How to Identify Kingwood

Start with color and figure. Kingwood is a medium to dark brown heartwood, very often carrying a distinct violet or purple undertone, overlaid with fine darker streaks that read as narrow stripes or bands on worked faces. On this sample you can see that medium-to-dark brown ground with darker streaking and a radial, wavy figure crossing visible growth rings. Sapwood, when present, is pale yellow to whitish and sharply set off from the heartwood — a clean line, not a gradual blend. Remember the color shifts: fresh cuts are most violet, and boards mellow toward warmer brown with light exposure, so an aged surface may look browner than a newly planed one.

Gauge weight and hardness in the hand. Kingwood is dense and heavy for its size and feels hard and cold — it resists a fingernail and clunks rather than knocks when tapped. A light, soft-feeling piece is not kingwood. The surface has a naturally oily, waxy sheen; freshly sanded or turned, it buffs to a glassy luster without finish, which is a strong supporting cue for a true rosewood.

Check the end grain and pores with a lens. Kingwood is diffuse-porous with medium to small pores, some containing dark or mineral-like deposits, and fine, even texture — no large open pores as in ring-porous oak or ash. The grain runs straight to interlocked or wavy. A faint rosewood scent may be present when freshly cut or sanded, mild and slightly sweet rather than sharp; scent alone is not diagnostic but reinforces a Dalbergia identification.

The main confusions are with related exotics. Tulipwood (Dalbergia decipularis / frutescens) is the closest — a sister Brazilian rosewood, but tulipwood is lighter overall with pink, salmon, and yellow tones and bold pink-red streaking, whereas kingwood is darker and more violet-brown. Cocobolo (Dalbergia retusa) is more orange-red to red-brown with dramatic irregular color variation and typically lacks the consistent violet cast. Purpleheart (Peltogyne) can look superficially violet but it is a different genus, oxidizes from dull brown to a vivid uniform purple, and lacks kingwood's fine dark streaking and oily rosewood luster. Katalox and other dark exotics are darker and more uniform, without the violet tone and striping. When in doubt, the combination of violet-brown color, fine dark streaks, oily glassy luster, and heavy very-hard feel points to kingwood.
