This vintage Mid-Century book locket pendant is made from 14 karat yellow gold. The rectangular locket measures 1 inch in length and .75 inches wide, designed to resemble a miniature book. The front features line-etched detailing that mimics the spine and cover of a book, opening to reveal space for photographs or mementos inside. The warm yellow gold has developed a gentle patina over the decades, adding character to the piece.
