Unique mother-of-pearl and silver magnifying glass, with a fold-out design. Each side of the outer case is carved from a single shell, with the outer, rough layer carved away to reveal the shining, opalescent surface beneath. The two halves are held together with a sterling silver frame, and the glass is held in by a ridged frame. This Georgian-era piece is distinguished by the unusual size - larger than other examples of this style and technique, and in very good condition. Measures 2.1/4" or 5 cm tall and 2.75" or 7.5 cm wide when unopened. The depth is wider than others I have seen. Piece is unmarked, manufactured in Great Britain.
