Vintage signed Sphinx citrine yellow / topaz orange glass riviere necklace, triangle shaped crystals set open-backed in silver tone settings

Gorgeous vintage glass rhinestone riviere necklace claw set in silver tone with large open back citrine yellow/orange faceted glass rhinestones emulating gemstones. A lovely example of this range of riviere necklaces, which the Sphinx company produced in many colours - however these crystal shapes and the signed panels are harder to find.

Sphinx were a highly respected UK brand who manufactured jewellery for Kenneth Jay Lane, Saks, Bloomingdales, Neiman Marcus and other high end stores. Thus, many of their pieces were not signed, but this one is on the reverse of each crystal-set panel. The necklace is in good vintage condition, fastening with secure old style hook and extender chain, meaning the length is adjustable between about 16.5 and 20 inches.
