Vintage natural abalone shell square screw back earrings. 3/4" X 3/4". Excellent condition. Note: we sell vintage items that were pre-owned and used. They may have signs of wear. This is not a defect but a natural character of a used product. I try to provide honest descriptions as detailed as possible. I ask my buyers to carefully read description, examine pictures, and ask questions prior to placing an order to avoid returns, losses, and disappointment for both of us. Thank you.
