Value & Sustainability

Estimated Market Value
$15.00 - $30.00+ per board foot depending on slab width, figure, and local market demand.
Wood Age Estimate
Recently harvested/milled log (likely within 1-3 years), freshly rough-sawn slab showing natural drying checks along the pith line.
Sustainability Status
Not listed in CITES Appendices; evaluated as Least Concern on the IUCN Red List; widely available from sustainably managed domestic forests.

Common Uses

Live-edge dining tables, island tops, desks, fine furniture, cabinetry, turned objects, and specialty architectural accents.

Geographic Origin

Eastern North America

Workability

Generally works very easily with both hand and power tools; glues, stains, and finishes exceptionally well, though saw marks will require flattening and planing.

Finish Recommendations

Flatten slab surface, stabilize checks/cracks with butterfly keys or epoxy resin fill, sand smooth, and apply penetrating oils (e.g., Hardwax Oil, Danish Oil, or Rubio Monocoat) or satin polyurethane to highlight natural grain and chatoyance.

Notable Features

Distinct contrast between sapwood and heartwood live edges; mild faint scent when worked; central longitudinal drying crack along tension line; high aesthetic value for single-slab furniture.
