Vintage large rhinestone tulip flower design clip on earrings, silver tone with grey / green rhinestones and filigree backs

Large vintage subtle grey / green chunky rhinestone tulip design clip-on earrings in silver tone. Gorgeous floral design with the most beautiful detail. The earrings are not signed so I have puzzled about who may have made them. The earrings backs are filigree plates identical to ones used by Miriam Haskell. But the design is classic 60s-70s, during which time period Haskell pieces would have been signed.

The design is also reminiscent of Juliana pieces by Delizza and Elster - always unsigned, but I haven't seen examples using the filigree plates. Schreiner pieces were not always signed and did use these type of claws/prongs to set the rhinestones. But overall I have to say - maker unknown, but quality excellent. The symmetry of the design means the pair can be worn in two different orientations, with the tulip towards the face or outwards. The earrings are in very good vintage condition.
