That's what this mineral is actually called, a type of jasper, but here's the thing: it comes exclusively from the mountains of China, and looks like that traditional style of Chinese painting.
But, in fact, it is the other way round: Chinese painting copies - or was at least inspired by - its naturally created dendritic lines.
And that drift of red (some might say blood)? That's typical of Chinese Picture Stone, and caused by chemical reactions during its creation millions of years ago.
What a story for a simple scarf! And what better to print it on than Chinese silk!
