Timber

The heartwood is light and dark chocolate brown. At 1010kg's/m3 the wood is hard, heavy, durable, close-grained and resistant to termites. It sandpapers well and takes oils and varnish well finishing with a satin like lustre. When freshly worked it has a distinctive, sweetish smell. The wood is almost indestructible. Samples taken from Great Zimbabwe, carbon dated to be between 1240 and 1530 years old, were found to be well preserved. It is used in musical instruments, turning and carving.
