Abalone Earrings by DURI - Vintage

Abalone set in Silver Metal, they are approximately the size of an American Nickle and are heavier than they look, they are stamped with the designer's name DURI. I believe these are in new condition, I cannot wear Silver or any costume jewellery, these are from my Mom's Collection of Jewellery and like myself she could not wear these either. They show no signs of wear. Abalone is believed to bring guidance and calm emotions.
