Purchased from a personal accessory shop. Only tried on and stored in a dark place. The clasp has a "silver top" marking on the back. These are large baroque pearls, approximately 8-10mm each. Comes with a velvet-like base and a black paper box. Please read the self-introduction. I pay close attention to inspection, but these items have been handled by others. Please refrain from purchasing if you are looking for perfection or are overly sensitive. Also, there is a possibility of a price increase or disposal after a certain period. Thank you for your understanding.
