There are things to see here. Purple cubes with darker purple edges. Interesting growth structures on faces and edges. A rainbow. A nice fluorescence under longwave ultraviolet. And even though you think you only see cubes, look closely at the corners. There you can see other faces, albeit small ones. You might need to squint a bit, but the corners appear to be dodecahedron faces. Ex Joan Lamond Collection. Width of view 17.25mm. Stack of 30 images.
