Color & Appearance

Rich reddish-brown to pinkish-tan heartwood with darker streaks and swirls, contrasting with a lighter sapwood margin. Exhibits high natural luster and deep chatoyancy that shifts in the light. Darkens to a deeper reddish-brown with age and UV exposure.

Value & Age

Estimated Market ValueNot an official valuation

8.00 to 15.00 USD per board foot for highly figured select stock.

AI estimate for general guidance only — not a professional appraisal. Actual value depends on grade, dimensions, condition, and local market demand.

Wood Age Estimate
Estimated 5 to 15 years since milling, based on stable surface oxidation and modern workshop context.

Common Uses

Fine furniture, cabinetry, decorative veneers, turning, and specialty woodworking projects.

Geographic Origin

Eastern North America, extending from New York down to Florida and west to Texas.

Workability

Tends to warp and twist during drying due to interlocked grain, but works well with both hand and machine tools once dry. Glues, stains, and finishes well, though sharp blades are needed to prevent tearout on figured areas.

Finish Recommendations

Takes oil finishes, shellac, and lacquer exceptionally well. A UV-inhibiting clear coat helps preserve the rich reddish tones from fading.

Notable Features

Famous for its striking multicolored figured grain (Red Gum). Can be prone to movement if not properly dried, but offers exceptional decorative aesthetic value.
