Market Value & Sustainability
Estimated Market Value
$12.00 - $20.00 per board foot depending on width, grade, and local availability.
Wood Age Estimate
The visible oxidation and finish wear suggest a sample or piece of furniture approximately 10-20 years old.
Sustainability Status
Not listed in CITES Appendices or on the IUCN Red List; widely available and generally considered sustainable.
Workability
Excellent workability with hand and machine tools. Planes well, glues, and finishes superbly. Large pores may require filling for a glass-smooth finish.
Notable Features
Distinctive mild, spicy odor when being worked. Known for its excellent dimensional stability and shock resistance.
Finish Recommendations
Oil-based finishes (tung or linseed) to enhance natural figure, or wipe-on polyurethane for durability. Gel stains are rarely used as the natural color is highly prized.
Identification Confidence
High. The characteristic deep brown hue, pore structure, and dark grain streaks are hallmarks of Juglans nigra.
