This is a most elegant Star Trek insignia from the Star Trek Movie Seires... seen best (Star Trek Movies II to VI) in Wrath of Kahn, Search for Spock, Voyage Home, Final Frontier, and Undiscovered Country.  This pin is gold with a touch of silver and is more elegant than the ones worn by the crew.  The gold with silver is meant for the Star Fleet Command officers... like the admirals.  The Enterprise crew is seen worn with the gold, green and white pins.  Their pins look cheaply made compared to this one.

Pin this Star Trek pin on a field jacket and get yourself the admiral pins for the shoulder Epaulettes and you will look like you belong in the command chair of the Federation's Finest Flagship... your starship... never mind the Enterprise.  That ship's name has been used and abused too many times.
