Black rosewood, Dalbergia genus, has a slightly sour note in the woody fragrance, so it is called "black rosewood". The heartwood is chestnut brown, the wood is strong, and when it used as a floor, it gloss can be increased. The dark texture is like mountains hills that rising and falling, giving people into a kind of honest and reserved beauty, thats the reason why it is also called "black pearl of rosewood".

黑酸枝，黄檀属，木香中略带些酸调，故被称为“黑酸枝”。其心材呈栗褐色，木质结实，且作为地板时光泽度有加，深色的纹理犹如群山层迭起落，给人一种淳厚涵蓄之美，因此被称为酸枝木中的“黑珍珠”。
