Yellowheart (Euxylophora paraensis), also called Pau Amarelo, is a Brazilian hardwood that has bright yellow to lemon-yellow heartwood.

Yellowheart has lemon-yellow to golden-yellow tones. Like many tropical woods, the color mellows slightly over time with UV exposure, shifting toward a deeper golden or olive-yellow tone.

Yellowheart has a Janka hardness of approximately 1,790 lbf (7,960 N), making it significantly harder than most domestic hardwoods.

Yellowheart (Euxylophora paraensis) is native to Brazil, growing in the Amazon basin and tropical forests of Pará state.

Yellowheart is primarily used for decorative accents, inlays, cutting board strips, pen blanks, knife handles, and woodturning.

Yes. Yellowheart's bright yellow color mellows over time with UV exposure, shifting toward a deeper golden or olive-yellow hue. Applying a UV-inhibiting finish slows this process.

Yellowheart works well as a decorative accent strip in mixed-species cutting boards, where its vivid yellow color creates contrast against darker woods. It is hard and food-safe when properly finished with food-safe mineral oil.

Yellowheart is moderately easy to work despite its hardness. It machines cleanly with carbide tooling, sands well, and finishes to a smooth, attractive surface. Its main working challenge is its high density, which dulls tools somewhat quickly. Always use sharp carbide blades for best results.

Clear oil-based finishes, lacquers, and UV-inhibiting hardwax oils work best on Yellowheart to preserve its vivid color and show off its natural grain. UV-blocking finishes significantly slow the natural color mellowing process. Avoid water-based finishes that may raise the grain and add a slightly grey cast to the yellow surface.
