Both sides of the exterior are engraved with different initial groups, but the inside of this locket is the real gem. One side has dark brown basket worn hair under a piece of rock crystal that fits perfectly into the heart shape. it is not cracked, chipped, or scratched at all. There is some denting on one side of the exterior or the locket, it is the side that houses the hair. There are no metal markings but it has been tested for gold content. The locket measures 1 inch long and does stay closed.
