Where can you get G7 One back glass?

Hey, I grabbed a One earlier this year, and broke the back glass with it in my pocket. Is there anywhere I can get a replacement One-specific panel, or would it be easier to just get a ThinQ piece?

I’d like to get the One’s glass solely for that neat iridescent effect it had, but it looks like the ThinQ stuff would fit with just an extra clear spot where the sensors would be on the ThinQ.
