Truthfully there is no such thing as a brown Ebony. All ebonies by definition have no tone making them black, white, or some shade of grey. Brown Ebony, also known as Guayacan, is more closely related to Brazilwood. Brown Ebony is native to the drier regions of South America. Brown Ebony takes on a glass like polish when finished and has a rich brown tone with dark patterning through the grain.
