Sphinx victorian revival brooch - flea market find

Another flea market find. A Sphinx Victorial revival brooch,
Marked A831 and Sphinx.

This is the second Sphinx brooch I have found. The other brooch is much smaller.

More information about Sphinx:
The British company Sphinx made high quality jewelry. They made jewellery for many famous design houses, like Kenneth J. Lane, Saks Fifth Avenue, Butler & Wilson Neimans, and Bloomingdales and others. I understand and also heard Designer Henry Schreiner of Schreiner Jewellery Co which began in 1939 also designed for Sphinx. Their jewellery is becoming more and more collectible today.
