OC Homeworld Gem - YAG

YAG, short for Yttrium-Aluminum Garnet, is a purely artificial gem. Niobium-doped YAG makes for a rather strong infrared laser source. In grad school, I worked with a YAG laser (with avocado green case, a 1970s purchase by my advisor) that used a frequency doubler to get a green beam (and a half-frequency deeper IR beam we had to dump lest it bounce around being invisibly dangerous). YAG isn't my "gemsona," but it's as close as I'll get unless they make canonically male gems in the show.
