I have a sterling DBTY bracelet from Tiffany. I only wore it once a long time ago and it fell off my wrist. The clasp must have undid itself slightly for the bracelet to open. Luckily I saw it happen and found my bracelet lying on the floor. I took it back to the store for them to check out the clasp and they said that it looked fine. I was still worried about losing it so I never wore it again since. Has anyone else also experienced this?
