Although this beautiful necklace is vintage, it has not been worn.  Only tried on and stored for years.  Shows no signs of wear, but there is signs of age.  A small pock mark on medallion (pictured) and very slight something on the clasp, which is covered.  This has been stored over 20 years, so bound to have aged a bit.  Nice weight and great shimmer.  Givenchy logo appears on the clasp, which is nice and secure.  15" necklace has extender so it can be worn longer for an additional 18".
