Huo Sining's eyes lit up at the comment, "Is it very valuable?"
Su Qingqing was so irritated she wanted to roll her eyes, "Duh, do you know how rare ebony wood is? This thing has to be carbonized in the mud underground for thousands of years to form. In ancient times, it was used to make Buddhist statues, amulets, pendants, and accessories as talismans. To use it to craft a box is an extravagance I've never seen before."
Su Qingqing wasn't wrong in what she said, ebony combines the quaintness of wood with the charm of stone, its surface is smooth and the grain fine, closely resembling rosewood.
Ebony is valued for never fading, not rotting, not getting infested with insects, and its spiritual nature. Moreover, it's a non-renewable resource, which makes it highly collectible.
