These are unusual square-shaped hoop earrings. They are large and impactful, making them a lovely hoop. They are hallmarked. They look even better when worn than in the photos. The clasp also closes properly. I measured them with a household scale, so the measurement is not exact. Please understand that the actual size may be slightly larger. Size: Approximately 2.5cm wide, 3cm long, and thick. I am using the UnoAerre tag, but these are not UnoAerre. No price reduction. I will not respond to requests for price reductions. #hoopearrings #k18 #YG #earrings #twist #square
