A late Victorian Fob/Locket with a Daguerreotype.
Until the invention of the daguerreotype, hair jewelry, cameos and portrait miniatures were the main forms of memento jewelry. Daguerreotypes quickly eliminated the demand for portrait miniatures and for the miniaturists themselves who, for a short time before disappearing into obscurity, used their skill to colorize daguerreotypes. Jewelers began to produce ready-made empty brooches just waiting for a customer provided daguerreotype of a loved one to complete the piece. Hair mementos continued to be popular and were often paired with daguerreotypes to create a complete remembrance of a loved one.
Daguerreotypes were unique images, but the original could be re-daguerreotyped and shared with loved ones. Additionally, lithographic and engraved copies could be made. In this way, the pictures could be reproduced in books and periodicals changing the publishing business dramatically and creating a record for posterity.
