Caviuna
Scientific name: Dalbergia miscolobium
Overview
Caviuna is a tropical to subtropical South American hardwood belonging to the Fabaceae family and the Dalbergia genus, which contains the true rosewoods. Dalbergia miscolobium is native primarily to Brazil and occurs in woodland and savanna environments, including portions of the Cerrado.
The heartwood generally ranges from medium reddish brown to dark brown and may contain darker brown, purplish, or nearly black streaks. Sapwood is considerably paler and normally well differentiated from the heartwood. Grain can range from straight to interlocked or irregular, while texture is generally fine to medium.
Caviuna is not as internationally familiar as Brazilian Rosewood or several other commercial Dalbergia species, but its rich coloration and potentially attractive figure make it noteworthy for furniture, turning, carving, decorative objects, and collector specimens. As with other Dalbergia woods, legal sourcing and current international trade regulations should be considered when acquiring or transporting material.
Quick Facts
- Common Name: Caviuna
- Scientific Name: Dalbergia miscolobium
- Region: South American Hardwoods
- Tree Size: Approximately 25–50 ft (8–15 m) tall, with dimensions varying considerably according to habitat
- Average Dried Weight: Reliable standardized species-specific value not widely documented
- Janka Hardness: Reliable standardized species-specific value not widely documented
- Grain: Straight to interlocked or irregular
- Texture: Fine to medium
Identification Characteristics
Caviuna generally produces reddish-brown to dark brown heartwood with darker brown, purplish-brown, or nearly black streaking potentially present in individual specimens. The heartwood may deepen and become more uniform with age and exposure.
Sapwood is generally pale cream to yellowish brown and contrasts strongly with the darker central wood. Grain can be straight, interlocked, or irregular, potentially creating attractive figure in selected material.
Key identification traits include:
- Reddish-brown to dark brown heartwood
- Occasional purplish or nearly black streaks
- Pale cream to yellowish-brown sapwood
- Strong heartwood and sapwood contrast
- Straight to interlocked grain
- Fine to medium texture
- Attractive natural luster
Working Properties
Caviuna can require careful machining because of its density and potentially irregular or interlocked grain. Sharp tools are recommended, particularly when planing or routing figured material.
Interlocked grain can produce tear-out, while harder material may increase cutting resistance. The fine to medium texture can produce an attractive polished surface when carefully sanded and finished.
- Machines reasonably well with sharp tools
- Interlocked grain may cause tear-out
- Turns well with appropriate tooling
- Suitable for detailed carving
- Sands to a smooth surface
- Can take an attractive polish
- Pre-drilling is advisable for fasteners
Safety Note
Wood dust from Dalbergia species has been associated with allergic and sensitization reactions in some woodworkers. Potential effects can include skin, eye, and respiratory irritation.
Effective dust extraction, respiratory protection, eye protection, and appropriate skin protection are recommended when machining or sanding Caviuna.
Common Uses
Its rich coloration, fine texture, attractive grain, and suitability for detailed woodworking make Caviuna appropriate for numerous specialty applications, including:
- Fine furniture
- Cabinetry
- Decorative veneer
- Wood turning
- Carving
- Inlay
- Decorative boxes
- Small specialty objects
- Musical instrument components
- Collector specimens
Sustainability & Notes
Caviuna occurs naturally in Brazil, including areas associated with the Cerrado, one of South America’s most biologically diverse ecosystems. Habitat conversion, agricultural expansion, fire-regime changes, and other land-use pressures can affect native woodland species within this region.
The Dalbergia genus is also subject to significant international conservation attention because numerous rosewood species have experienced heavy exploitation. International trade in Dalbergia material can be regulated under CITES, although requirements and exemptions can vary according to species, product type, and current regulations.
Buyers and collectors should favor legally sourced material with clear provenance and verify current regulations before international movement of wood or finished products.
Comparative Notes & Related Species
Brazilian Rosewood – One of the world’s best-known Dalbergia woods, famous for its rich brown coloration, dark streaking, acoustic properties, and historical use in fine furniture and musical instruments.
Kingwood – A highly decorative South American Dalbergia known for violet-brown coloration, dark striping, fine texture, and use in luxury furniture and small specialty work.
Tulipwood – Another Brazilian Dalbergia prized for its dramatic pink, yellow, violet, and reddish striping and primarily used for veneer, inlay, turning, and decorative objects.

Collector Notes
Caviuna is an especially interesting collector species because it represents a comparatively obscure Brazilian member of the true rosewood genus. A documented sample can substantially broaden a collection beyond the familiar commercial Dalbergia woods.
Displaying Caviuna alongside Brazilian Rosewood, Kingwood, Tulipwood, and other Dalbergia species provides an excellent comparison of the extraordinary coloration, streaking, grain, and texture found within the genus.
Because rosewood identification and trade regulations can be complicated, collector specimens should retain the scientific name Dalbergia miscolobium, geographic origin, acquisition date, supplier information, and any available provenance or legal documentation.
