DY Ay: Construction Quality Slipping?

Hey, remember that time my jewelry literally fell off me? I do. It was last Saturday night.

I was out with friends, "boozin', havin' a few laughs" as it's said in Chicago: The Musical. Anyway, I'm dressed sharp, my jewelry game sick. David Yurman on chest, wrist, and fingers. You know how I do. Someone says something that catches me as funny; I toss my head back in laughter... aaaaaand my necklace falls off me. 

Well, sort of. I was wearing a black diamond tag, set in black titanium. Turns out the tag is actually a pendant in two-pieces--an outer shell and an inner plate, the latter the piece on which the diamonds are arrayed. And that is the piece that fell off. Without having been so much as whacked, smacked, or jostled, the plate--clearly not well affixed--just took a soundless tumble out and down to the barroom floor. 

"Brian, your necklace, like, just fell off." 

Here's where I say thank God for friends. (Especially friends who notice stuff.) Here's where I also say what the hell?
