Sitka Spruce
Picea sitchensis • Softwood
Grain Pattern
Straight, tight, and uniform grain; quarter-sawn (vertical grain) orientation with very fine, even texture and no visible figure in this sample.
Color Description
Creamy white to light pinkish yellow heartwood; sapwood is not clearly demarcated. It has a high natural luster and tends to darken slightly to a golden yellow with light exposure and age.
Hardness Rating
510 lbf (Soft)
Durability Rating
Slightly Durable to Non-durable; low resistance to rot and insect attack when exposed to the elements.
Common Uses
Musical instrument soundboards (guitars, pianos, violins), aircraft components, masts and spars for boats, crates, and general construction.
Geographic Origin
Northwest coast of North America, ranging from Northern California to Alaska.
Market Value & Sustainability
Estimated Market Value
$5.00 - $12.00 per board foot; higher for instrument-grade 'Master Grade' tops which can exceed $100 per set.
Wood Age Estimate
Relatively fresh/newly processed; shows minimal oxidation and a bright, clean surface with modern pencil markings.
Sustainability Status
Least Concern (IUCN); however, old-growth stands are increasingly protected and regulated. FSC certification is common.
Workability
Excellent with hand and machine tools. It glues, stains, and finishes well, though its softness makes it prone to denting and requires sharp tools to avoid crushing fibers.
Notable Features
Outstanding strength-to-weight ratio; exceptional acoustic properties (high velocity of sound); generally has a mild, resinous scent when worked.
Finish Recommendations
Takes clear finishes like polyurethane, lacquer, and shellac well. For instruments, thin nitrocellulose lacquer is preferred to avoid dampening vibrations.
Identification Confidence
High; the combination of very tight vertical growth rings, creamy color, high luster, and lack of visible resin canals (at this resolution) is characteristic of tonewood-grade Sitka Spruce.
