English Walnut (Burl/Claro Walnut variant)
Juglans regia • Hardwood
Grain Pattern
Highly irregular and figured with heavy burl clusters, swirls, and circular grain patterns known as 'eyes'. Significant chatoyancy and ripple figure is visible in the lower section.
Color Description
Medium to light golden-brown with darker chocolate brown streaks and dark inclusions. High natural luster; heartwood will likely darken and develop a warmer patina with age.
Hardness Rating
1,220 lbf (Hard)
Durability Rating
Moderately Durable to Durable; heartwood is resistant to decay but susceptible to insect attack.
Common Uses
Fine furniture, high-end gunstocks, knife handles, luxury automotive trim, musical instruments, and veneers.
Geographic Origin
Native to Europe and Western Asia; widely cultivated in Western North America (specifically California).
Market Value & Sustainability
Estimated Market Value
$25.00 to $60.00 per board foot depending on figure intensity and size.
Wood Age Estimate
The sample appears to be freshly surfaced or reclaimed stock with approximately 50-100 years of biological age based on the density of the burl growth and oxidation levels.
Sustainability Status
Not listed on CITES Appendices or the IUCN Red List; generally considered sustainable but burl wood is a premium limited resource.
Workability
Difficult due to wild grain and high risk of tearout. Requires sharp tools and careful sanding. Glues and finishes very well, though voids may require epoxy filling.
Notable Features
Distinctive 'nutty' scent when worked. Contains juglone, which can cause mild allergic reactions in some individuals. Known for exceptional acoustic properties and aesthetic depth.
Finish Recommendations
High-quality oils (Tung/Linseed) or shellac to pop the figure, followed by wax or lacquer for protection. Void filling with black or clear epoxy is recommended for this specific burl sample.
Identification Confidence
High; the combination of circular burl eyes, rich brown heartwood streaks, and the specific chatoyancy in the lower ripple grain is characteristic of figured Juglans species.
