Vintage emerald green poured glass cabochon and silver tone rose and leaf necklace and brooch set, unsigned Joseff of Hollywood ?

Stunning silver tone and green poured class cabochon rose and leaf design statement necklace and brooch set - in presentation box. These are heavy pieces, steeped in quality. The most similar pieces I have found are by renowned maker to the Hollywood stars and studios Joseff of Hollywood. These pieces are however usually signed but this set does not have any marks or signatures.

The necklace has a length of about 16 inches and fastens with a large spring ring clasp. The brooch has a length and width of about 2 inches and fastens with a roll-over clasp and pin. The pieces are in very good vintage condition and are provided in a large, pre-owned, black faux leather hinged presentation box with minor signs of ageing.
