iPhone 8 back glass alternatives?

Heya everyone,

My friend recently gave me their iPhone 8 after they utterly destroyed its screen and back glass plate. I have immediate plans to replace the screen, but I’m just gonna pick up a case and wait a bit on the back glass. So here’s my question:

Does any third party out there make back plate that isn’t glass? I kinda don’t care about the wireless charging feature, so it doesn’t really matter if the material isn’t conductive or whatever (I’m graduating up from an iPhone 5, so less is more to me.) A quick search turned up nothing.

Also I feel like all black on the rose gold mid-frame would look pretty neat!
