I need a little advice/insight...

I'm considering proposing to my girlfriend on vacation which we're flying to and was wondering if anybody has any insight on the best ways to transport an expensive ring on an airplane safely.
I'm thinking bringing it on a carry on is the only way to do it, since there's no accountability for a lost ring on a checked bag...
But I could imagine going through TSA and the lady/guy on the scanner seeing the ring in my bag and being like "OOOOOHH nice diamond ring!" like a douche. Or giving me like a wink/nudge congrats type bullshit with my girlfriend right behind me, idk. Maybe I'm just extremely paranoid about the surprise being ruined.
<bot>: Anybody have experience bringing an engagement ring on a plane? Anybody with any experience with airports familiar with policies that might help me make the best decision here?
