Replicating an illustration for the crystal structure of ferrihydrite

I came across this image of crystal structure in an article *[The Structure of Ferrihydrite, a Nanocrystalline Material](https://doi.org/10.1126/science.1142525)* [1]:


[![Crystal structure of ferrihydrite](https://i.stack.imgur.com/IYd2Z.jpg)](https://i.stack.imgur.com/IYd2Z.jpg)


Does someone know the software in which it was produced? I have been looking for a way to visualize crystal structures of some minerals but I am stuck looking for a piece of software capable of doing it. I am aware of Jmol, but it does not show crystal structures too well.

I think the software used could be Diamond (<http://www.crystalimpact.com/diamond/>)

Free (as in beer) alternative to Diamond, [Olex2](http://www.olexsys.org/) (works on Windows, Linux and MacOS), can also be used to replicate this structure (I used [COD-9011573 CIF](http://www.crystallography.net/cod/9011573.html)). Various bonds for cubane $\ce{Fe4O4}$ core, transparent polyhedra and custom coloring schemes are available out of the box:

There is also an extension [DrawPlus](http://www.olexsys.org/Olex2/Extensions/DrawPlus) available on a subscription basis which adds some bells and whistles alongside with extra convenient tools for visualization (though I never used it myself).
