Ebony tree block

Tamil Name - கருங்காலி கட்டை - Karungali Kattai 

Ebony is a general name for very dense black wood. In the strictest sense it is yielded by several species in the genus Diospyros, but other heavy, black (or dark colored) woods (from completely unrelated trees) are sometimes also called ebony. Some well-known species of ebony include Diospyros ebenum (Ceylon ebony), native to southern India and Sri Lanka, Diospyros crassiflora (Gaboon ebony), native to western Africa, and Diospyros celebica (Makassar ebony), native to Indonesia and prized for its luxuriant, multi-colored wood grain.
