Stamped 14k Stone has no visible chipping I tried scratching it & nothing Has made a dent. Doesn't mean that it's not man made. 6 of the accent stones are missing but I'm curious as to how else to tell if It's real or man made.

IDK, I don't own the proper tool to measure stones. Uncle was a jeweler, I spent a lot of time in his shop so I know the measuring tool I need.
