While I would like to see more Silver Eyes, particularly to get her to show some level, any level, of interest in her most unique power, it seems likely that Salem has systematically targeted them over the years. While we don't know how many skulls have been dimmed, given that a first-time user with no prior training, or even the most rudimentary knowledge of her true powers was able to petrify the biggest Grimm yet seen in a single shot, exterminating SEWs would probably be towards the top of Salem's to-do list.

It is possible that Ruby, or potentially the Rose bloodline is particularly potent, we have very little information to begin with, and nothing to compare them to.
