre-boring is advisable for nailing and screwing to avoid splitting.

Despite the density it turns and finishes well, taking a high natural polish, and glue-up is generally satisfactory although the dense, sometimes oily surface warrants clean, freshly machined faces and attention to open time. It responds well to standard finishes. Note that the wood moves a fair amount and has high shrinkage, so it should be well acclimated and dried before use, and wide flooring boards are best sourced kiln-dried and given time to equalize.

On safety, Jatoba is not a severely toxic wood, but its fine dust can cause respiratory irritation and, in some workers, skin irritation; effective dust extraction and a respirator are recommended when machining or sanding. The species is not listed on CITES and faces no international trade restrictions.

Jatoba is widely available and moderately priced for an imported tropical hardwood. It is imported in large volumes as flooring and, to a lesser degree, as lumber and turning stock, so both pre-finished flooring and rough boards are relatively easy to obtain. Prices are typically in the moderate range for an exotic — higher than domestic oak but well below premium cabinet exotics.

The species is not listed under CITES and is not currently assessed as threatened; it is a wide-ranging, common tree across its native range. As with any tropical timber harvested from the Amazon and Central American forests, responsibly sourced or FSC-certified stock is the preferable choice to ensure legal, sustainable origin. Availability is generally stable, particularly in the flooring market where it remains a staple product.
