Vintage Nina Ricci Pearl Earrings Clip-on Gold Plated

This is a wonderful pair of clip-on earrings made by Nina Ricci, probably during the 1980s or 1990s. They feature a large pearl centred within a gold plated square setting. These came from the estate of a shopaholic who bought tons of designer jewelry and hardly wore most of it. These measure 1 1/4 square and are in excellent condition.
Beautiful quality
