Sterling Hinged Filigree egg

Filigree hinged Pendant shaped in an egg. Can be used to place a fabric ball and put essential oil on it for scent or healing. Comes with a medium-sized spiral rope chain. Please see the measurements. The chain is stamped 925. I believe the pendant is sterling as well, but I can not find a stamp. It ages like Sterling, but I can't be 100% sure. The pendant has a large bail and can be put on a thicker chain. This is new w/o tags. See measurements.
