How to Identify Ebony

Start with color and grain. Ebony heartwood is deep jet black, often with subtle brownish or greyish undertones and occasional fine streaking rather than a dead-flat tone, set against a sharply paler pinkish-to-greyish sapwood that is usually trimmed away. The grain is very fine, tight, and even, typically straight with closely-spaced, uniform growth and a smooth, almost waxy luster — the look captured on our sample. Unlike open-grained tropicals, the surface shows no visible pores to the naked eye.

The end grain is a strong confirmation. Ebony is diffuse-porous with very small vessels that are hard to see even with a lens, giving an almost featureless, homogeneous end surface — quite different from the large, obvious pores of iroko or wenge, or the ring/diffuse pores of oak and walnut. That poreless fineness, combined with the near-black color, is a reliable tell.

Weigh it in the hand. Genuine ebony is strikingly heavy and hard — roughly 1,000–1,100 kg/m³, Janka around 3,220 lbf — noticeably denser than most woods, and a small offcut will typically sink in water. It resists a thumbnail completely and feels cold and solid. It has little characteristic odor when worked, so a strongly scented 'ebony' is suspect.

Separating it from look-alikes matters because black is easy to fake. Wenge (Millettia) is dark brown-black but distinctly coarser, with prominent open pores and a visible black-and-tan striped figure — far from ebony's poreless surface. African Blackwood (Dalbergia melanoxylon) is a genuine dense black rosewood that looks similar but is oilier, faintly scented, and shows a rosewood pore structure. Katalox, black palm, and other dark tropicals are dense but show different pore or fiber patterns. Most importantly, watch for dyed or ebonized substitutes: a wipe with a solvent-dampened rag lifts color from a dyed board but not from true ebony, whose black is in the wood itself, and genuine ebony's weight and poreless end grain are hard to counterfeit.
