The cultural treasures contained in the Duan Inkstone itself are actually similar to those in the inner-painted snuff bottle. However, it is precisely because of the natural treasures carried by the Duan Inkstone itself that the treasure content of this Duan Inkstone exceeds that of the inner-painted snuff bottle.

As for why Picasso's sketches and inner-painted snuff bottles do not contain natural treasures, this is a better explanation. Picasso's sketches are made of ordinary white paper, and the material of the inner-painted snuff bottles is glass. These two materials are not precious raw materials in nature, so these two things only contain humanistic treasures without any natural treasures.

But Duan Inkstone is different. The raw material for making Duan Inkstone is extremely rare stone. Although it is stone, it is also a very rare kind of stone.

In a sense, jade, gemstones, and jade are actually a type of stone, and the more precious Tianhuang stone and chicken blood stone are even more so. If we consider this aspect, the stone used to make Duan inkstones is also a gem, and an extremely rare gem. Otherwise, why is this kind of stone only produced in the Fuke Mountain, Lingyang Gorge, and Beiling Mountain in Duanxi, Guangdong Province?

The origin of the stones used to make Duan inkstones is even smaller than that of Burmese jadeite. If these stones are not precious, what else is precious?

There are only a tiny number of places in the world that produce this kind of stone, so it is no surprise that the treasures of nature are concentrated in these precious stones.
