How to Identify Genuine Mahogany
Tell true Swietenia mahogany from its many namesakes by color, medium weight, fine even grain, ribbon figure, and end-grain pore pattern.

Start with color and how it changes. Freshly cut Genuine Mahogany is often a fairly pale pinkish- or salmon-brown, but it oxidizes over weeks and years to the warm reddish-brown or deep red-brown seen on aged pieces and on this sample. A rich, even red-brown with a subtle golden or coppery luster, and a clean boundary against a much paler yellow-white sapwood, is the classic signature. The color is more uniform and less purple or orange than many substitutes.
Read the grain and figure. Genuine Mahogany runs straight to interlocked with a medium-to-fine, even texture and a natural sheen. On quartered faces the interlock produces a soft ribbon or stripe rather than the bold, high-contrast stripe of Sapele; select boards show fiddleback, mottle, or feather-crotch figure. Heft matters too: it feels medium in weight — noticeably lighter than oak, maple, or the dense 'Santos' and 'Philippine' substitutes — which alone rules out several look-alikes.
Check the end grain with a lens. Genuine Mahogany is diffuse-porous, with medium-to-large pores in no specific arrangement, often containing reddish-brown or white gum/mineral deposits, and marginal (banded) parenchyma that can show as faint lines. There are fine, evenly spaced rays. Freshly worked mahogany has only a mild, nondescript scent — not the cedar-like aroma of Spanish cedar nor the peppery, spicy smell of Santos Mahogany, which is a useful quick discriminator.
The substitutes are the real identification challenge. African Mahogany (Khaya) is very similar but usually a touch coarser and more open-pored, sometimes pinker. Sapele and Utile (Entandrophragma) are denser, heavier, and show a much bolder, more regular quartered stripe, and Sapele carries a faint cedary scent. Philippine Mahogany / lauan (Shorea) is coarser, often more open-grained and stringy, and may show a faint resinous smell. Santos Mahogany (Myroxylon) is far harder and heavier, more orange-to-blood-red, and has a distinct spicy odor. When color, medium weight, fine even ribbon grain, and mild scent line up together, you are most likely looking at true Swietenia.
Frequently asked questions
How can I tell Genuine Mahogany from African Mahogany?
They are close. Genuine Mahogany (*Swietenia*) tends to be finer and more even in texture with a slightly warmer, more uniform red-brown, while African Mahogany (*Khaya*) is often a bit coarser, more open-pored, and pinker. Positive separation frequently needs end-grain examination or knowing the source.
Does Genuine Mahogany have a smell?
Only a mild, nondescript one. That faintness is itself a clue: a cedar-like aroma points to Spanish Cedar or Sapele, and a peppery, spicy scent points to Santos Mahogany, so a strong smell suggests a substitute rather than true Swietenia.
Why does my mahogany look pinkish rather than deep red?
Freshly cut Genuine Mahogany is often pale pinkish- or salmon-brown and darkens over time as it oxidizes, deepening to the rich red-brown of aged pieces. New stock simply has not developed its full color yet; sunlight and finishing accelerate the change.
Is a bold striped figure a sign of Genuine Mahogany?
Not usually. A strong, high-contrast quartered stripe is more typical of Sapele. Genuine Mahogany's interlock gives a softer ribbon, and its most prized figures are fiddleback, mottle, and feather-crotch rather than a bold regular stripe.
