Authentic Vintage Givenchy Pendant Necklace

Excellent used condition! See photos for actual condition. Super vintage, super rare. Pendant has a gold tone Givenchy logo setting that attaches a polished spherical brown marble stone. The stone only has one very tiny nick (maybe 1mm?) that is not easily detected by eye - amazing for it's age! The stone measures about 7/8" in diameter. Total height of pendant is about 1.75", including bail. Gold tone chain measures 34".
