Walnut wood is one of the most loved and versatile hardwoods in the world of woodworking. Known for its rich dark color, beautiful grain, and lasting strength, walnut is a favorite for luxury furniture, fine cabinetry, carvings, and even musical instruments.
In this guide, we’ll cover everything you need to know about walnut wood—its types, unique features, uses, how it performs, and how to care for it.
Types and Where Walnut Comes From
Walnut wood comes from trees in the Juglans family. The most popular and valuable type is American Black Walnut (Juglans nigra), which grows in eastern North America. Other types include:
English or Persian Walnut (Juglans regia): Found in Europe and Asia, known for its fine texture
Claro Walnut (Juglans hindsii): A darker, more colorful walnut from California
Each species has its own color and grain, but they all share walnut’s well-known strength, stability, and beauty.
Walnut trees grow in mild climates and can reach over 100 feet tall, with thick trunks ideal for making large boards used in fine woodworking.
How Walnut wood Looks
Color
- The heartwood (inner part) of walnut ranges from light brown to deep chocolate brown, sometimes with hints of purple or red
- The sapwood (outer layer) is light-colored, almost white or pale yellow
- Often, the sapwood is steamed to match the darker heartwood
- Over time, walnut lightens slightly instead of darkening—developing a smooth, shiny patina
Grain
Walnut typically has a straight grain, but it can also have beautiful wavy or curly patterns, as well as burls and crotch figures. These unique features are highly prized in fine furniture and decorative veneers.
Walnut also has a natural shine, which highlights its grain and gives it a rich, classy look.
Physical Properties
Density: 610–640 kg/m³ — medium weight

Texture: Medium to coarse, with open pores—easy to sand and polish
Stability: Very stable wood—resists warping, cracking, or swelling
Durability: Naturally resists rot, fungus, and termites
Outdoor Use: Suitable for limited outdoor use, but best for indoors
Workability and Finish
Walnut is loved for being easy to work with. Whether you’re cutting, carving, sanding, or turning, it handles well with both hand and power tools. It’s:
- Strong but not too hard, so it’s perfect for detailed carving
- Easy to glue, screw, and nail
- Takes stain, paint, or polish well—but most people prefer a clear finish or natural oil to highlight its beauty
- Special grain patterns like burl, curl, or crotch require sharp tools and more care—but give incredible visual results, especially in veneers or decorative pieces.
