Crafting an Amethyst D20, then scratching all the edges!

[Music] foreign with a stone like this it's important to get the best yield you can at first I dopped this Stone up by hand but I could tell that I was leaving a lot of meat on the bone so being an engineer I used photogrammetry to scan the rock then I took a STL of my star cut shape and compared the two to find a really good orientation then to transfer that to the top I actually printed a negative of the stone into a little block that could fit into my transfer jig for perfect alignment [Music] oh [Music] foreign because this is a really complicated shape and I wanted to make sure I was getting the best yield I decided to cut the first side down kind of like a rough cut only then I flip the stone over and worked the second side after the second side is finished I'll come back to the first side [Music] [Applause] [Music] [Music] thank you okay so I almost have the profile down to the right shape and you can see some of the areas are the original amethyst surface like the corners there and that's okay because when we do the star cut it'll kind of cut into those and it's actually the best way to optimize the size of the die I've got a copper lap here I'm putting 12 100 grit on it [Music] and I'll smush that into the copper with a piece of Ruby use Ruby because it's really hard aside from diamonds it's like the cheapest one of the cheaper hard things [Music] okay I got all the star facets in it's looking great we'll go ahead and polish it up from here I used a different lap than I normally do for polishing this is because I needed really flat facets so that the Frosted edges would look really good like just really crisp lines this is a dark side lap with cerium oxide on it and it did get very flat facets they did take a long time though coming from 1200 Grit [Music] [Music] what's gonna make this die special is I want to frost the edges this is an effect that I've seen other Fasteners do and every time I see it it looks amazing so to do this I used 1200 grit on copper I didn't run the lab I just scraped the stone back and forth a few times [Music] foreign [Music] about three years ago I had some money burning a hole in my pocket I went on the internet to find the highest quality dice I could find and I just couldn't find what I was looking for I was really lucky because my dad's a hobbyist jeweler he had an old rickety faceting machine laying around so I was able to play around with that and it really reduced the barrier to entry I started cutting my first icosahedron out of like a sedimentary rock that I found in my backyard and it took me like 60 hours to cut the first one because I was using silicon carbide paper and it just didn't work very well but from there I started to perfect the process of cutting them and the numbering process took like eight months to figure out working 9 to 12 at night and I was kind of worried that I would never figure out a numbering process but eventually I got there and now I love the process as much as I love the dice [Music] because polishing the first side was so slow going from 1200 grit on copper I thought I would try a new lab so what I'm gonna try here is a zinc plus lab from gear loose lavitary and I'm gonna put 3000 grit on it this should speed up the polishing time a lot foreign [Music] [Music] foreign [Music] process is really stressful you get done spending hours cutting this beautiful stone and the numbering process is so tedious and there are so many ways to mess it up when all the effort is done and the dye emerges from the mask and I can Marvel in its beauty it makes all the hours worth it [Music] [Music] thank you
