The Sixth Commentary of the Seven Mountain Treatises mentions Smaragdus Jadeite. It states that this substance springs forth from Stonemarrow within the mountains, and will bring disaster to any mere mortals who touch it. Sustained contact with Smaragdus Jadeite by someone without a Vision over a prolonged period will, in less serious cases, cause a mild malady, while in serious cases, the patient may suffer a dramatic change of personality and fall seriously ill.
The Seven Mountain Treatises also records that Tianqiu Valley was once home to a mysterious kind of stone that would absorb the rosy hue of sunset after basking in it evening after evening over a long period, which became known as "Sunset Stone." However, the claim has never been proven. Today, this term is used generally to refer to all manner of brown-colored stones.
It also records that the whiter the sand nearby a Whitesand Coconut Tree, the better the quality of the coconuts that grow on the tree. For this reason, "Whitesand" is a term for coconut trees of the highest grade.
