14k gold and solitaire Opal tie tack, 1950s high quality, iridescent stone with excellent flash. Business, professional.

This wonderful understated tie tack comes in its original box. At 8mm wide and 9mm tall this piece has a lot of fire n the stone, and though understated, it certainly will be an accent piece for a business person's attire.
The stone is set in 14k gold, but the backer is not gold, which is typical cheapest of these pieces.
