I need some opinions on some name choices

I’ve been brainstorming ideas for the name of a type of crystal in my story I’m working on, and I’ve have a few that I believe to be keepers. They are: Lecriytrium, Aerthril, Dillthirium, Dithirium, Magnithril, Craonyx, and Mithinite.

If I could get the community’s thoughts on which name would fit best in a Steampunk-without steam type of setting. I will also add that the crystals have magnetic properties when energized. You can check out the Main Thread if your interested or have any questions about my project.
