Market Value & Sustainability

Estimated Market Value

$12.00 - $20.00 per board foot for figured/curly stock.

Wood Age Estimate

30-60 years based on the deep oxidation of the finish and surface patina wear.

Sustainability Status

Not listed in CITES Appendices or on the IUCN Red List; widely available and sustainable in its native range.

Workability

Excellent with hand and machine tools. Responds well to steaming. Can have tearout in figured areas if blades are not extremely sharp.

Notable Features

Distinctive mild, spicy scent when worked. Known for excellent dimensional stability and shock resistance.

Finish Recommendations

Oil-based finishes (Tung or Linseed) to pop the curly figure, followed by polyurethane or lacquer for protection.

Identification Confidence

Medium. The color and fiddleback figure are highly characteristic of Walnut, though some stained Maples or Birch can mimic this appearance.
