One of a kind LoveLock vintage heart lock. I can't even find the brand online anymore. Heavy necklace and pendant. I used to have an actual key to open the pendant but lost it years ago when it was on my neck, so I had to have the necklace cut off lol. I attached a sterling silver lobster claw clasp using sterling silver wrapped loops I created with a lower gage wire. It has been a solid system for wearing the necklace, for years now! Sturdy and strong, its a heavy piece. Some discoloration spots occured on the back of lock after living on a boat in saltwater for the better part of a year. Goth/industrial/fantabulous
