Nice and chunky antique compass pendant - which by the way looks fantastic with my pools of light locket that is also available.
The glass is chunky and domed as is the gold bezel, which gives it a great hand feel - and it also can be used as a magnifying glass!
 
In good working order
Stamped for 18ct on the curved bezel.
Weighs - 11.9g
Measures - 26mm diameter and approx 10mm deep
English circa 1890
