In the 1880s Tiffany, Wiese, Cartier and Faberge reigned supreme over the world of masculine elegance. The creation of the Boyer establishment which specialized in collar studs and removable shirtfronts (or "dickies") broadened its range to include cuff links and tie pins. These were mainly in mother-of-pearl, pearls, enamel, miniature mosaic work, and precious or semiprecious stones such as turquoise. Quite possibly antique cufflinks.
