From Valentin Magro is this nice pair earrings. They are constructed from solid 18K yellow gold, weighs a nice 22.6 grams. Designed in the style of fireworks or a splash - these earrings are large at 1 1/8 inches tall and 7/8 inches wide. They have the clip on backs for non-pierced ears. Hallmarked at the back Valentin Magro 750. They are in good pre-owned condition that I see no issues. They weigh 22.6 grams. They were over $7000 when new and these are a steal.
