Finding good deco pieces is getting harder, and I couldn't not buy these earrings. 
Striking hexagonal bevelled black onyx panels house old European cut diamonds in a millegrain edged setting. So good. 
Tested as 18ct white gold (butterflies are 9ct white gold, but they do the job just fine, and it seemed frivolous to change them) 
Weight approx 1.13g 
Width approx 6mm
Diamonds total approx 0.15ct, nice bright stones, tested as natural, earth mined diamonds.
Excellent antique condition
