Sandalwood, the sweet-smelling wood from sandalwood tree, has long been considered as the rarest timber in the world. Sandalwood has a long-lasting distinctive soft warm precious-wood fragrance. The natural soothing fragrance of sandalwood has the effect to calm the nerves and relieve stress. Unlike many other aromatic woods, sandalwood retains its fragrance for decades. As a slow-growing tree, sandalwood takes hundreds of years to harden into timber, which makes it even more valuable.
