Le Bijou du Parfumeur (The Perfumer's Jewel) by Guerlain. Gold tone pomander ball pendant engraved with the Guerlain bee symbol, a black ribbon necklace. The pendant opens up and you insert the ceramic ball that you have soaked in fragrance, it closes with a magnetic clasp.
I don't know the exact date of manufacture but I am fairly certain it is post 2008.
