Vintage French Couture Gripoix Belt or Necklace with Poured Glass Fob 70s France

Gorgeous vintage French couture belt or necklace with a chased metal gilt chain and a poured glass fob pendant - I believe by Maison Gripoix, and likely circa the 1970s. The chasing on the metal links is a really beautiful and distinctive floral pattern, and one that appears on other pieces they created. The poured glass design is similar to a quatrefoil or a cruciform, done in emerald green and ruby red on one side, and emerald green and a dark cobalt blue on the other. The wearable length is about 34 inches or so, and the fob hangs down about an inch and a half. It can be worn as either a belt or as a necklace.
