The heartwood of gaboon ebony (Diospyros spp.) is usually jet black, with little to no variation or visible grain. Occasionally dark brown or grayish-brown streaks may be present. Can be difficult to work due to its extremely high density. Has a dulling effect on cutters. Tear-out may occur on pieces that have interlocked or irregular grain. Takes finishes well, and finishes to a high luster. Ebony is commonly used for small ornamental purposes, such as piano keys, musical instrument parts, pool cues, carvings. Great for knobs, pulls, inlays and accents in cabinetry. Somewhat difficult to machine, but worth the reward. Excellent turning wood. Africa.
