I really dislike it.
Crystal isn't even a jewel name. It is a style that gems (or just glass) are cut into. That's like saying Bouquet is a flower name.(I actually know a woman named Bouquet, ick)
I really dislike almost all gem names (except
Ruby,
Opal, and Jasper)I don't see
Jade,
Diamond, or
Emerald making a comeback at all, they all seem dated and out of use. I know a few Crystals, all in their late 20's/early 30's, so it's completely dated to the 70-80's.
