How to Paint Realistic Gemstones

Here is a tutorial I put together a few years ago that I wanted to finally share with you all. Earlier today I posted this on my Facebook page and mentioned I'd make a PDF available on this blog but I haven't been able to get that to work here but these pictures will be a better resolution non the less. Hope this is helpful. :)
Below is a link to a PDF version of this tutorial....at least I hope it works.
