I was searching for information on rocks and minerals today when I came across your blog: https://thomasfarleyblog.com
I liked your rockhounding related articles and also noticed you are currently working on a new book. Anyway, I happened to have two resources that might make good additional resources for your readers!
The first one is a list of free gemology courses and resources which I have compiled a couple of years ago: https://beyond4cs.com/free-gemology-courses-and-resources/
The other is more recently created, an animated infographic on how diamonds are formed and created.
Check it out here: https://beyond4cs.com/how-are-diamonds-made-and-formed/
Either way, would love to hear what you think about them! 😀
