A mineral is a naturally occurring solid chemical substance formed through biogeochemical processes, having characteristic chemical composition, highly ordered atomic structure, and specific physical properties.
By comparison, a rock is an aggregate of minerals and/or mineraloids and does not have a specific chemical composition.
Yeah yeah - let's look at the pretty rocks, I mean minerals.

The lovely scarves below are silk featuring scans of rocks and minerals. It was hard to find an image that does them justice, when folded out they are quite unique and breathtaking. I came across the company Weston Earth Images via a show on ABC called Britain's Next Big Thing. The creator takes minerals and the inside of rocks and digitally scans them at a high resolution and creates these scarves, among other things. The second image is of their scanned Elestial Quartz.
The beautiful art print below is called Gemz and it is by New York artist Amber Ibarreche. I would love to see this expanded into a full wallpaper - it would be magic.
