- Scientific Name
- Diospyros crassiflora
- Origin
- Equatorial West Africa
- Appearance
- Heartwood is usually jet-black, with little to no variation or visible grain. Occasionally dark brown or grayish-brown streaks may be present. Grain is usually straight but can also be interlocked. Fine even texture with very high natural luster. Endgrain: Diffuse-porous; medium to large pores in no specific arrangement, few; solitary and radial multiples of 2-3; black mineral deposits present; growth rings indistinct; rays not visible without lens; parenchyma reticulate/banded, possibly marginal, apotracheal parenchyma diffuse-in-aggregates, paratracheal parenchyma vasicentric.

- Durability
- Ebony is rated as being very durable, with good resistance to termites and other insects.
- Workability
- Can be difficult to work due to its extremely high density. Has a dulling effect on cutters. Tearout may occur on pieces that have interlocked or irregular grain. Due to the high oil content found in this wood, it can occasionally cause problems with gluing. Finishes well, and polishes to a high luster. Responds well to steam bending.
