Unique Dainty Mixed Metal Hexagon Necklace

This piece is unmarked except for a small tag at the clasp stamped with three interlocking circles. The 18" chain is oxidized and the half-inch hexagon is gold-tone. The shape is reminiscent of beehives, and the six-sided carbon atom which forms the basis of all living things. It was very meaningful to me during a specific time of my life which has now passed, and I'm not wearing it often. I really love matching up objects with their new owners--is it yours?
