Vintage Reflective Red Rhinestone Cufflinks Silver Tone Setting

This is an attractive pair of aurora reflective finished red rhinestone cufflinks made with a silver toned metal setting. In strong lighting, the reflective coating dominates and the stones reflect different tones, primarily purples and greens (see last 3 photos). I believe that the stones are of Austrian origin.
The stones are bevel cut and prong set. There are no makers marks, but these are very nice quality. They are in very good condition.
This is a very nice pair of vintage red rhinestone cufflinks - attractive colour and setting!
