I have two of these rare beauties, can you believe it! Collected over time, not found together.
This listing is for the larger one of the two...
 
Exquisite Swiss enamelled loupe circa 1820 finely decorated with red enamel, and with a portrait either side, a lady in a hat and the hint of a pink dress, a man with hear swept forward and wearing what looks like a blue toga.
 The portraits are framed within a circle of ceramic beads. A magnifying glass swivels out so you can inspect your jewels. Excellent condition
 
Swiss or french circa 1820
 
Weighs - 4.7g
