Value & Sustainability
- Estimated Market Value
- $8.00 to $15.00 per board foot depending on grade and width
- Wood Age Estimate
- Recently milled lumber, likely air or kiln dried within the last 1 to 3 years based on clean surface conditions and lack of heavy oxidation.

Workability
Excellent workability with both hand and machine tools. Glues, stains, and finishes very well, though care must be taken to avoid tear-out on irregular grain areas.
Finish Recommendations
Takes oil finishes (like Danish oil or tung oil), shellac, and varnishes exceptionally well, enhancing the rich chatoyance and depth of the brown tones.
Notable Features
Possesses a moderate natural shock resistance, distinct mild odor when freshly worked, and dimensional stability that makes it a favorite among woodworkers.
