Antique French Palais Napoleon III Egg Ormolu/Trinket Box

For your consideration, a beautiful French Palais Royale egg casket/ trinket box/ ormolu, based on my research , it is dated to the period of Napoleon III, circa the mid to later 19th century . This amazing rare surviving casket is made from lovely opaline tan tone glass in a birds egg shape very stylish at the time. The egg stands on three strong gilt ormolu metal legs, with ormolu leaf detailing to the top of each one along with dangling rings on the sides.  To the top is an ormolu tiny leaf detailing, the casket opens and closes with a strong push faster. The top is also hand painted with floral motifs. Overall , it is in a good antique condition with some light tarnish to the gilt metal and some light surface wear/scratches noticeable upon close inspection but not really visible when displayed. Please see all the photos for measurements and details.
