Market Value & Sustainability
Estimated Market Value
$15.00 - $30.00 per board foot for highly figured/burl Grade A material
Wood Age Estimate
Freshly turned green or semi-dry wood; the lack of deep oxidation suggests it was recently harvested/cut
Sustainability Status
Least Concern (IUCN); widely available and not CITES listed, though slow-growing
Workability
Generally excellent with hand and machine tools, though figured areas like this are prone to tearout and require very sharp tools and light cuts
Notable Features
Distinctive mild spicy scent when worked; contains juglone which can be an irritant; excellent dimensional stability once dried
Finish Recommendations
Oil-based finishes (Tung oil or Danish oil) to pop the figure, followed by shellac or high-quality wax for a natural feel
Identification Confidence
High; the characteristic chocolate-brown hue, contrast with sapwood, and specific grain swirl patterns are classic indicators of Juglans nigra burl/Black Walnut burl.
