After posting the Gemstone Art by Anthony Pilon, we got a lot of requests for a tutorial. I was about to send Anthony a request to do one for our lovely BlenderNation readers, however he has already done it. What a cool dude!
Either way, I ought it to our readers to post it here, so enjoy this great breakdown by Anthony Pilon, and dare i say, a real gem this is!
(PS: I added captions on the images for explanations given by Anthony, so look out for them.)
