This is an agate as the world has never seen it.
Indeed, it is only visible with a seriously expensive microscope, and an equally expensive, specially adapted Nikon camera.

No wonder it has proved popular with luxury store buyers as it makes for a wonderful scarf in silk.
Available here at over £100 less than it recently was in Fortnum & Mason.
